CHAPTER 1: INTRODUCTION

1.1 WELCOME TO THE IDM01 DRUM MACHINE!

1.1A If You Just Can't Wait…

Turn to section 1.4, 10 Steps to Instant Gratification, and start making sounds. Some of the
terms in that section may not make sense, but just follow the instructions, and get ready to
hear some great grooves and have a good time. When you're ready to learn more, return to
the beginning to learn IDM01 basics.

The goal of the IDM01's design team has been to create a musical instrument, not a computer
that happens to make sounds. They thank you for your confidence in this product, and hope
that you find the IDM01 a rewarding tool for self-expression that stimulates your creativity (and
tickles your fancy).

1.1B IDM01 Quick Description

The IDM01 includes over 230 high-fidelity drum/percussion sounds, and is easy to operate. As
you tap the 12 drum pads (each of which can be assigned to any of the available sounds), the
IDM01's on-board computer records exactly when you triggered the drum sound and the
dynamics of your playing. You can play back the part, and edit it in various ways.

Data is retained in memory even if the power is turned off. If the memory fills up with drum
Patterns and Songs, this data can be saved permanently to standard cassettes, or to MIDI
System Exclusive storage devices.

The IDM01 also includes a library of preset rhythm Patterns prepared by professional
drummers for those who want to start creating Songs in the fastest and easiest way possible.

1.1C About this Manual
The manual takes you through every function of the IDM01 in the following order:

1. Introduction: Gives the basic ground rules and also covers how to play back drum parts.

2. Record Setup: Tells how to set up the IDM01 to record and edit drum parts.

3. Playing Back and Recording Drum Patterns: Put theory into practice and come up with

some drum parts. Includes material on copying and erasing.

4. Creating and Modifying Drum Sets: The IDM01 includes 50 Preset "drum sets" with
particular choices of sounds, tuning, panning, level, etc. However, you can also create and
modify your own. Each Pattern can have its own associated Drum Set .

5. Song mode: Now that you have a bunch of Patterns, string them together into Songs.

6. MIDI Setup: Here's how to use the IDM01 as part of a MIDI system.

1

7. Backup: Now that you've come up with some great Songs and rhythm Patterns, it's time to
save them to a cassette recorder or MIDI system exclusive storage device.

8. Applications: This additional information will help you get the most out of the IDM01.

9. MIDI Supplement: This brief, entry-level explanation of MIDI explains the basic theory

behind the MIDI protocol.
Feel free to cover topics in a different order. For example, if creating a whacked-out Drum Set

is important to you, read the Drum Set section before you start recording. If you come up with
a great tune, skip ahead to the Backup section so that you don't accidentally erase the tune or
otherwise lose it. If you only want to use the IDM01 as a MIDI expander module, then the MIDI
Setup section might be a priority.

Experts as well as beginners should read the following "ground rules" (definitions, concepts,
and how to communicate with the IDM01) very carefully. The IDM01 is easy to use, but only if
you read and understand these basic principles.

Certain subjects, such as quantization and output assignments, will be familiar to experienced
drum machine users but new concepts to others. As a result, some sections contain
background material tailored specifically for beginners. These sections are identified as
"background" and set in a smaller type size.

1.2 GROUND RULES

The IDM01 drum machine consists of two main elements:

• The drum sounds themselves, recorded using16-bit resolution (the same resolution as CDs).
For additional realism, many sounds use advanced "dynamic articulation" techniques so that
these sounds, when hit loudly, have a different timbre than when they're hit softly.

• An internal computer to control and trigger the sounds. This computer simulates an
advanced, easily editable tape recorder.

The IDM01 offers two main modes, Perform (for playback) and Compose (for recording). You
can switch between these while the IDM01 is playing, making it easy to test out different
sounds without recording them and then drop back into record mode.

1.2A The Pattern/Song Recording Method

When recording with a drum machine, it's often easier to divide a song into shorter individual
Patterns and work on these rather than record an entire song. A typical Pattern might be 8,16,
or 32 beats long, and correspond to a verse, chorus, bridge, instrumental, intro, etc. While
recording these Patterns, the IDM01 will be in Pattern mode. The IDM01 holds 50 Preset (i.e.,
can't be edited) Patterns and 50 user-programmable Patterns, each of which can be from 1 to
128 beats long.

After perfecting these Patterns, Song mode offers two ways to create a song:

2

• Program a list of Patterns, in the order in which they are to be played.

• Select Patterns in real time, and the IDM01 will remember your performance.
The IDM01 stores up to 100 User-programmable Songs.
Breaking a song into Patterns saves time since elements of a song often repeat. Example: The

second verse might have the same drum pattern as the first verse. Rather than record the
same Pattern twice, simply record one Pattern, then list it twice when assembling a Song. This
also saves memory (thus leaving room for more Patterns and Songs) since listing a Song step
takes up much less memory than recording a Pattern.

1.2B The Four Different Types of Patterns

The IDM01 introduces exciting new Song construction techniques. The IDM01 excels at live
performance—something usually not associated with drum machines. The key to using these
advanced features is understanding the different types of available Patterns.

• Preset Patterns provide a variety of rock, jazz, pop, and other rhythms programmed by
professional drummers.

• User Patterns are Patterns you can program, edit, and save. The Preset/User button selects
between these two master banks of Presets. The only way to modify a Preset Pattern is to
copy it to a User Pattern, where it can be edited.

There are 50 of each type of Pattern, numbered 00-49. However, each numbered Pattern
actually contains four different "sub-Patterns":

• A pair of independent Main Patterns (A and B, selected by their respective buttons).

• A pair of associated Fill Patterns (A Fill and B Fill, selected by pressing the FILL button when
either A or B is selected). The Fills primarily provide transitional Patterns between Main
Patterns, which makes for more realistic drum parts. The associated Fill Patterns share the
same length, Drum Set, and name as their Main Patterns (e.g., if A is 16 beats, A Fill is 16
beats). Otherwise, they are independent.

The reason for pairing the two different A and B Patterns together is simply so that you can
switch back and forth between them rapidly in live performance or while improvising. However,
A and B Patterns can be treated as completely independent Patterns if desired and can have
different lengths, Drum Sets, etc.

Always think of the Main Pattern and its associated Fill as a unit. For example, if you copy a
Main Pattern to another Main Pattern, its Fill will travel along with it.

Note that even though there are "only" 50 Patterns, the A and B variations double that to 100
Patterns, and the Fills double that again to 200 Patterns. Added to the Preset Patterns, 400
total Patterns are available.

3

1.2C How "Looping" Simplifies Recording

To simplify recording in Compose mode, a Pattern will "loop" over and over again. Example:
Suppose you want to record an 8-beat pattern. While recording, the pattern will record through
all 8 beats, then immediately jump back to the beginning and continue recording through all 8
beats again. The IDM01 will remain in record mode, and continue to loop, until you press
STOP or switch over to Perform mode. You will hear any previously-played parts as you record
new parts.

You can also erase drum hits while the pattern is looping to correct for errors.

1.2D What's a Voice?

Each of the 12 large pads triggers a voice. A voice is a sound-generating element with several
variable parameters: Drum sound, tuning, volume, output assignment (the voice's audio output
can go to either one of two sets of stereo outputs, and furthermore, to anywhere within the
stereo field of the chosen set of outputs), and MIDI note number.

Each pad is velocity-sensitive: the harder you hit the pad, the louder the drum sound assigned
to the pad will play. Thanks to the dynamic articulation techniques mentioned earlier, the
timbre will often change as well, just like "real" drums.

There are eight levels of pad volume resolution, from soft to loud. However, when using the
IDM01 as a drum sound expander and triggering sounds via MIDI, they respond to all 127
MIDI volume levels.

1.2E About Defaults

A default is a setting that is automatically assumed until you purposely change it. Example:
When you turn on a VCR, it automatically defaults to Stop—you have to purposely tell the
machine to go into Record or Play. Stop is therefore the VCR's power-up default status.

The IDM01 includes a default setup that assigns particular drum sounds to particular voices
(pads), at certain level and pan settings. The default drum sound assignments are printed in
white on the pads. However, you can change these defaults and come up with any type of
"drum set" you'd like.

Defaults save time by giving you a setup that's instantly ready to go; sometimes you'll need to
change only a few parameters to customize the default setup to your liking.

Often the default is "whatever was selected last." Example: If the IDM01 was in Pattern mode
and Pattern 23 was selected when you turned off the IDM01, the next time the IDM01 powers
up it will be in Pattern mode with Pattern 23 selected.

1.2F Physical Layout

The IDM01 includes seven main types of controls, along with a group of connectors (located
on the back panel). The control groups (see diagram) are:

• Pads (play buttons). Tapping each button triggers an IDM01 voice.

• Function buttons. These six buttons select various functions, some of which include multiple
"pages" of options.

• Tempo/Page buttons. These alter the tempo and also select different "pages" present in the
Drum Set, Record Setup, MIDI Setup, and Backup functions.

• Pattern select buttons. These choose between the A, B, and Fill variations for a Pattern.

• Mode buttons. These choose between Pattern and Song modes, Perform (playback) and
Compose (record) modes, and the Preset and User patterns.

• "Tape recorder" buttons. These control playback and stop, and work similarly to a tape
recorder.

• Display and data entry buttons. The display informs you of the instrument's status, and also
prompts you for data from time to time. A detailed description of the display follows shortly.
The data entry buttons include number entry buttons (0-9) and up arrow (increment, or INC)
and down arrow (decrement, or DEC). The latter increase or decrease parameter values on
step at a time.

• Huge volume knob. If you're used to scratching a turntable, you'll love the feel of this knob. It
regulates the volume of the entire unit.

1.2G Display Layout

The LCD is divided into several "windows." Each window contains information that helps you monitor
the IDM01's status, and/or indicates what type of data should be entered.

• Name, "dialog" box, real time Song/Pattern readout, beat counter. This is the most commonly-used
area of the display. It shows Pattern and Song names, the beat counter if a Pattern or Song is playing,
and the Pattern (including A/B/Fill/Preset or User designators) that is currently playing in Song mode.
When acting as a "dialog box," it lists parameters and the value to be edited (e.g., MIDI channel and the
channel number).

• Pattern/Song readout (also Drum Set edit and drum pad readout). This shows the selected Song or
Pattern number; with Patterns, the A/B/Fill/Preset or User designators are also shown. If you have
edited a Drum Set to which a particular Pattern was assigned, the display also shows DRUMSET
EDITED. In operations that require selecting a drum pad, this window displays the drum pad number.

• Press PLAY. For some operations, it is necessary to press the PLAY button to confirm a particular
operation, such as copy or erase. This portion of the display will say PRESS PLAY if it is necessary to
press PLAY to complete an operation.

• Page number and tempo display. When stopped or running, this shows the current tempo and
includes a visual metronome block that flashes on the beat. For functions that have multiple "pages" of
parameters (Drum Set, Record Setup, MIDI Setup, and Backup), this portion of the display shows the
currently selected page number.

• Compose/Perform. This indicates whether the IDM01 is in Compose or Perform mode.

