GM System Level 1
“GM System Level 1” is a standard specification that
defines the arrangement of voices in a tone generator
and its MIDI functionality, ensuring that data can be
played back with substantially the same sounds on any
GM-compatible tone generator, regardless of its manufacturer or model.
Tone generators and song data that meet the “GM
System Level 1” bear this GM logo.
XG
“XG” is a tone generator format that expands the voice
arrangement of the “GM System Level 1” specification
to meet the ever-increasing demands of today’s computer peripheral environment, providing richer expressive power while maintaining upward compatibility of
data. “XG” greatly expands “GM System Level 1” by
defining the ways in which voices are expanded or
edited and the structure and type of effects.
When commercially available song data bearing the XG
logo is played back on a tone generator which bears the
XG logo, you will enjoy a full musical experience that
includes unlimited expansion voices and effect functions.

The MU15 — What It Is and What It Can Do
The MU15 — What It Is and
What It Can Do
What It Is...
The MU15 is a compact, highly portable and easy-to-use tone
generator. It features XG compatibility with a stunning variety of 480
XG Voices (including 128 GM Voices) and 11 Drum Voices (with
Drum and SFX kits).* The MU15 has 32-Voice polyphony and is 16Part multi-timbral. In other words, the MU15 has 16 different Parts,
each with its own Voice, so that up to 16 different Voices can be
sounded simultaneously.
With the built-in two-octave keyboard, you can play any of the Voices
directly from the MU15 itself. Or you can play them from a connected MIDI keyboard. In addition, the MU15 also has a TO HOST
terminal for easy interfacing with a computer, allowing you to play
the Voices using your favorite music software. This is where the
advanced multi-timbral capabilities come in, letting you play up to 16
different Voices at the same time.
10
* The MU15 has a total of 676 different Voices. A separate
TG300B mode (page 43) features 579 Voices, some of which are
diiferent than the XG set.
What It Can Do...
Here are a few ideas on how you can use the MU15. The list below
is not comprehensive, but is meant to be a general guide to the
possibilities and provide a starting point or springboard for your own
creative ideas and explorations.
Carry It With You
If you have a laptop computer (and sequencing software), simply
connect the MU15, plug in some headphones and you’ve got a
complete music making system that’s ready to go wherever you go.
Page 11
The MU15 — What It Is and What It Can Do
Use it for composing, arranging, practicing or making/playing demos
for your band.
Perform With It
Bring it with you to a gig — as long as there’s a MIDI keyboard on
stage, you can use the high-quality sounds of MU15 in your performance.
Multimedia
Since it’s portable and compatible with General MIDI, the MU15 is a
natural for multimedia applications. Bring it with you to a presentation — since the computer interface is built-in to the MU15, it hooks
up instantly and easily to the computer’s serial port without the need
for any other equipment.
Using With MIDI Keyboard
Use the MU15 as supplementary tone generator with your MIDI
keyboard and play the Voices of both instruments in a layer together.
Or, if your keyboard has the capability, program a “split” so that the
notes you play on the right side of the keyboard play only the Voices
of the MU15.
English
Using With Other MIDI Controllers
Even if you’re not a keyboard player, you can still play the MU15 with
other types of MIDI controllers. For example, use a MIDI percussion
controller to play the drum and percussion sounds of the MU15.
Guitar controllers (such as the Yamaha G50) or wind controllers (such
as the Yamaha WX5) are also available for players of those instruments.
Home Studio Setup
The MU15 integrates easily into any existing setup. If you have a
MIDI keyboard, computer and sequencing software, the MU15 with
its high-quality Voices and multi-timbral capabilities can expand your
home studio system.