• Click. In Compose mode, shows the current click rhythm in standard music notation (or OFF if click is
off).

• Quantize. In Compose mode, shows the current quantization rhythm in standard music notation (or
OFF if quantization is off).

• Selected function. This shows which function is currently selected: Drum Set, Record Setup, MIDI
Setup, Backup, or Step Edit.

• Swing. In Compose mode, shows the current swing rhythm, expressed as a percentage (or OFF if
swing is off).

• Play/Record. If the IDM01 is playing and in Compose mode, this will say RECORDING. If the IDM01
is playing and in Perform mode, this will say PLAYING.

1.2H Text Protocols

Throughout the text, button names are shown in UPPER CASE and words that appear on the display
are shown in BOLD. When referring to a numbered step in a set of steps, the step number will be in
parenthesis—for example, step (4)—to prevent confusion with Song steps or step edit mode.

1.3A Entering Numbers

The IDM01 identifies Patterns and Songs, as well as many other parameters, with numbers.
You need to type in (enter) these numbers in a specific way (as described below).

1.3B The Cursor

When the IDM01 wants you to enter a number in the "Dialog" box, the display will show the
previously-entered number (or the default number), and the first digit will have a small
underline called the cursor. If the cursor is not present, the number is there for reference only.
You are expected to enter something only if the cursor is present.

1.3C Leading Zeroes
If a value to be edited is a two-digit number, you must enter a two-digit number. If the number

is a three-digit number, you must enter a three-digit number. If necessary, enter a leading 0
(i.e., a zero at the beginning of the number) to fill out the required number of digits. Example:
The beat length is a three-digit number. To enter a beat length of 16, enter 016.

1.3D Automatic Revert

This feature may confuse you at first, but save you from potential problems as you become
more familiar with the machine. If all the required digits of a number aren't entered within two
seconds, the display will revert back to the previous number, with the cursor under the first
digit of the previous number. This is handy because if you start to enter a new number, but
then change your mind halfway through, you don't have to key in (or remember) the original
number again—just wait two seconds, and the display will revert to the original setting.

1.3E The INC/DEC Buttons

The two small buttons with the up arrow and down arrow symbols (next to the number keys)
are called the INC/DEC buttons respectively.

Pressing the INC button once increases the value of the entire number indicated by the cursor
(not just a single digit) by one. Pressing the DEC button once decreases the value of the entire
number indicated by the cursor (not just a single digit) by one. Example: If the display shows
00 and you want to enter 01, tap the INC button once.

These buttons, and the TEMPO/PAGE buttons, also have a "scroll" feature. If you press and
hold a button, after a short pause the display will either increment or decrement at a rapid
rate.

1.3F Buttons that Toggle

The Mode buttons, FILL button, and several function buttons (DRUM SET, RECORD SETUP,
MIDI SETUP, and BACKUP) "toggle" between two states. Each button press sets the switch to
its alternate state. Example: Press the PATTERN/SONG button once to change from Pattern
to Song; press again to change from Song to Pattern. Example: Press RECORD SETUP to
call up the Record Setup menu; press RECORD SETUP again to get out of the Record Setup
menu.

1.4 10 STEPS TO INSTANT GRATIFICATION (SETUP AND CHECKOUT)

1. Connect the Main outputs (either left or right for a mono monitoring system, or both for

stereo) to a high-quality musical instrument amplifier or PA. The amp and IDM01 volume
controls should be all the way down (counter-clockwise).

2. Leave the MIDI jacks (rear panel) disconnected for now.

3. Plug the IDM01's AC adapter into the wall. The smaller plug inserts in the 9V AC Power jack

on the back.

4. Turn on the rear panel On/Off switch, then turn on the amplifier.

5. The LCD will show a sign-on message. The upper right of the display should say PATTERN
and not SONG; if it shows SONG, press the PATTERN/SONG button and the display will show
PATTERN.

Quantization shifts your playing to the specified beat while you play, so choose the desired
value before tapping out your rhythms. Remember that you can also change quantization while
recording if, for example, you want to record snare with eighth note quantization but high-hats
with 16th note quantization.

Note: The quantize value also sets the step length in Step Edit mode (section 2.9).

Background As you record a Pattern, quantization shifts all drum events to the nearest selected rhythmic value
to eliminate small timing errors. Example: With a quantize value of 1/16, all drum events you play will be shifted to
the nearest 16th note.

Quantization is most effective when used sparingly. If you're recording a drum part, quantize the kick and snare,
but try recording the hi-hat in real time (or quantize the hi-hat, and record the snare in real time). Another trick is
to combine both quantized and non-quantized parts. Example: hand claps often sound too mechanical when
quantized—when humans clap hands, you end up with a bunch of different sounds happening within a few
milliseconds of each other. A good way to simulate this effect (yet still have a rock-solid rhythm) is to record a
quantized hand claps part, then turn off quantization and try to double the part. Sometimes what you overdub will
be right on the beat, but sometimes it will be off by just enough to add that human touch.

Swing shifts notes as specified while you record, so choose the desired value before tapping
out your rhythms.

Background Swing affects the timing of pairs of equal-value notes. Each note normally defaults to taking up
50% of the total duration of both notes; adding swing lengthens the first note of the pair, and to keep the total
duration of both notes the same, shortens the second note of the pair. This imparts the kind of feel found in
shuffles and some jazz tunes. Example: With Swing set to 62%, the first note of the pair takes up 62% of the total
duration of the pair of notes, while the second note takes up 38% of the total duration.

The display says VELOCITY. To select the desired dynamic response, use the INC/DEC or

= Fixed 7, 8 = Fixed 8, 9 = Soft, and 0 = Loud). Medium can be selected only with the
INC/DEC buttons.

Background This feature accommodates players with a heavier or lighter touch. Referring to the diagram, soft
response weights the response toward softer sounds; with medium response, the level is directly proportional to
how hard you tap the pad; loud response weights the response toward louder sounds.

Fixed volume plays back the associated drum sound at one of eight possible volume levels. With Fixed Volume 1,
all drums assume the level of the softest possible tap, regardless of how hard you tap the pads. With Fixed
Volume 8, all drums assume the level of the loudest possible tap, regardless of how hard you tap the pads. Fixed
Volumes 2-7 provide the levels between the softest and loudest extremes, with lower numbers giving softer
levels.

2.6 PAGE 6: ADD/REMOVE BEATS FROM PATTERN END (LENGTH)

This option either adds beats to, or subtracts beats from, the end of the Pattern. The Pattern
length can be set prior to, or after, recording. Shortening a Pattern's end point erases any
drum events that fall outside the remaining part of the Pattern; lengthening a Pattern's end
point adds silence at the end of a Pattern. It is also important to note that changing a Pattern's
length also changes the length of the associated Fill Pattern.

The display says ### BEAT and LENGTH. This indicates a Pattern's length in beats (quarter

number; enter leading zeroes if necessary). To prevent accidental length alteration, you must
press PLAY before the IDM01 will store the new Pattern length. The display shows CHANGED

Background Odd time signatures are not a problem since Patterns can be any number of beats (up to 128).

Example: For a measure of 13/4 followed by a measure of 5/4, program a 13-beat Pattern and a 5-beat Pattern.

2.7 PAGE 7: ADD/REMOVE BEATS FROM PATTERN BEGINNING (START)

This option either adds beats to, or subtracts beats from, the beginning of the Pattern. The
Pattern length can be set prior to, or after, recording. Shortening a Pattern's start point erases
any drum events that fall outside the remaining part of the Pattern; lengthening a Pattern's
start point adds silence at the beginning of a Pattern.

The display says ### BEAT and START. This indicates a Pattern's length in beats (quarter

number; enter leading zeroes if necessary). A smaller value compared to the original length
will remove the difference, in beats, from the beginning of the Pattern. A larger value will add
the difference, in beats, to the beginning of the Pattern.

Background An example will help clarify how beats are added to or removed from the beginning. Assume an
original length of 008 beats. Changing START to 007 will delete 1 beat from the Pattern beginning. Therefore,
what had been beats 002-008 will now be beats 001-007. Because a beat was removed, the Pattern will be 7
beats long.

Changing START to 009 will add a beat to the beginning of the Pattern. What had been beats 001-008 will now
be beats 002-009. Because a beat was added to the beginning, the Pattern will be 9 beats long and the beat
added at the beginning will be silent.

2.8 PAGE 8: OFFSET A PATTERN OR DRUM PART

Offset shifts a Pattern or individual drum parts ahead of or behind the beat in 1/384th note
increments to allow for altering the "feel" of a piece. This only affects already-recorded parts.

1. The IDM01 should be in Pattern mode and stopped. The display says OFFSET, which will
be 00/384 (no offset).

2. Press the pad to be offset (as confirmed by the display). If you don't select a pad, offset
affects the entire Pattern.

3. Enter the two-digit offset value with the INC/DEC or number buttons. Positive numbers shift
events ahead of the beat (lead), negative numbers shift events behind the beat (lag).
The default is positive numbers; to enter a negative number with the number buttons, press
DEC first. Example: To offset a part 1/16th note later, enter -24 as the offset value since 24
sub-beats equals a 1/16th note.

Press PLAY to enter this number into the IDM01. To apply the same amount of offset to
additional pads, press the next pad then press PLAY.

Notes: The display counter resets after you exit the function. Therefore, it does not keep track
of the total amount of offset, but only changes in offset.

Drums offset to before the first beat "wrap around" to the end of the Pattern; drums offset past
the end of the last beat "wrap around" to the beginning of the Pattern.

2.9 PAGE 9: STEP MODE RECORDING (STEP MODE)

The display shows STEP MODE? This is your "gateway" to step editing, which provides
detailed Pattern editing and recording. To enter the step editor, press PLAY.

The display now shows the beat and sub-beat. If a drum event exists on this beat/sub-beat, the
display will also show the drum pad that played the event and the event volume. If more than

15

one drum event occurs on the same sub-beat, the PAGE UP/DOWN buttons step forward or
backward respectively through each drum one at a time.

If no drum event exists on this beat/sub-beat, the display will show no pad number, and
EMPTY in place of volume data.

To navigate through the steps at the current quantization rate, use the PAGE UP button to
move forward or PAGE DOWN to move backward. If a drum exists between those beats that
fall on the current quantization value, the drum will sound as you go past it, but the display will
not stop on that drum.

If swing is on, step mode will step in "swinged" increments (see section 2.2).

Background Step mode provides detailed Pattern editing. (Note that "step" does not refer to Song steps, but to
the steps in a Pattern that hold drum events.) You can move through a Pattern one step at a time, stop at each
event as desired, and delete the event, add an event, or change an event's volume. While occasionally somewhat
tedious, Step Edit mode allows editing drum parts to your exact specifications.

Each step (also called a sub-beat) is 1/96th of a beat in duration, so at maximum resolution it takes 96 steps to
"move through" a quarter note. To save time, you can step through the Pattern at various note values, as set by
the quantization value (which is why it's preferable to select the quantization rate at which the Pattern was
recorded). Example: A 16th note consists of 24 sub-beats, so setting the quantization value to 1/16 lets you step
through the Pattern 24 sub-beats at a time. The following chart relates the number of sub-beats to
note/quantization values.

Use the PAGE buttons to select the step where the drum is to be added. Press the pad that
corresponds to the sound you want to add. That drum, along with its volume (how hard the pad
was hit), will be recorded into the displayed step.

If you play a pad and there is already a drum event played by that pad on the displayed step,
you will edit the volume rather than add another event. This is true even if there are several
events on the displayed beat, and an event other than the one to be edited is showing.

2.9B Erase a Drum Sound From a Step

Use the PAGE buttons to locate the step containing the drum to be erased. While holding
down the ERASE button, press PLAY. The drum that was being displayed will be erased.

2.9C Change a Drum Sound's Volume in a Given Step

Use the PAGE buttons to select the step containing the drum whose volume needs to be
changed. Either press a number button from 1-8 (1=softest, 8=loudest), use the INC/DEC
buttons, or tap the displayed drum pad at the desired level. If you play a pad to change the
level and there are several events on the same step, the display need not show the specific

To record, choose Compose mode (as shown in the display). This also activates the click.

To listen, choose Perform (this de-activates the click). You can drop in and out of these two
modes as you record. While the IDM01 is in either mode, you can change Pattern quantization,
swing, click rhythm and volume, pad velocity response, name, drumset, drumset parameters,
and MIDI parameters. You can therefore keep the groove going at all times, even while you
make adjustments prior to recording another part.

NOTE: Compose mode cannot be selected when using Preset Patterns, since they

cannot be altered. If you wish to alter one of the Preset Patterns, copy it to
an empty User Pattern first. (see section 3.3A)

3.1C Set Pattern Tempo

The tempo range extends from 20 to 255 beats per minute. Tempo can be changed while the
IDM01 is stopped or running. There are two ways to set tempo.

• Before initiating Pattern play, tap the STOP button several times at the desired tempo. The
IDM01 will average the time between taps and derive a tempo; the display will update the
tempo with each tap. If a footswitch is plugged into the Count/A/B/Fill jack, tapping the
footswitch at the desired rate is equivalent to tapping the STOP button. These techniques work
only if the IDM01 is stopped.

• Use the TEMPO/PAGE up and down buttons. Press once to increment/decrement 1 BPM at
a time, or press and hold to scroll through the tempo values.

Background While in Pattern mode, the tempo remains as is until changed because the tempo is a global
setting—it is not stored with individual Patterns. If you switch over to Song mode (Chapter 5) and the
programmed Song tempo is different, the IDM01 will assume the Song's tempo—even if you switch back into
Pattern mode—until the tempo is changed again (either manually, or by selecting a different Song).

3.1D Select Individual Patterns

1. Make sure the IDM01 is in Pattern mode.

2. Enter a two-digit Pattern number (remember to enter a leading 0 if necessary).

3. Press the A button to select the A Main Pattern, or B to select the B Main Pattern. To select

a Fill Pattern, first select the desired Main Pattern (A or B) then press the Fill Button.

4. Press PRESET/USER to select either a Preset or User Pattern.

RECORDING

COMPOSE

TEMPO

When a Main Pattern reaches its end, it will loop back to the beginning and continue playing
from that point unless you select a new Pattern, selected a Fill Pattern initially, or stop the

If you select a User Pattern that contains no data, the display says EMPTY PATTERN. If you
select a User Pattern that contains data but has not yet been named, the display says NO
NAME.

3.1E Stop/Restart a Pattern

1. To stop the Pattern, press STOP.

2. To restart the Pattern from the beginning, press PLAY. Pressing PLAY will always restart a

Pattern from the beginning, regardless of whether the Pattern is stopped or already playing.

3.1F Using the Start/Stop Footswitch
When the IDM01 is stopped, pressing a footswitch plugged into the Start/Stop footswitch jack

is equivalent to pressing PLAY. When the IDM01 is running, pressing the footswitch is
equivalent to pressing STOP.

Background The rear panel Start/Stop footswitch jack accepts a momentary, normally open or normally closed
footswitch (available at most music stores) for remote or foot control of the stop and start functions. The IDM01
checks the footswitch on power-up to determine whether it is normally open or normally closed, so make sure the
footswitch is plugged in (and you're not pressing it down) when you turn on power.

3.1G Select New Patterns While in Perform (Playback) Mode

In Perform mode, you can select a new Pattern number (with the desired A or B designator) or
switch from A to B Patterns within a Pattern number at any time. The newly-selected Pattern
will play back as soon as the current Pattern plays through its entire length. The display shows
the Pattern to be played next.

To select a new Pattern in Perform mode, enter the two-digit Pattern number. If an A Pattern is
currently playing, the new Pattern number will play the A variation. If a B Pattern is currently
playing, the new Pattern number will play the B variation.

You can also enter a two-digit Pattern number followed by A or B or PRESET/USER to call up
an A or B or Preset or User Pattern, regardless of the Pattern that is currently playing. Fills are
a special case that will be discussed next.

Notes

• If you change your mind or select the wrong Pattern, you can select a new Pattern number at any time before
the next Pattern begins.

• If you press STOP before the next Pattern begins playing, the IDM01 will stop and remain on the currently
selected Pattern.

• Shortcut: To choose the next higher-numbered Pattern than the one in the display, press the INC button (if 49 is
the current Pattern, pressing INC calls up Pattern 00). To choose the next lower-numbered Pattern than the one
in the display, press the DEC button (if 00 is the current Pattern, pressing DEC calls up Pattern 49).

• If you select a new Pattern and press PLAY, it will immediately start playing the next Pattern.

3.1H Select Fill Patterns in Perform (Playback) Mode
Fill Patterns are the key to creating expressive drum parts. However, Fill is a sophisticated

feature that requires some explanation.
Remember that Fills are always the same length, and use the same Drum Set, as the

associated Main Pattern. This lets you "drop in" a Fill at any time. As soon as you press the
FILL button, the Fill takes over from the Main Pattern and starts playing until the end of the Fill.

Generally, Fills are transitional Patterns. Example: Suppose an 8-beat A Main Pattern is
playing and you press the FILL button on beat 4. The A Fill Pattern will play the last 4 beats
and then automatically transition into the B Main Pattern. Conversely, if B Main is playing and
you press Fill, after B Fill has played, the IDM01 will transition to the A Main Pattern. You can
select the Fill at any time the Main Pattern is playing.

However, Fills do not have to be transitional Patterns. If you press the FILL button (or
footswitch) before the Fill has finished playing and hold it down until after the Fill has played

(i.e., past the downbeat of the next Pattern), the IDM01 will return to the original Main Pattern.
Example: Suppose an 8-beat A Main Pattern is playing and you press the FILL button on beat

4 but hold it down past beat 8. The A Fill Pattern will play the last 4 beats, then the IDM01 will
return to the A Main Pattern.

Fills cannot start on the downbeat since a Fill, by definition, starts at some point into the Main
Pattern. However, anything you record on the Fill downbeat will play on the first downbeat
following the Fill (i.e., the downbeat of the next Pattern). To show why this is a useful feature,
consider that when coming out of a fill, you'll often want to hit something like a cymbal crash on
the downbeat of the next Pattern yet not have that crash repeat every time the Pattern plays.
This way of handling Fills lets the downbeat cymbal crash be part of the Fill instead of the
Pattern.

A footswitch plugged into the Count/A/B/Fill jack duplicates the FILL button function when
playing Patterns in Perform mode.

Background This way of handling Patterns explains the logic behind having A, B, and Fill Patterns. In typical
pop tunes, A would be the verse and B the chorus. A Fill provides the Fill that transitions from verse to chorus,
and B Fill provides the Fill that transitions from chorus to verse. Thus, one of the numbered Patterns may be all
you need to put together a tune.

This structure makes it possible to put together songs in minutes using the Preset Patterns. It also makes it easy
to play drum parts live. For example, if there's a solo happening over the A Main Pattern, you can keep the

21

Pattern repeating until the solo is about to end, at which point you select the Fill that leads out of the A Main
Pattern.

3.1I Record a Pattern

An empty Pattern defaults to an 8 beat length, with 16th note quantization and swing off (50%).
If you need to change the length, it's best (though not essential) to do so before recording.
Other parameters can be changed while you're recording.

To record, select the desired User Pattern. Select Compose mode and press PLAY.
Remember that you can switch between Compose and Perform while recording.

As you record, the display will show the current beat number and the tempo indicator will flash
at the current tempo. You will hear any drum sounds already recorded in the currently selected
Pattern.

To record drum parts into the Pattern, tap the drum pads, or send MIDI data to the IDM01
(sections 6.1 and 6.2) that triggers corresponding drum notes. The Pattern will "loop" during
the record process so that you can overdub different drums on different passes.

To exit Record mode, press STOP. Pressing PLAY while in Compose mode will re-start the
Pattern from the beginning; the IDM01 remains in record mode.

Note: When sending MIDI data into the drums when the IDM01 is not recording (i.e., the
IDM01 serves as a drum sound expander module), the drum sounds respond to 127 different
levels of dynamics. However, if MIDI is used as a trigger during the recording process, the
Pattern will "quantize" the incoming level to the nearest of eight levels—the same eight levels
produced by tapping the pads at various levels.

3.1J Select New Patterns and Fills While in Compose (Record) Mode
In Compose mode, Main Pattern selection works in the same manner as Perform mode—

select a Pattern number (with the desired A or B designator), and the newly-selected Pattern
will play back as soon as the current Pattern plays through its entire length. The display will
show the Pattern to be played next.

In Perform mode, Fills are transitional Patterns. If you press FILL in Compose mode, a Fill will
continue playing—not transition to a different Pattern when it's finished playing—so you can
record into it, like a standard Pattern. Remember, as mentioned earlier, that the Fill also plays
the downbeat of the next Pattern.

If a footswitch is plugged into the Count/A/B/Fill jack when recording Patterns in Compose
mode, pressing the footswitch will switch a Main Pattern over to its associated Fill. The Fill will
continue playing until you press the footswitch again, at which point the IDM01 will revert to the
associated Main Pattern.

3.1K Using Fill to Create Repetitive Drum Hits

22

As mentioned earlier, the FILL button performs two different functions. We've already covered
how to use the FILL button for Pattern selection, however, it can also trigger a drum sound at
the current quantization rate (e.g., eighth notes, 16th notes, etc.; if quantization is off, though,
this function is inactive) and swing value. This allows playing a series of drum hits without
having to repeatedly press the pads, and is typically used to create steady 16th note hi-hat
parts, quarter note kick drum parts, snare rolls, etc.

1. The IDM01 should be in Compose mode and recording.

2. Press a pad on the first beat of what will be a series of hits and hold it down.

3. Immediately after pressing the pad, press and hold the FILL button. The drum will be re-

triggered at the current quantization rate for as long as the pad and FILL buttons are held
down. All hits will be at the same volume as the first pad hit.

Caution: If you don't hit the drum first, pressing the FILL button will select a Fill Pattern.