Page 12
The MU15 — What It Is and What It Can Do
About General MIDI (GM)
General MIDI (GM) is a new addition to the worldwide MIDI standard. MIDI, as you know, stands for Musical Instrument Digital
Interface, and makes it possible for various electronic musical
instruments and other devices to “communicate” with each other.
For example, by connecting a sequencer to the MU15’s MIDI IN
terminal, you could play back a song on the sequencer using the
Voices of the MU15.
So, where does GM fit in all of this? One of the most important
features of General MIDI is in the standardization of Voices. This
means that a song recorded in the GM standard can be played back
on any GM-compatible tone generator and sound just as the composer intended. For example, if there is an alto sax solo in the song,
it will be played by an alto sax Voice on the General MIDI tone
generator (and not by a tuba or harpsichord!). Since the MU15 is
fully GM-compatible, you can take advantage of the vast wealth of
musical material recorded in that format.
About XG
The Yamaha XG format is an extension of General MIDI, and provides a number of significant improvements and enhancements. XGcompatible song data takes advantage of the expanded Voice set,
extensive MIDI control and built-in effects of the MU15 (as well as
other MU-series instruments).
12
To get the most out of XG and your MU15, we recommend using
XG-compatible instruments and software. For example, the Yamaha
CBX-K2 keyboard lets you dynamically control a variety of parameters in real time while you play. The XGworks sequencer software
not only lets you playback GM- or XG-compatible song data, it lets
you record your own songs — and gives you enormously powerful
and easy-to-use editing tools for adjusting detailed settings of the
MU15 that are unavailable with the panel controls.

Guided Tour
Guided Tour
When using your MU15 for the first time, read
through this short section of the manual. It guides you
step-by-step in using many of the basic operations: setting
the instrument up, connecting it properly to other equipment, and — most importantly — playing it. It also introduces you to most of the other, advanced features and
operations of the instrument — enabling you to quickly
and effectively get the most out of your new MU15.
Setting Up Your MU15
Since the MU15 has a built-in keyboard, you could use it with nothing more
than a set of batteries and a proper set of stereo headphones. It can also be
used effectively with a computer in a “desktop music” system.
English
In this section, however, you’ll learn how to connect the MU15 in a basic
system with a MIDI keyboard and an external amplifier/speaker system. (For
basic information on MIDI and its applications, see page 91.)
What You’ll Need
• The MU15 and a proper power supply (either an AC adaptor or
batteries).
• A MIDI keyboard, electronic piano, or any instrument that can
output MIDI data.
• An amplifier speaker system, preferably stereo. Alternately, you
can use a set of stereo headphones.
• Audio connecting cables.
• A MIDI cable.
17
Page 18
Setting Up Your MU15
Power Supply
Although the MU15 will run either from an optional AC adaptor or batteries,
Yamaha recommends use of an AC adaptor whenever possible. Moreover, an
AC adaptor is more environmentally friendly than batteries and does not
deplete resources.
CAUTION
• Before making any connections, make sure that all equipment to be connected is
turned off.
Using a Power Adaptor
Connect one end of the power adaptor (Yamaha PA-3B) to the DC IN
jack on the rear panel, and the other end to a suitable electrical
outlet.
18
WARNING
• Do not attempt to use an AC adaptor other than the PA-3B. The use of
an incompatible adaptor may result in irreparable damage to the MU15,
and even pose a serious shock hazard.
CAUTION
• When connecting the AC power adaptor, first make sure that the MU15
is turned off (set to STANDBY). Next, connect one end of the power
adaptor to the DC IN jack on the MU15, and connect the other end to
an appropriate AC outlet.
• The MU15 has a convenient data backup feature that maintains any
changes you’ve made to the settings, even when the power is turned
off. However, removing the batteries or disconnecting the AC adaptor
automatically clears the data and restores the factory defaults. To save
your important data, use the Dump Out function (page 65).
Page 19
Setting Up Your MU15
Using Batteries
To use the MU15 on battery power, insert six 1.5V AA size (SUM-3,
R-6 or equivalent) manganese or alkaline batteries in the battery
compartment. Make sure to follow the polarity indications on the
bottom case (and as shown below).
Securely replace the battery compartment cover when done installing the batteries.
When to Replace the Batteries
When the battery power runs too low to operate the MU15, the
sound may become distorted and the following display will appear:
English
Battery
When this happens, replace all batteries with a complete set of six
new batteries of the same type.
CAUTION
• NEVER mix old and new batteries or different types of batteries! Also,
to prevent possible damage due to battery leakage, remove the
batteries from the instrument if it is not to be used for an extended
period of time.