3.2 ERASE FUNCTIONS

3.2A Erase Mistakes While Recording

While the IDM01 is recording, you can erase any individual drum event or series of events in
real time to fix up errors. Erasure occurs only on those beats that coincide with the current
quantization and swing values; turn quantization off to erase a drum wherever it occurs.

1. The IDM01 should be in Compose mode and recording.

2. Press and hold ERASE.

3. While holding down ERASE, press the pad corresponding to the sound to be erased just

before the first event to be erased, and release just after the last event to be erased. To
erase a single event, tap the pad on that single event.

3.2B Erase an Entire Pattern

If you erase both Main and Fill Patterns associated with a numbered Pattern, or you erase a
Main or Fill Pattern and the other is empty, the Drum Set assignment (but not its Drum Set
parameters), name, and length will revert to the default settings (i.e., the Drum Set with the
same number as the Pattern, EMPTY PATTERN as the name, and a length of 8 beats).
However, as long as either a Main or Fill Pattern contains previously-programmed data, the
numbered Pattern will remember the Drum Set assignment, name, and length.

1. The IDM01 must be in Pattern mode and stopped to allow erasing a Pattern.

2. Enter the two-digit Pattern number to be erased with the number or INC/DEC buttons.

3. Press and hold the ERASE button. The display says PATTERN ERASE?

4. While continuing to hold the ERASE button, press PLAY. The display says PATTERN
ERASED, followed by FILL ERASE? .

23

5. While continuing to hold the ERASE button, press PLAY again. The display will read FILL
ERASED.

6. Release both buttons.

Note: To retain the Drum Set assignment, length, and name when you erase a Pattern, hold
ERASE and tap each drum pad. This erases the drum events, but retains all other Pattern
parameters.

3.2C Erase All Events Played by a Particular Drum Pad

This erases all events in a Pattern played by a specific pad. The Drum Set's parameters are
not altered.

1. The IDM01 should be in Pattern mode and stopped, in either Perform or Compose mode. To
erase while recording, see section 3.2A.

2. Press and hold ERASE.

3. While holding down ERASE, tap a pad to erase all events played by that pad. The display

shows the drum pad number whose events were erased. You can continue to erase more
drum sounds while ERASE is held down.

3.3 COPY FUNCTIONS
The following Copy functions assume that you are copying a Main Pattern to a Main Pattern

(remember, copying a Main Pattern to another Main Pattern copies the Fill along with it). Other
combinations take the following rules into account.

• Copying a Main Pattern to a non-empty Pattern or to itself appends the Fill to the existing Fill,
as well as appends the Main Pattern to the existing Main Pattern.

• If you copy from Main to Fill (or vice-versa) within a particular numbered Pattern, the
destination will be erased and replaced with the source Pattern since Main and Fill Patterns
must have the same length. This is useful if you want the Fill to contain variations on the Main
Pattern—just copy the Main to Fill and make your additions/changes.

• Copying a Fill to a Fill follows the same rules as copying a Main Pattern to a Fill.

• The only copy technique that appends a Pattern to another Pattern is copying a Main Pattern
to another Main Pattern.

3.3A Copy, Append, and Double Patterns

1. The IDM01 should be in Pattern mode and stopped.

2. Select the Pattern to be copied.

3. Press and hold the COPY button, and keep holding it down until step (6). The display says
COPY TO PATT.

4. Enter the destination Pattern number into which the current Pattern will be copied with the

INC/DEC or number buttons.

24

• Copying a Pattern to a blank destination Pattern replaces the blank Pattern with the original
Pattern data.

• Copying to a Pattern that already contains data appends the original data to the end of the
data in the destination Pattern. If this would result in a Pattern with more than 128 beats, the
display will say TOO MANY BEATS.

• Copying a Pattern to itself doubles the length.

• The Drum Set assignment and Pattern name are copied along with the drum data only if the
destination Pattern is empty.

5. Press PLAY. The display says COPY DONE.

6. Release the COPY and PLAY buttons.

3.3B Copy One Drum Pad's Part to Another Drum Pad
Merge: When the destination drum pad already has a pattern, the source pattern will be

merged with the destination pattern. Note that if the two parts contain events for the same pad
on the same beat, only one event will prevail and it will take the level of the source Pattern
event.

Sound Stacking™: When the destination drum pad is empty (no recorded pattern), the source
pattern will be copied and any drum sound assigned to the destination drum pad will play the
exact same pattern as the source drum pad. This technique lets you stack multiple drum sounds
together to create monster composite sounds. See section 8.3: Sound Stacking.

1. The IDM01 should be in Pattern mode and stopped.

2. Select the Pattern containing the drum part to be copied.

3. Press and hold the COPY button, and keep holding it down until step (7). The display says
COPY TO PATT.

4. Tap the pad to be copied. The display shows the pad number (e.g., D8 if you hit pad 8).

5. Tap the destination pad that should hold the copied part. As long as COPY is held down, the

destination pad can still be changed by selecting another drum pad.

6. Press PLAY. The display says COPY DONE.

7. Release the COPY and PLAY buttons.

3.3C Copy a Single Drum Pad's Part to a Drum Pad in a Different Pattern

This copy function merges the source drum pad rhythm with the destination drum pad rhythm in a
different Pattern. To replace the destination rhythm with the source rhythm, first erase the destination
pad rhythm to be replaced (section 3.2C).

1. The IDM01 should be in Pattern mode and stopped.

2. Select the Pattern containing the drum part to be copied.

3. Press and hold the COPY button, and keep holding it down until step (8). The display says COPY TO
PATT.

4. Enter the destination Pattern number to which the drum part should be copied.

5. Tap the pad containing the part to be copied. The display will show the drum number (such as D2 if

you hit pad 2).

25

6. Tap the destination pad to which the source part will be merged. Often when copying to a different
Pattern, this will be the same drum pad number as selected in step (5). As long as COPY is held down,
the destination pad can still be changed by selecting another drum pad.

7. Press PLAY. The display says COPY DONE.

8. Release the COPY and PLAY buttons.

3.3D Copy a Pattern to Another IDM01 Via MIDI

The IDM01 can send User Pattern system exclusive information (for the Main and Fill Patterns) to
another IDM01 via MIDI. If you have only one IDM01, you can skip this section.

1. The source IDM01 should be in User Pattern mode and stopped. Connect the source IDM01 MIDI
out to the destination IDM01 MIDI in.

2. Select the Pattern to be copied.

3. Press and hold the COPY button, and keep holding it down until step (5). The display says COPY TO
PATT.

4. Do not enter any destination Pattern number—just press PLAY to send the data out over MIDI. The

display says PATT OUT MIDI. The source IDM01's Pattern will end up in the receiving IDM01's
currently selected Pattern location.

• This procedure follows the standard copy rules described at the beginning of section 3.3.

• If the receiver was set to Main, and the Pattern is not empty, the source Main and Fill Patterns will be
appended to the receiver's Main and Fill Patterns.

• If the receiver was set to Fill, the Fill will replaced by that of the source Pattern to maintain the same
Main and Fill Pattern lengths.

5. Release the COPY and PLAY buttons.

3.3E Copy a Single Drum Pad's Part to a Drum Pad in Another IDM01 Via MIDI

The IDM01 can send system exclusive information for a drum part to another IDM01 via MIDI. If you
have only one IDM01, you can skip this section.

This copy function merges the source drum pad rhythm with the destination drum pad rhythm in
another IDM01. To replace the destination rhythm with the source rhythm, first erase the destination
pad rhythm to be replaced (section 3.2C).

1. The source IDM01 should be in Pattern mode and stopped. Connect the source IDM01 MIDI out to
the destination IDM01 MIDI in.

2. Select the Pattern containing the drum part to be copied.

3. Press and hold the COPY button, and keep holding it down until step (7).The display says COPY TO
PATT.

4. Tap the pad containing the part to be copied. The display will show the drum number (for example,
D2 if you hit pad 2).

5. Tap the destination pad on the destination IDM01 to which the source part will be merged. Often

when copying to a different Pattern, this will be the same drum pad number as selected in step (4). As
long as COPY is held down, the destination pad can still be changed by selecting another drum pad.

6. Press PLAY. The display says DRUM OUT MIDI.

7. Release the COPY and PLAY buttons.

26

3.3F Copy a Drum Set to Another IDM01 Via MIDI

The IDM01 can send Drum Set system exclusive information to another IDM01 via MIDI. If you have
only one IDM01, you can skip this section.

1. The source IDM01 should be in Pattern mode and stopped. Connect the source IDM01 MIDI out to
the destination IDM01 MIDI in.

2. Select the Drum Set to be copied.

3. Press and hold the COPY button, and keep holding it down until step (5).

4. Press DRUM SET to send the data out over MIDI (the display says SET OUT MIDI).

5. Release the COPY and PLAY buttons.

The current Drum Set parameters, including changes you may have made, will reside in the
destination IDM01's Drum Set memory buffer. To save the Drum Set, you must save it to a

user Drum Set memory location in the destination IDM01. Its display will show DRUMSET
EDITED to remind you that the Drum Set needs to be saved.

27

CHAPTER 4: CREATING DRUM SETS

The IDM01's 12 pads can be assigned to various drum sounds, with different levels, tuning,
panning, triggering mode, and output jack assignment. Each set of pad parameters is given a
number and collectively are called a Drum Set; each A and B user Pattern can have its own
Drum Set assignment. There are 50 preset Drum Sets and 50 user-programmable Drum Sets.
Drum Set assignments have their own dedicated memory and can be thought of as equivalent
to the "programs" or "patches" found in synthesizers.

Note that if you edit a Drum Set, any Pattern using that Drum Set will be affected. Most IDM01
aficionados keep a one-to-one correspondance between Drum Sets and Patterns by assigning
Set 00 to Pattern 00, Set 01 to Pattern 01, Set 02 to Pattern 02, etc.

General instructions for Drum Set construction are:

1. Press the DRUM SET button.

2. Use the Page (up and down) buttons to select different "pages" of functions; the display's

lower right window shows the page number. These pages are described below.

3. Adjust values on pages, if necessary, as described for each page.

4. After making all needed changes, save the Drum Set if desired (Page 8), then press DRUM

SET again to exit (or choose another page).

4.1 PAGE 1: SELECT DRUM SET (DRUMSET SELECT)
The display shows DRUMSET SELECT, the currently selected Drum Set number, and whether

the Preset or User Drum Set bank is currently selected.

1. Press the PRESET/USER button to choose the desired bank of Drum Sets.

2. Enter the desired Drum Set number (from 00 to 49) with the number or INC/DEC buttons.

With the number buttons, enter a leading zero if necessary.

3. User Patterns will remember the selected Drum Set assignments (Preset Patterns have
fixed Drum Set assignments; if you exit from the Preset Pattern, the IDM01 will forget any
assignment you made).

You can assign any of the IDM01's sounds to any of the pads, or to more than one pad. Each
individual Drum Set can have its own drum sound assignment.

To assign a sound to a pad:

1. Press the pad (the display will show the pad number).

2. Enter the desired drum sound number with the number or INC/DEC buttons. When using the

number buttons, enter a leading zero if necessary. The chart included with the IDM01

To change the pan position associated with a given pad:

1. Press the pad (the display will show the pad number).

2. Enter the desired pan position, from full left to full right, using either the number or INC/DEC

buttons. The seven available pan positions correspond to the number buttons shown in
parenthesis: hard left (1), soft left (2), left of center (3), center (4), right of center (5), soft right
(6), and hard right (7).

3. When the display confirms your choice, either store the edited Drum Set (see section 4.8) or
do more assignments by tapping another pad to select it, then assigning the pan position.

Background The IDM01 has two pairs of stereo outputs. Drum sounds can be assigned to either pair of outputs
(Page 7), and be placed anywhere within the stereo field of the assigned outputs via the pan function.

When heard from the drummer's perspective, the high-hat will usually be on the left, snare and kick in the center,
and toms trailing from left-center to right. Of course, one of the advantages of electronic drum sets is that you
need not follow any standard way of placing drum sounds in the stereo field.

3. When the display confirms your choice, either store the edited Drum Set (see section 4.8) or

do more assignments by tapping another pad to select it, then changing the new assignment
mode.

Background Each mode affects triggering in a different way:
Multi: When hitting a pad repeatedly, each hit will cause the sound to go through its entire decay. This is useful

with cymbals, since early strikes will continue to decay as you play later strikes.
Single: When hitting a pad repeatedly, a new hit will automatically terminate any sound that is still decaying. This

is useful with many percussion sounds (such as tambourine, agogo, etc.).
Group 1 and 2: Pads assigned to a particular group (1 or 2) will cut each other off if a group pad is struck while

another pad assigned to the same group continues to sound. The classic use of this is with hi-hats; a closed high­hat will cut off an open hi-hat, and hitting an open hi-hat sound will cut off a closed hi-hat.

The IDM01 can play up to 16 voices at a time, so it's possible to run out of voices if you play a flurry of notes and
have lots of pads in the Multi assign mode. If 16 sounds are playing and you ask the IDM01 to play another one,
the sound that's closest to finishing its decay cycle will be "stolen" so that the most recent sound can be played. In
practice, it's difficult (and usually not artistically desirable!) to create drum parts so complex that voice-stealing
becomes a problem. However, if this is a problem, try assigning all the toms to a group so that they only require
one voice at a time.

4.7 PAGE 7: CHOOSE OUTPUT JACKS (OUTPUT)
The display shows OUTPUT, the currently selected pad number, and the pad's output

assignment.

To change the output assignment:

1. Press the pad (the display will show the pad number).

2. Use the INC/DEC buttons or number buttons (1 chooses the Main output pair, 2-0 the Aux

output pair).

3. When the display confirms your choice, either store the changes you've made (see section

4.8) or do more assignments by tapping another pad then entering its new output assignment.

Background The IDM01 includes two independent stereo output pairs (Main and Aux). You can direct any pad
to either output pair, and pan the sound within the selected output's stereo field (section 4.4). This allows several
output assignment options:

32

DRUMSET

PAGE

Mono: Plug into one of the output pair jacks; the IDM01 is smart enough to know that plugging in one plug means
you must want mono. Any pan settings are ignored. Do not plug into both outputs, or stereo will be activated.

Stereo with Fixed Placement: Plug the left Main output into the left channel of your amp (or mixer), and the right
Main output into the right channel. The default voice mix for the preset Drum Sets pans the drums between the
Main output jacks in a way that works well for most applications.

Stereo with Variable Placement: Plug the left Main output into the left channel of your amp (or mixer), and the
right Main output into the right channel. With the User Drum Sets, you can pan the drums between the Main
output jacks as desired.

Stereo with Individual Outputs: This requires a stereo mixer with at least four channels, and provides individual
outputs for any two drum voices. Plug the left Main out into a mixer channel panned fully to the left. Plug the right
Main out into a mixer channel panned fully to the right. Plug the left Aux output into a third channel (panned to
center for now) and the right Aux output into a fourth channel (also panned to center for now). Decide which two
voices should be individual voices, such as kick and snare; assign these to the Aux outputs, and all other drums
(panned as desired) to the Main outputs.

Pan the kick full left and the snare full right. Thus, the kick will appear in the left aux output, and the snare will
appear in the right aux output. These outputs can feed different signal processors and then sent to a mixing
board. Make sure that the drums selected for individual outputs are panned to the extreme left or right in the
IDM01. Otherwise, some of the sound from one drum will leak into the other output.

Separate Percussion/Drum Outputs: Standard drum kit sounds can be spread in stereo and assigned to the main
outputs, with percussion sounds spread in stereo and assigned to the Aux outputs. Run the outputs to a mixing
console, and you can treat the drum kit and percussion sounds as two submixes. This technique might also be
useful if you're recording the part on tape; feed the drums to two tape tracks, and the percussion to two other
tracks. Adjust the balance between the two in the mix, or fade the percussion in and out independently of the trap
drum sounds. Or, process the two groups individually.

If you were editing a Preset Drum Set and want to save it, you will be given the option to save
it to a User Drum Set since you cannot overwrite a Preset Drum Set. This technique can also
copy one Drum Set to a different Drum Set. Also, remember that if you change Patterns
before saving your Drum Set, all of your edits will be lost.

4.9 PAGE 9: MANUAL DRUM SET OVERRIDE (SET MODE)

The display says SET MODE. Use the INC/DEC buttons to select PATT (each Pattern uses its
assigned Drum Set) or MANUAL (the IDM01 will retain the currently selected drum
assignments regardless of which Pattern is chosen).

SET MODE

Note: If changing Patterns doesn't call up different Drum Sets, this parameter is probably set to
MANUAL instead of PATT.

Background Each Pattern has an associated, assigned Drum Set. However, you can tell the IDM01 to ignore
these stored assignments, and retain the currently selected Drum Set regardless of whether or not you change
Patterns. This is useful if you want to hear how a Pattern would sound with a different Drum Set (just set one up
manually) as opposed to the one stored with the Pattern.

CHAPTER 5: SONG MODE

5.1 SONG MODE BASICS

After creating the Patterns that make up a Song, it's time to string those Patterns together in a
musically useful way. You can incorporate Preset Patterns, or a combination of Preset and
User Patterns. There are three ways to create Songs:

• In real time. As the IDM01 plays in Song Mode (with Compose mode selected), it will
remember the Patterns and Fills you select.

• Manually. Select Song mode and program a list of Patterns and Fills in the order in which the
Patterns are to be played. You can specify the beat and sub-beat on which the Fill takes over
from the associated main Pattern.

• A combination of real time and manual recording. Create a Song in real time, then edit it
manually to insert extra Song steps, delete Song steps, etc.

The IDM01 holds up to 100 Songs, and each Song can contain up to 254 steps. Each step
holds either a Pattern number or Fill. Each Song remembers the tempo at which it was last
played.

5.1A Select Songs and Enter/Exit Song Mode

1. The IDM01 should be in Song mode.

2. Select PERFORM mode.

3. Enter a two-digit Song number with the number or INC/DEC buttons. Song numbers must

always include two digits; enter a leading zero if necessary.

4. Press PLAY to begin playback. Press STOP to stop playback.

5. To exit Song mode and return to Pattern mode, first stop the Song with the STOP button,

then press the PATTERN/SONG button.

5.1B Set Song Tempo

The tempo range extends from 20 to 255 beats per minute. Song tempo can be changed while
the IDM01 is stopped or running, and the Song remembers the last tempo that was chosen.
There are two ways to set tempo.

1. Before pressing PLAY to start a Song, tap the STOP button several times at the desired
tempo. The IDM01 will average the time between taps and derive a tempo; the display will
update the tempo with each tap. If a footswitch is plugged into the Count/A/B/Fill jack, tapping
the footswitch at the desired rate is equivalent to tapping the STOP button. These techniques
work only if the IDM01 is stopped.

2. Use the TEMPO/PAGE up and down buttons. Press once to increment/decrement
respectively 1 BPM at a time, or press and hold to scroll through the tempo values.

35

Background While in Pattern mode, the tempo remains as is until changed. If you switch over to Song mode
and the programmed Song tempo is different, the IDM01 will assume the Song's tempo—even if you switch back
into Pattern mode—until the tempo is changed again (either manually, or by selecting a different Song).

5.1C Continue, Re-start, or Jump to Next Song Step

• In Compose mode, if you stop a Song and then press PLAY, the Song will continue from the
first beat of the Pattern that was playing when STOP was pressed.

• In Perform mode, if you stop a Song and then press PLAY, the Song will re-start from the
beginning.

• In either Compose or Perform mode, press PLAY while the Song is playing to immediately
jump ahead to the next Song step. Its associated Pattern will begin on the downbeat. This is a
convenient way to "fast forward" over certain parts of a Song.

5.1D "Loop" a Pattern Indefinitely

In Song Perform mode, pressing and holding FILL until the end of a song step will cause that
step to repeat. A footswitch plugged into the Count/A/B/Fill jack will perform the same function.

Examples: Use this feature if a soloist decides to take another few bars. Another use is if two
Songs share the same tempo. Follow the first Song with a blank Pattern, then append the
second Song. Between Songs, hold down the footswitch on the blank Pattern song step, then
release to start the second Song.

5.1E Start from the Middle of a Song

You need not start a Song from the beginning each time; in Compose mode, a Song can start
at any Song step.

1. Make sure the IDM01 is in Compose mode, even if you don't plan to record anything.

2. Use the INC/DEC buttons to select the Song step at which you want the IDM01 to start

playing.

3. Press PLAY. The IDM01 will start playing at the downbeat of the selected Song step.

4. If you don't want to extend the Song length, go into Perform mode before reaching the end

of the Song. If you do want to extend the Song length, remain in Compose mode.

5.1F Name a Song (NAME)

1. The IDM01 can be in either Compose or Perform mode.

2. Press RECORD SETUP. If the Song has been named, the name will show on the top line. If
the Song has not been named, the display says NO NAME.

3. Enter the name using the PAGE UP/DOWN buttons to select the character to be changed,

and the INC/DEC buttons to select the desired character. Lower case and upper case letters,
numbers, punctuation, and various special-purpose characters are available. You can also
enter numbers with the number buttons.

36

5.1G Change Song Tempo as the IDM01 Plays

To change the Song tempo as it plays, press the TEMPO/PAGE UP button to increase the
tempo, and the TEMPO/PAGE DOWN button to decrease the tempo.

5.2 REAL TIME SONG CREATION

To create a Song in real time (this assumes an empty song):

1. (Optional) In Pattern mode, select the Pattern you want for the first Song step.

2. Select Song mode and the desired Song number.

3. Select Compose mode. The display will show STEP 01 and the contents of the step, which is

currently END (if the first step says END, that indicates that the Song is empty since it contains no data.
If the first step shows a PATTern number, then the Song is not empty).

4. If you did not perform step (1) above, enter the desired Pattern for step 1 (Preset or User, A or B, A
Fill or B Fill).

5. Press PLAY. If you performed step (1) above, the Pattern you selected will begin playing. Otherwise,
the Pattern specified in step (4) above will start playing.