Selecting Voices
The MU15 has a total of 676 different instrument Voices. Here, we’ll select a
different Voice for playing.
Each Voice is numbered, and there are 128 Voices from which you can immediately select. (We’ll see how to select Voices outside of these 128 later.)
Operation
Use the VALUE buttons.
Pressing the VALUE /YES button steps up through Voice numbers
while pressing the VALUE

down) the other. For example, to rapidly decrease the value, simultaneously hold down the
/NO button and press the /YES button.
About Parts, Voices, and Banks
Before we go on to the next section, a little explanation about the organization
of the MU15 is needed. Here, you’ll learn about Parts, Voices, and Banks —
three important concepts around which the sounds of the MU15 are organized.
24
Page 25
Playing the MU15
Voices
As mentioned in the section “The MU15 — What It Is and What It
Can Do,” the MU15 is capable of playing sixteen different instrument sounds at the same time. Each instrument sound is called a
“Voice,” and the MU15 has 676 different Normal Voices, as well as
21 Drum Voices.
Let’s say, for example, you have a song in which you want to use the
following sixteen Voices:
Grand Piano Pick Bass Steel Guitar Rock Organ
Tenor Sax Alto Sax Trumpet Flute
Marimba Drums Violin Cello
Strings Warm Pad Sweep Pad Saw Lead
Parts
For these Voices to be used simultaneously, they must be assigned
to different “Parts.” These correspond exactly to the parts of a song
or the elements of a band, such as bass, guitar, and drums.
English
Part 1 Part 2 Part 3 Part 4
Grand Piano Pick Bass Steel Guitar Rock Organ
Part 5 Part 6 Part 7 Part 8
Tenor Sax Alto Sax Trumpet Flute
Part 9 Part 10 Part 11 Part 12
Marimba Drums Violin Cello
Part 13 Part 14 Part 15 Part 16
Strings Warm Pad Sweep Pad Saw Lead
Obviously, each Part can have its own Voice setting, but it can also
have independent settings for other aspects of the sound as well, as
we’ll see later.
NOTE
• Part 10 is normally reserved for Drum Voices, although this can be
changed. (Page 28.)
25
Page 26
Playing the MU15
Banks
As you learned in “Selecting Voices” above, each Voice is numbered,
and there are 128 of them from which you can select. These 128
Voices make up a Voice “Bank.” The MU15 has many Banks, each
of which contain 128 Voices. By selecting a different Bank, you can
select different Voices — any of the 676 Voices available on the
MU15.
Now, let’s go on to the next sections and see how to select different
Parts, and how to select Voices on the other Banks.
Selecting Parts
In “Selecting Voices” above, you learned how to select a Voice. Here, you’ll
see how to select a different Part and select a different Voice for that Part.

Selecting Banks
As you learned in “About Parts, Voices, and Banks” above, the MU15’s 676
Voices are organized into Banks of 128 Voices each. Here, we’ll see how to
select Voices of different Banks.
Operation
Z Select the desired Part.
Do this in the normal way, by using the PART buttons.
X Select the desired Voice.
Do this in the normal way, by using the VALUE buttons.
In general, the Voice Banks feature variations on the basic Voices —
for example, the “PercOrgn” Voice has several similar sounding
organ Voices at the same Voice number, but in different Banks.
That’s why it’s a good idea to decide which type of Voice you want,
and then call up different Banks to select a specific Voice variation.