6. If you enter a new Pattern number (Preset or User, A or B) while the first Pattern is playing, the new
Pattern will begin playing after the first Pattern has finished and be stored as another Song step in the
Song. If you let the original Pattern keep playing, it will add a new Song step with its Pattern number
every time it repeats.

7. In addition to selecting different Patterns, you can press FILL at any time. The IDM01 will remember
where you pressed FILL.

As in Pattern mode, pressing FILL will automatically transition to the B Pattern if the A Pattern is
currently playing (and vice versa), or will continue playing the same Pattern if the FILL button is held
past the end of the Fill.

A Fill can transition into any Pattern number, A or B, by specifying the Pattern before the end of the Fill
and releasing FILL before the Fill has finished playing. If you hold FILL past the end of the Fill, the
associated Main Pattern will continue playing and any Pattern you may have previously specified for
the next Step will be forgotten.

When recording a Song in Compose mode, the Count/A/B/Fill footswitch duplicates the FILL button
function.

5.2A Real Time Song Editing

If you have already recorded material in a Song, pressing PLAY while in Compose mode will
not allow recording until after the last Song step (as indicated by the display switching from
PLAYING to RECORDING). However, you can overdub Fills at any time, and these will be
recorded in the Song where played. Under these conditions, holding FILL past the downbeat
doesn't make any difference; the Patterns used in Song steps are not altered.

37

5.3 MANUAL SONG CREATION

5.3A Enter a Pattern

1. Select Song mode and the desired Song number.

2. Select Compose mode. The display will show STEP 01 and the contents of the step, which

is currently END (if the first step says END, that indicates that the Song is empty since it
contains no data. If the first step shows a PATTern number, then the Song is not empty).

3. Enter a two-digit Pattern number with the number buttons. If desired, choose between the
A/B variations and Preset/User options.

4. If you want to enter another Pattern, press the INC button to move to the next step; or press
the DEC button to return to a previous step and change its Pattern.

5.3B Add a Fill

1. With the IDM01 in Song and Compose modes, select the step where the Fill is to be added.

2. Press and hold the FILL button.

3. Enter the number of beats and sub-beats after the start of the current step in which the Fill is

to start playing with the number buttons and INC/DEC buttons respectively. It is not necessary
to press PLAY; the step will remember where the Fill is to occur.

4. As the Song plays the step where the Fill occurs, the display will show FILL when the Fill
begins playing.

5.3C Remove a Fill

While in Compose mode, there are two ways to remove a Fill from a Song:

• When the Fill step appears, press the A button for an A Pattern or press the B button for a B
Pattern and the Fill will be removed.

• When the Fill step appears, press and hold the FILL button and press ERASE.

5.3D Insert a New Step Between Two Existing Song Steps

1. The IDM01 should be in Song and Compose modes.

2. Use the INC/DEC buttons to select the step number that the inserted step should occupy.

Example: To insert a step after step 04, select step 05.

3. Press and hold COPY, and keep holding it down until step (6). The display says INSERT.

4. Enter the two-digit Pattern number to be inserted.

5. Press PLAY. The new step is inserted, and all subsequent steps are automatically re-

numbered to reflect the addition of the inserted step (e.g., what used to be step 05 is now step
06, what used to be step 06 is now step 07, etc.).

6. Release the INSERT and PLAY buttons.

38

5.3E Delete a Step

1. The IDM01 should be in Song and Compose modes.

2. Use the INC/DEC buttons to select the step number to be deleted.

3. Press and hold ERASE. The display says ERASE STEP?

4. While continuing to hold ERASE, press PLAY. The step is deleted, and all subsequent steps

are automatically re-numbered to reflect the deletion of the inserted step (e.g., what used to
be step 06 is now step 05, what used to be step 07 is now step 06, etc.). The display says
STEP ERASED for as long as the ERASE and PLAY buttons are pressed.

5. Release the ERASE and PLAY buttons.

5.3F Replace a Step

1. The IDM01 should be in Song and Compose modes.

2. Use the INC/DEC buttons to select the step number to be replaced.

3. Enter the new Pattern number (with appropriate A or B, Fill, or User/Preset options). Since

the step is replaced, no renumbering of subsequent steps occurs.

5.3G Erase an Entire Song

1. The IDM01 should be in Song and Perform modes.

2. Use the number buttons to select the Song to be erased.

3. Press and hold the ERASE button. The display says SONG ERASE?

4. While holding down the ERASE button, press PLAY. The display says SONG ERASED and

erasure is complete.

5. Release the ERASE and PLAY buttons.

5.3H Copy a Song to Itself (Double Song Length)

Copying a Song to itself doubles the Song's length.

1. The IDM01 should be in Song and Perform modes.

2. Select the Song to be copied to itself with the number or INC/DEC buttons.

3. Press and hold the COPY button. The display says COPY TO SONG .

4. While continuing to hold the COPY button, enter the same Song number as the one

selected in step (2) and press PLAY. The copy is complete, and the display says COPY
DONE.

5. Release the COPY and PLAY buttons.

5.4I Copy a Song to Another Song (or to the End of Another Song If That Song is Not Empty)

1. The IDM01 should be in Song and Perform modes.

2. Select the Song to be copied with the number or INC/DEC buttons.

39

3. Press and hold the COPY button, and keep holding it down until step (6). The display says

COPY TO SONG with the number of the currently selected Song.

4. While continuing to hold the COPY button, enter the destination Song number to which the

source Song should be copied using the number or INC/DEC buttons.

5. While you continue to hold the COPY button down, press PLAY. The copy is complete, and
the display says COPY DONE.

6. Release the COPY and PLAY buttons.

Notes

• If the destination Song was empty, the copy is identical to the source Song.

• If the destination Song was not empty, then the source Song is appended to the end of the destination Song.
This increases the destination Song's length by the length of the source Song; if the total destination Song length
would exceed 254 steps after copying, the copy will not take place, and the display will say SONG TOO LONG.

5.4J Copy a Song to Another IDM01 Via MIDI

The IDM01 can send Song system exclusive information to another IDM01 via MIDI. If you
have only one IDM01, you can skip this section.

1. The source IDM01 should be in Song mode and stopped. Connect the source IDM01 MIDI
out to the destination IDM01 MIDI in.

2. Select the Song to be copied.

3. Press and hold the COPY button, and keep holding it down until step (5). The display says
COPY TO SONG.

4. Do not enter any destination Song number—just press PLAY to send the data out over

MIDI. It will end up in whatever Song number had been selected at the receiver. If the Song
was not empty, the new Song steps will be appended to the existing Song steps.

5. Release the COPY and PLAY buttons.
Caution: This does not transfer Pattern information, only the song steps. To transfer Patterns

to another IDM01, see section 3.3D and 3.3E.

CHAPTER 6: MIDI SETUP

This menu accesses important MIDI functions. General instructions are:

1. Press the MIDI SETUP button.

2. Use the Page (up and down) buttons to select different "pages" of functions; the display's

lower right window shows the page number. These pages are described below.

3. Adjust values on pages, if necessary, as described for each page.

4. After making all needed changes, press MIDI SETUP again to exit, or choose another page.

All the parameters on the following pages remain as set, even if you turn off power, until
changed.

6.1 PAGE 1: SELECT MIDI CHANNEL (MIDI CH)

MIDI CH
O

SETUPMIDI

The display shows the MIDI CHannel (1-16) or Omni. Enter the desired value with the number
or INC/DEC buttons. (With the number buttons, enter a leading zero if necessary; 00 selects
Omni mode.)

Background The IDM01 can receive and transmit MIDI data in Omni mode (receives data appearing on any of
the 16 MIDI channels; transmits data over channel 1) or Poly mode (transmits and receives over any one of the
16 MIDI channels).

Use Omni when playing the IDM01 from an external MIDI controller (MIDI drum pads, MIDI keyboard, etc.) since
it's not necessary to match channels. When several instruments are being driven by MIDI (e.g., when a
sequencer sends out data over several channels to different instruments), use Poly mode so that the IDM01
tunes in to only the channel containing drum data.

6.2 PAGE 2: RECEIVE MIDI DRUM NOTES (DRUM IN)

DRUM IN

SETUPMIDI

PERFORM

The display shows DRUM IN. This page features two different MIDI input velocity curves (ON
V1 and ON V2). To have the IDM01 receive note messages at its MIDI input, use the

INC/DEC buttons to select ON V1 or ON V2. Select OFF to have the IDM01 ignore note
messages. ON V1 is a normal linear velocity curve, and will not affect MIDI velocity data being
sent by the controller. For keyboards that do not provide a full range of velocity, ON V2 will
allow the drums to be played at full volume without having to send full velocity from the MIDI
controller.

Background Select ON V1 or ON V2 if you're using the IDM01 as an expander module, or want to play real time
drum controllers into the IDM01 as it plays a Pattern or Song. Select OFF if you're using the IDM01 as a drum
machine slaved to a sequencer; when OFF, the IDM01 follows the sequencer timing data but not note data (you
don't want it to play other parts). Note that Clock In (page 5) must be on.

6.3 PAGE 3: TRANSMIT MIDI DRUM NOTES (DRUM OUT)

PAGE

SETUPMIDI

The display shows DRUM OUT. To have the IDM01 output MIDI note data from pad hits or
when playing a Pattern/Song, use the INC/DEC buttons to select ON. Select OFF if you don't
want the IDM01 to transmit note data.

Background Select ON to send Pattern data into a sequencer for recording, or drive other drum sound expander
modules. If the IDM01 is acting as a drum machine and provides the master clock to a MIDI system, select OFF
so that other devices don't respond to the MIDI note data.

6.5 PAGE 5: ACCEPT EXTERNAL CLOCK DATA (CLOCK IN)

CLOCK IN
O

SETUPMIDI

The display shows CLOCK IN. To have the IDM01 recognize clock (timing) messages present
at its MIDI input, use the INC/DEC buttons to select ON (if no clock messages are present, the
IDM01 will follow its internal clock tempo). Select OFF to have the IDM01 ignore clock
messages and follow its internal clock tempo regardless of what timing data appears at the
MIDI in.

When using the IDM01 as an expander module, set CLOCK IN to OFF so that timing signals
don't start playing a Pattern.

Background The IDM01 can have its tempo set by another device (this overrides the internal clock tempo) if:

• The external device (sequencer, drum machine, etc.) generates MIDI timing signals.

• These signals go from the external device's MIDI out to the IDM01's MIDI in.

• CLOCK IN is ON.

PAGE

Background The IDM01 can generate timing signals to which other devices can synchronize if:

• The external device (sequencer, drum machine, etc.) can respond to MIDI timing signals.

• These signals go from the IDM01's MIDI out to the external device's MIDI in.

• CLOCKOUT is ON.
When slaving the IDM01 to other devices, CLOCKOUT should be OFF and CLOCK IN should be ON.

6.7 PAGE 7: MERGE MIDI IN WITH MIDI OUT (MIDITHRU)

MIDITHRU
OFF

SETUPMIDI

PERFORM

The display shows MIDITHRU. To have the IDM01 merge data appearing at the MIDI in with
the timing and/or note data appearing at the MIDI out, use the INC/DEC buttons to select ON.
Select OFF to have the IDM01 MIDI out carry IDM01 timing and note data only.

Background Turning MIDI out to MIDI thru can be handy for some system applications. Example: Assume a
MIDI keyboard connects to the IDM01 MIDI in. The IDM01 serves as the master clock for an MMT-8 sequencer;
the IDM01 MIDI out connnects to the MMT-8 MIDI in. With MIDITHRU set to ON, the keyboard note data will be
passed through the IDM01 and appear at the MMT-8 MIDI in.

Other IDM01 settings should be DRUM IN OFF (so the IDM01 doesn't respond to your keyboard playing) and
CLOCKOUT ON so that the IDM01 clock drives the MMT-8. DRUMOUT should also be OFF so that the MMT-8
doesn't record the IDM01 drum notes. Plugging the MMT-8 MIDI out to the keyboard MIDI in plays back the
sequenced notes through the keyboard.

Technically speaking, MIDI timing data (as provided by a master unit such as a sequencer) received at the
IDM01's MIDI in is not sent to the MIDI out. However, this will appear to be the case since the IDM01 will
generate its own timing data in response to the timing data received at its MIDI in, if CLOCK IN and CLOCK OUT
are both ON.

6.8 PAGE 8: SELECT DRUM SETS VIA MIDI PROGRAM CHANGES (PRG CHNG)

PRG CHNG
O

SETUPMIDI

FF

The display shows PRG CHNG. Program Change commands can change Drum Sets numbers
at any time, including while the IDM01 is playing. To have the IDM01 receive Program
Changes, use the INC/DEC buttons to select ON. Select OFF to have the IDM01 ignore
Program Changes.

Background Program Change (PC) 00 selects User Drum Set 00; PC 01 selects User Drum Set 01; PC 02
selects User Drum Set 02; etc. Caution! Some units number Program Changes as 1-128, others as 0-127, and
some as banks of programs. If the device generating Program Changes follows a non-standard protocol, it's a
good idea to make up a conversion chart that shows which Program Changes call up which Drum Sets.

Program Changes 00-49 select the 50 User Drum Sets. Program Changes 50-99 select Preset Drum Sets 00-49.
Program Changes 100-127 select User Drum Sets 00-27.

The current Pattern will remember whatever Drum Set is selected via Program Changes, just as if you had
selected it manually, unless the IDM01 is in Manual mode (described in Page 9 of the Drum Set menu).

If Program Change is enabled, and the IDM01 is in MULTI-DRUMSET mode (see section 6.9 below), and a
program change is received in the 00-49 range, the IDM01 will automatically select the drumset group
corresponding to the program change number. For example, if program 36 is received with the above conditions
met, the note map will change to drumset group 30-39.

6.9 PAGE 9: MAP DRUM NOTES (NOTE MAP)

Within each Pattern, MIDI notes can either be mapped to 12 different sounds in NORMAL mode,.or
they can be mapped to any of five drumset groups (User Drumsets 00-09, 10-19, 20-29, 30-39, and 40-

49) in MULTI-DRUMSET mode. Any of these drumset groups can cover MIDI notes 000 through 119.
This makes the IDM01 ideal for use as a drum sound module, triggered by either an electronic drum kit
or set of electronic drum pads, or by notes from a sequencer.

Note that while in this mode, you cannot record notes into a Pattern via MIDI. It is assumed that you will
be using the IDM01 strictly as a drum sound expander module.

The chart on the following page shows which drum pads of which drum sets are triggered by which
MIDI notes. The logic to this assignment is that there are 12 drum pads per octave of notes, so pad 1
always starts on a C note (MIDI notes 000, 012, 024, 036, 048, 060, 072, 084, 096, and 108).
Remember that these drum assignments must be saved as Drum Sets in order to retain the note map
assignments.

CHAPTER 7: BACKUP

7.1 BACKUP BASICS
This function allows you to save the IDM01 Pattern, Song, and Drum Kit data to cassette tapes

or MIDI system exclusive storage devices. General instructions are:

1. Press the BACKUP button.

2. Use the Page (up and down) buttons to select different "pages" of functions; the display's

lower right window shows the page number. These pages are described below.

3. Adjust values on pages, if necessary, as described for each page.

4. After performing the desired backup operation, press BACKUP again to exit, or choose

another page.
With all tape operations, pressing STOP during a data transfer cancels the operation from that

point on, as indicated by the display (TAPE OUT CANCEL when saving, TAPE IN CANCEL
when verifying or loading). If you press STOP during a load from tape, the memory contents
may end up partially full, thereby resulting in jumbled data for some Patterns or Songs.
However, if you're loading a single Pattern or Song, you can press STOP any time after the
desired Pattern or Song has loaded.

If an error occurs while loading, the display will say ERROR; loading continues but the data
may be unuseable. Try reloading an alternate take of the data. If the tape stops or a dropout
lasts long enough for the IDM01 to think the tape has stopped, the transfer will be cancelled
(the display says TAPE IN CANCEL).

Background The IDM01 can save the data in memory by converting this data into audio tones and recording
these tones on a standard audio tape machine (usually cassette). Data can also be converted into a special type
of MIDI code and stored in a MIDI data storage device such as the Alesis DataDisk, or transferred to another
IDM01. As you build up a library of Patterns and Songs, data can be reloaded from tape or MIDI into the IDM01.
There are two main reasons to save your work:

• Although the IDM01 can typically store over 15,000 events, eventually it will run out of memory. You can save
the memory contents, fill up the memory with new Patterns and Songs, and re-load the old data when needed.

• It is vitally important to back up what's in the IDM01's memory! A mechanical problem (surge on the power
line, a quick zap of static electricity) or operator error could alter the data in memory. Save your data whenever
you've done enough work on something that you wouldn't want to lose that work. If possible, make two backups,
and store the second backup in a different physical location from the primary backup.

Caution! Saving and loading data is very unreliable when done incorrectly, and very reliable when done right. To
promote error-free saves and loads, use a high-quality recorder and tape.

48

7.2 TAPE INTERFACE HOOKUP
To save to tape: Connect a mini phone plug cable (male-to-male) from the IDM01 tape in/out

to the recorder's tape in. If you are using a standard cassette recorder rather than a data
recorder, plug into the recorder's Aux or Line Level input. If your only option is to plug into the
microphone input, you may still be able to achieve satisfactory results.

7.3 PAGE 1: SEND DATA AS MIDI TO A MIDI SYS EX STORAGE DEVICE (SEND OUT MIDI?)

The display shows SEND OUT MIDI? To convert the IDM01's Pattern and Song information
into MIDI system exclusive data and send this data through the MIDI out, press the PLAY
button. The display will say SENDING MIDI… to confirm that data is being sent. Typically, the
MIDI out would connect to another IDM01's MIDI in or a system exclusive data storage device
such as the Alesis DataDisk. The IDM01 data can take up as much as 35K, allowing it to be
captured by most system exclusive storage devices.

After the transfer is complete, the IDM01 display reverts to either Song or Pattern mode
(whichever had been selected prior to saving).

49

Background The IDM01's memory contents can be sent out over MIDI like any other MIDI data. This data is
meaningful only to an IDM01 (different drum machines will ignore the data) but the data can be saved to a MIDI
system exclusive storage device, such as the Alesis DataDisk, a computer running System Exclusive storage
software, or a musical instrument capable of recording System Exclusive data (Yamaha SY77 and DX7IIFD,
Ensoniq EPS and VFX, Peavey DPM-3, etc.). This function also lets you send all Patterns, Songs, and Drum
Setups to another IDM01 without having to save to tape first.

The following describes how to save data to the Alesis DataDisk; other system exclusive storage devices work
similarly, but please refer to the owner's manual for your particular device to find out how to set it up to accept
and store MIDI data.

Saving to DataDisk

1. Connect the IDM01 MIDI out to the DataDisk (DD) MIDI in.

2. Insert a formatted disk into the DD and proceed to the next step. If the disk is not formatted, insert it in the drive

and press the DD Format switch. When the DD display says FORMAT DISK?, press DO/YES. When the display
says ARE YOU SURE? press DO/YES again.

3. Press the DD RECEIVE button. The display says RECV ONE SYSEX: WAITING FOR DATA.

4. Press the IDM01 BACKUP button (if you are not already in the backup function) and select Page 1.

5. Press the IDM01 PLAY button. The IDM01 display says SENDING MIDI… and the DD display says

RECEIVING ION IDM01 to indicate that data has been received.

6. To prevent future confusion, name the DD file using the DD NAME function.

7.4 RECEIVE DATA DIRECTLY FROM ANOTHER MIDI DEVICE

The IDM01 will automatically load IDM01 system exclusive data present at its MIDI input.
Therefore, there is no associated function page since reception can occur at any time that a
sys ex storage device or another IDM01 sends data through its MIDI out into the IDM01's MIDI
in. If the IDM01 receives sys ex while a Pattern or Song is playing, the Pattern or Song will
stop. Song 99 will be selected once the dump is finished.

The IDM01 is compatible only with IDM01 system exclusive data; for example, you cannot load
system exclusive data from another drum machine into the IDM01.

The following describes how to load data from the Alesis DataDisk; other system exclusive
storage devices work similarly, but please refer to the owner's manual for your particular
device to find out how to set it up to send MIDI sys ex data.

NOTE: When loading a single drum set in sys ex, be sure and save the set to a user drum set
memory location before changing patterns. If you change Patterns before saving the drum set,
the drum set will be lost.

Loading from DataDisk

1. Connect the DD MIDI out to the IDM01 MIDI in.

2. Insert the disk into the DD that contains the file to be loaded into the IDM01.

3. Press the DD SEND button. The display says SEND FILE ION IDM01 (filename)?

4. Press the DD DO/YES button. The IDM01 automatically senses the presence of this data; no button-pushing is

required. The DD display says SENDING: ION IDM01 (filename), the IDM01 display says LOADING MIDI. Note
that loading sys ex data overwrites all existing IDM01 memory.

5. The IDM01 will now be set to Song 99.

This function saves all Patterns, Songs, and Drum Kits to tape. The display shows STORE TO
TAPE? Put the cassette recorder into record mode. After the tape has gone past the leader (if

present), press PLAY on the IDM01. The IDM01 display will increment through the A/B
Patterns and Songs; the operation is finished when the display says DONE. It's a good idea to
save data several times in case part of the tape becomes damaged.

To cancel the saving operation at any time, press STOP. The display says TAPE OUT
CANCEL.

Remember that you can save data to any tape medium. For example, recording drum part data
at the head of a multi-track master is often convenient, as it stores the drum parts used on a
song with that song.

Background Although cassette interfaces are quite reliable, problems can occur due to incorrect tape levels,

defective tape, bad luck, etc. Do not consider your work as saved until you have verified the data recorded on
tape, thus insuring that it can be loaded back into the IDM01 in the future.

Unlike some other cassette interfaces, this function verifies that the data on tape is valid, not necessarily that it's
the same data as what's in the machine. In other words, the verify function does not work by checking the tape
data and IDM01 data for similarities. Therefore, you can verify tape data at any time.