Holding down the XG BANK button and pressing the VALUE /YES
button steps up through Bank numbers while doing the same with
the VALUE
Notice that the Bank numbers jump to seemingly random values.
For example, if you’ve selected Voice number 005 “E.Piano1,”
holding down the XG BANK button and pressing the VALUE
button will step through the following Banks:
/NO button steps down through the numbers.

…and so on.
In this way, the MU15 skips over Banks that have the same Voices
as the basic Bank (Bank 000), and lets you automatically jump to
Banks that have unique Voices for the selected Voice number. In the
above example, Banks 002 - 017 all have the same Voice for number
005: “E.Piano1.” Bank 018 has a unique Voice, followed by another
unique Voice at Bank 032, and so on.
NOTE
• When the SFX kit (XG Bank #126) or Drum kit (XG Bank #127) is
selected , the Voice number is automatically set to 001.
Playing Drum Voices
The MU15 also features a wide selection of dynamic, realistic drum and
percussion sounds. These sounds are grouped together in Drum Voices and
each note on the keyboard plays a different drum or percussion sound.
NOTE
• For details on which drum sounds are assigned to which notes of the keyboard,
refer to the Drum Map charts on pages 80 - 83.
28
Operation
Z Select Part 10.
Do this in the normal way, by using the PART buttons.
NOTE
• Part 10 is assigned to a Drum Voice by default. However, any Part can
be set to a Drum Voice by selecting Bank 126 or 127 for the Part.

Playing the MU15
X Select the desired Drum Voice.
Do this in the normal way, by using the VALUE buttons.
C Play the drum sounds.
Play the sounds from the MU15’s keyboard or from a connected
MIDI keyboard.
Since the various drum/percussion sounds are spread out over
several octaves, in order to play them from the MU15, you’ll need to
change the octave setting (see next section).
Changing the Octave Setting
Although the MU15’s built-in keyboard has a two-octave range, you can
actually play it over a range of ten octaves.
Operation
Use the OCT DOWN / OCT UP buttons.
Pressing the OCT DOWN button lowers the pitch by one octave, and
pressing the OCT UP button raises it by one octave. The current
octave setting is shown in the display. (No indication appears when
the octave setting is normal.)
English

the pitch is two octaves above normal.)
NOTE
• For Normal Voices (such as Piano or Strings), this changes the pitch.
For Drum Voices, this changes the drum/percussion sounds playable
from the keyboard.
You can instantly restore the normal octave setting by pressing both
OCT DOWN / OCT UP buttons simultaneously.

Page 30
Playing the MU15
Editing a Part
The editing features of the MU15 provide various controls for changing the
Parts and setting other important operating functions. Among other things,
these let you set the Volume or Pan setting of each Part independently, change
the Velocity of the built-in keyboard, and save your edits to a connected
computer, sequencer or data storage device.
NOTE
• The Velocity and Local Control settings cannot be saved.
Editing on the MU15 is basically divided into three types of controls: Part,
Effect, and Utility. In this section, you’ll learn how to change the Note Shift
setting and the Volume setting (both Part controls). However, the instructions
given here are fundamentally the same for all editing operations. (See the
Reference section of this manual for information about the specific editing
functions.)
Changing the Note Shift and Volume Settings
The Note Shift parameter lets you change the key (pitch) of the
selected Part. This only affects the Normal Voices, and does not
change the pitch of the Drum Voices.
30
The Volume parameter allows you to change the level of each Part’s
Voice, letting you set a custom balance or mix of all the Parts.
Operation
Z Select the desired parameter.
For Note Shift, simultaneously hold down the PLAY/EDIT button and
press the NOTE SHFT button. Doing this enters the Edit mode and
calls up the Note Shift parameter.