FREE MEM
100%

BACKUP

When you select Page 7, the display will show the approximate amount of free memory
available (expressed as a percentage of the total amount).

Background It is important to check memory from time to time because the IDM01 always requires some free
memory for proper operation. If the available memory falls below 15% or so, immediately save the IDM01's data
as previously described in this chapter.

Some operations may not be possible even if a small amount of memory is left. This is because the IDM01
duplicates a Pattern before it is modified (length change, offset change, etc.). If you try to alter a Pattern that
takes up more memory than is available, the display will tell you that there is no more memory left.

Immediately save the IDM01's data, and determine whether you can erase any unwanted Patterns or Songs to
free up some memory.

7.11 CLEAR MEMORY/RE-INITIALIZE PARAMETERS

After saving a bank of data, you may want to start programming new Patterns from scratch so
you don't mix up new Patterns with old ones. This operation clears the memory and re­initializes all parameters. It can also be a useful service technique to restore the IDM01 to
normal operation if it "locks up" due to some unforeseen event like a static electricity jolt or
power supply interruption.

All existing Patterns, Songs, and drum assignments will be lost when you clear memory. Save
the IDM01's memory to tape or MIDI unless you are absolutely sure you don't need it.

To re-initialize, turn off power and wait a few seconds. Press and hold the PLAY and ERASE
buttons while turning on power. Continue holding these buttons down for at least three
seconds after turning on power.

7.12 CHECK SOFTWARE VERSION

VERSION

To determine the software version in your IDM01, press the FILL button at any time you're in
the Backup menu. The display will show VERSION and the current software number.

Background There are two main reasons why it's important to know the software version.

• It is possible that the IDM01's operating system software may undergo changes or other enhancements at some
point in the future. This will let you know whether you have the enhanced software or not.

• Should you experience problems with the IDM01 and call ION for technical support, it is important to know which
software your machine is using.

CHAPTER 8: APPLICATIONS

8.1 MIDI SYNC APPLICATIONS

8.1A IDM01 As MIDI Timing Master

The IDM01 can control several other slave MIDI drum machines or sequencers by turning on
MIDI Clock Out, which sends IDM01 timing information down the MIDI line.

1. Turn on MIDI Clock Out (section 6.6).

2. Program the slave units to not follow their internal clocks, but to accept external MIDI Clock

and Start/Stop data. Refer to each device's manual to find out how to do this. Enable the
slave's Song Position Pointer if it is available (or it may be available all the time and not need
to be specifically enabled, as is the case with the Alesis HR-16 and MMT-8).

3. Press PLAY on the IDM01. The slave units should start at the same time, and progress at
the same tempo. If the slaves respond to Song Position Pointer, you can start an IDM01 Song
at any point, and after a few seconds the slaves will catch up and synchronize from that point
on.

The following diagram shows an IDM01 serving as the MIDI system master clock, with an HR­16 drum machine and MMT-8 sequencer set as slaves. Note that both devices must be set to
accept external MIDI clock messages.

8.1B IDM01 as MIDI Timing Slave

The IDM01 can slave to a MIDI master clock source by turning on Clock In. Example: This lets
you slave the IDM01 to a MIDI sequencer on which you have recorded other instruments.

1. Set the IDM01 Clock In to on (Section 6.5).

2. Make sure the master is set to generate MIDI timing data (refer to the unit's manual for

specific instructions on how to do this). Enable Song Position Pointer if necessary.

3. Press PLAY on the system master. The IDM01 should start at the same time, and progress
at the same tempo. If the master generates Song Position Pointer, you can start the master at
any point, and both units will synchronize from that point on.

The following diagram shows an IDM01 slaved to the MIDI system master clock, provided in
this case by a keyboard "workstation" on-board sequencer.

8.1C Synching to Synthesizer Sequencers

Many synthesizers include built-in sequencers (Ensoniq EPS16+ and VFX-SD, Roland D-20,
Korg M1 and T1, Peavey DPM-3, etc.). You can use the IDM01 as a drum expander module
and record the required notes in one of the sequencer tracks. Or, record a Song in the IDM01,
and sync it to the keyboard sequencer's timing data so you don't need to use up a sequencer
track.

8.2 STRATEGIES FOR ASSEMBLING PATTERNS AND SONGS

Ideally, you should be able to translate your inspirations into tangible form with a minimum
amount of effort. The following tips and techniques help speed up the process of creating
Patterns and Songs.

8.2A Create Fills Quickly with the Copy Function

Many times a Fill will simply be a variation on another Pattern, but with a few minor differences
to add variety or serve different musical purposes. To save time, use the Copy function to copy
the main Pattern to the Fill, then add variations to the Fill in real time or with Step Edit mode.

8.2B Assemble Short Patterns into Longer Patterns with the Copy Function

It's less time-consuming to work with short Patterns, since you don't have to wait for the entire
Pattern to cycle through before overdubbing or "spot erasing" events. After assembling several
short Patterns, use the copy function to append Patterns into a longer Pattern. Example:
Create four eight-beat Patterns, then use the copy function to combine these into a single 32­beat Pattern.

8.2C Save Memory Through Song Steps

Whenever possible, repeat Patterns using Song steps rather than program long Patterns.
Example: Suppose you have a 16-measure figure where the first three groups of four
measures are identical, and the final group of four measures provides some sort of variation.
Recording this as one 16-measure Pattern will take up more memory than recording two
Patterns (one of the first group of four measures and one of the last group of four measures),
and while in Song mode repeating the first group three times followed by the last group once.

8.2D Odd Time Signatures

For time signatures based on quarter notes, changing the number of beats in a Pattern can also
change the time signature. Example: Programming a Pattern length seven beats long will yield a
measure of 7/4. Programming a Pattern length 14 beats long will yield two measures of 7/4. Time
signatures such as 2/4, 3/4, 5/4, 9/4, and so on are easy to implement.

For time signatures based on eighth notes, it's easiest to double the tempo so that each beat lasts an
eighth note instead of a quarter note. However, you will have to take this into account when quantizing
and setting the metronome—if the display says a quarter note, read it as an eighth note.

Plan carefully when mixing odd time signatures within the same piece. If some Patterns use a time
signature based on quarter notes and others on eighth notes, you will need to double the tempo for the
quarter note-based Patterns to match up with the eighth-note based Patterns.

8.3 SOUND STACKING™

8.3A Basics

Sound Stacking™ was introduced by Alesis on its two earlier drum machines, the HR-16 and
HR-16:B. It is a quick and efficient way of layering drum sounds to create thicker drum textures
and gives the user wide capabilities for experimenting with new, personalized drum sounds.
Through some intelligent software manipulation, a drum sound's rhythm pattern can be copied
to any other drum pad thereby simultaneously triggering the drum sounds assigned to both
pads. You can stack as many sounds as there are drum pads, but you'll most often need to
have enough drum groups to create a drum set. Typically, the snare would be stacked with
one or two other sounds and the kick might be stacked with one other sound. Of course, the
actual use is totally up to you, but the possibilities are endless.

The operation is a simple copy function performed when the IDM01 is in stop mode and can be
done at any time: while developing a rhythm pattern, during mixdown, if you're driving the
IDM01 live through MIDI, or stack sounds on the IDM01's preset rhythm patterns. In
conjunction with the IDM01's mix, pan, and tune functions, you can customize the drum sound
to the specific needs of the song you are working on. This kind of flexibility makes the IDM01 a
powerful production tool in the critical decision making process that gives personality to
recorded music.

8.3B Sound Stacking when Using the IDM01 as a Drum Machine

When used as a drum machine, one pad's rhythm can be copied to another pad so that as the
Pattern plays, both pads double a part (use the directions in section 3.3B to perform Sound
Stacking). You can also copy the rhythm to additional pads if desired.

8.3C Editing Stacked Combinations

Remember that the stacked sounds can be further modified with the Drum Set parameters.
Example: Timbale could be stacked with a snare, but mixed a bit lower than the snare to give
the snare sound a "ring" without overpowering it.

Tuning changes can also be very effective. Example: Slightly detune two identical drums to
create a thicker sound.

8.3D Sound Stacking via MIDI

When using the IDM01 as an expander module, each pad responds to a particular MIDI note
number. Assigning two pads to the same note number (section 6.4) stacks those two pads into
one combined sound (as triggered by the assigned MIDI note number). You are not limited to
assigning two pads to the same note number—trigger all the pads from one MIDI note if you
dare.

59

8.4 UNDERSTANDING RHYTHMIC NOTATION

Measures A piece of music is divided into smaller units called measures (also called bars), and each

measure is divided into beats. In the IDM01, each beat is further sub-divided into 96 sub-beats.
Rhythmic Values for Notes With a measure written in a 4/4 time signature, there are 4 beats per

measure, and each beat represents a quarter (1/4) note. Thus, there are 4 quarter notes per measure
of 4/4 music. With a 3/4 time signature the "numerator" indicates that there are 3 beats per measure,
while the "denominator" indicates that each of these beats is a quarter note (1/4).

There are two eighth notes per quarter note. Thus, there are eight eighth notes per measure of 4/4
music.

There are four16th notes per quarter note. Thus, there are sixteen 16th notes per measure of 4/4
music.

There are eight 32nd notes per quarter note. Thus, there are thirty-two 32nd notes per measure of 4/4
music.

There are also notes that span a greater number of beats than quarter notes. A half note equals two
quarter notes. Therefore, there are two half notes per measure of 4/4 music. A whole note equals four
quarter notes, so there is one whole note per measure of 4/4 music. (We keep referring these notes to
4/4 music because that is the most commonly used time signature in contemporary Western music.)

Triplets The above notes divide measures by factors of two. However, there are some cases where
you want to divide a beat into thirds, giving three notes per beat. Dividing a quarter note by three
results in eighth-note triplets. The reason why we use the term eighth-note triplets is because the
eighth note is closest to the actual rhythmic value. Dividing an eighth note by three results in 16th-note
triplets. Dividing a 16th note by three results in 32nd note triplets.

Rests You can also specify where notes should not be played; this is indicated by a rest, which can
be the same length as any of the rhythmic values used for notes.

Dotted Notes and Rests Adding a dot next to a note or rest means that it should play one-and-one­half times as long as the indicated value. This of course does not apply to percussion parts. Example: A
dotted eighth note would last as long as three 16th notes (since an eighth note is the same as two 16th
notes).

Uncommon Time Signatures 4/4 (and to a lesser extent 3/4) are the most common time signatures in
our culture, but they are by no means the only ones. In jazz, both 5/4 (where each measure consists of
five quarter notes) and 7/4 (where each measure consists of seven quarter notes) are often used. In
practice, complex time signatures are played like a combination of simpler time signatures; for example,
some 7/4 compositions would have you count each measure not as 1, 2, 3, 4, 5, 6, 7 but as 1, 2, 3, 4,
1, 2, 3. It's often easier to think of 7/4 as one bar of 4/4 followed by one bar of 3/4 (or the other way
around, depending on the phrasing), since as we mentioned, 4/4 and 3/4 are extremely common time
signatures.