To select Volume, hold down PLAY/EDIT and press the VOL button.
X Change the value.
Use the VALUE buttons. For Note Shift,
the value changes in semitone steps up or
down, depending on which VALUE button
you press. For Volume, the value can be
changed over a range of 0 (minimum) to
127 (maximum).
Play the MU15 keyboard (or the connected MIDI keyboard) and hear
the change in the sound of the Part.
You can continue to change the selected setting with the VALUE
buttons and play the keyboard to hear the results of the changes. If
you wish, you can also easily change the setting for different Parts
by using the PART buttons to select the desired Part. To switch
between the desired parameters, repeat step #1 above.
English
C To return to the Play mode, press the PLAY/EDIT button
again.
Soloing and Muting Parts
The MU15 has convenient Solo and Mute functions for selectively soloing or
muting any of the sixteen Parts. These functions are especially useful when
playing back song data from a connected computer or sequencer, since they
let you isolate specific Parts in the mix and hear how they sound by themselves or how the rest of the song sounds without them.
For instructions on using Solo and Mute, see pages 48 and 49.
31
Page 32
Playing the MU15
Using the Effects
The compact MU15 is packed with an enormous amount of sonic power and
flexibility. In addition to the huge amount of instrument Voices, the MU15
features a built-in multi-effect processor with three independent digital effects:
Reverb, Chorus, and Variation.
In this section, you’ll learn how to apply the effects, change the effect type,
and set how much effect is applied for each Part. (See the Reference section
of this manual for information about specific effect parameters.)
Using Reverb and Chorus
Judicious use of Reverb creates a sense of space and enhances the
realism of the Voices. The Reverb Type that you select is applied to
all Parts; however, the amount of Reverb for each Part can be
adjusted. This lets you add special textures to the mix of a song,
such as “drenching” one Part in Reverb while another Part is kept
“dry.”
The Chorus effect section features a variety of pitch modulation
effects. These let you subtly enhance or “fatten” the sound, or
completely transform the sound in wild and unique ways. As with
Reverb, only one Chorus Type can be used for all Parts; however, the
amount of Chorus for each Part can be adjusted.
32
Since the methods of using Reverb and Chorus are identical, both
are covered here together.
Operation
Z Select the desired Part.
Do this in the normal way, by using the PART buttons.
X Set the Send Level controls to appropriate values.
Before you actually change the Reverb or Chorus settings, you
should set the Send Level controls, in order to properly hear the
effect and the changes you make.
Page 33
Playing the MU15
To do this, simultaneously hold down the PLAY/EDIT button and
press the REVERB SEND LVL button (for Reverb), or the CHORUS
SEND LVL button (for Chorus), and then set the value to “60” or
higher, by using the VALUE buttons.
RevSend
C Select the Reverb Type (or Chorus Type) parameter.
Simultaneously hold down the PLAY/EDIT button and press the
REVERB TYPE button (for Reverb), or the CHORUS TYPE button (for
Chorus).
Hall1
V Select the desired Reverb (or Chorus) Type.
Use the VALUE buttons. For a list of the available Reverb Types, see
page 57. For a list of the available Chorus Types, see page 58.
English
B Set the Send Level control to the desired value.
Once you’ve selected an Reverb or Chorus Type to your satisfaction,
you can re-adjust the effect level for the selected Part (and other
Parts, too). To do this, repeat steps #1 and #2 above.
Using the Variation Effects
The Variation effect section provides a wealth of additional effects,
with which you can enhance or radically change the sound of the
Voices.
Variation can be applied to all Parts (just as with Reverb and Chorus),
or to a single selected Part. (For more information on the Variation
effect, see page 59.)

re-adjust the effect level for the selected Part (and other Parts, too).
To do this, repeat steps #1 and #3 above.
M Set the Dry Level control to the desired value.
This parameter gives you additional fine control over the Variation
effect balance. Setting this to a low value turns down the level of
the “dry” sound and emphasizes the Variation effect sound.
To do this, simultaneously hold down the PLAY/EDIT button and
press the DRY LVL button, and then set the value by using the
VALUE buttons.

Using the MU15 with a Computer/Sequencer
Using the MU15
with a Computer/Sequencer
By connecting the MU15 to a computer or sequencer, you have a powerful
music system for playing back songs and even creating your own songs, using
the Voices of the MU15.
First, you’ll have to make sure that the MU15 is properly connected to the
computer or sequencer, and that your music software is ready to run. (Refer to
page 37 for connection examples and instructions.) If you are using the TO
HOST terminal or if both MIDI terminals are properly connected, you should be
able to play songs from your software and enter notes to the software from
the MU15.
Using the MU15 with a MIDI Data Storage Device
You can also use the MU15 with a MIDI data storage device, such as
the Yamaha MDF3 MIDI Data Filer. This lets you save or back up
changes you’ve made in the settings of the Edit mode. Then, when
you want to recall those settings, you can transfer the appropriate
data from the storage device.
The MDF3 also allows you to play compatible song data on the
MU15 directly from the MDF3 itself, without the need of a sequencer.
Make sure that the MU15 is properly connected to the data storage
device (via MIDI). (Refer to page 66 for the connection example.)
Use the Dump Out function (page 65) to send data to the device.
Also refer to the owner’s manual of your data storage device for
specific operating instructions in receiving or sending data.
Setting Up
The MU15 features a built-in host computer interface, allowing you to directly
connect it to your computer — eliminating the need for installing a special
MIDI interface to your computer. This also makes it easier to use the MU15

If your computer already has a MIDI interface, you can connect the MU15 to it
by using MIDI cables instead.
Depending on the computer or interface used, you should set the HOST
SELECT switch to the appropriate setting: MIDI, PC-1, PC-2, or Mac. For
information on proper cables, see the section “MIDI/Computer Connecting

Page 40
Using the MU15 with a Computer/Sequencer
Playing Song Data
Once you set up your computer or sequencer with the MU15, you’re ready to
play back song data using the Voices of the MU15. Although any GM-compatible song data can be played, the MU15 will sound best when used with XGcompatible song data.
By using Yamaha’s XGworks Music Sequencer software, you can create your
own XG song data. Since XGworks also features a special XG Editor, you can
conveniently and easily edit any of the “hidden” parameters of the MU15.
This gives you comprehensive control over the Voices and effects. (For more
information on the “hidden” parameters, see the “MIDI Data Format” section,
page 91.)
When you do any editing to the MU15 for your own songs, you should save
your settings (as System Exclusive data) to the computer with the Dump Out
function (page 65). It’s especially useful to record this data at the beginning of
a song, so that the MU15 will be set properly for the particular song. Make
sure to enter several measures of silence before the song starts to accommodate the System Exclusive data.

Play Mode
Play Mode
The Play mode is the default mode of the MU15 and is automatically set when
the power is turned on. The Play mode allows you to play the Voices, either
from the MU15’s keyboard or from a MIDI device. Depending on data received
via MIDI, the MU15 operates in one of two Sound Module modes: XG or
TG300B. (XG is the default.)
The Play mode also lets you select Voices, Banks, and Parts, and change the
octave setting of the keyboard. If the Edit mode is selected, you can return to
the Play mode by pressing the PLAY/EDIT button.
For general instructions and details on various Play mode operations, refer to
the Guided Tour section.
Sound Module Mode
The MU15 plays Voices in one of two Sound Module modes: XG or TG300B.
The Sound Module mode is one of the “hidden” parameters of the MU15 and
can be changed only by incoming MIDI data. Normally this data is recorded at
the start of commercially available sequenced songs. If the song data is XGcompatible, the XG mode will be selected, letting you take advantage of the
MU15’s full performance power. If the song data is GM-compatible but
intended for another manufacturer’s tone generator, the TG300B mode will be
selected, enabling optimum playback of the song data.
English
You can change this setting yourself by the use of MIDI System Exclusive
messages (page 91), either as part of sequenced song data, or received from a
device that allows you to send user-specified System Exclusive data.
NOTE
• The last selected Sound Module mode is automatically enabled when the power is
turned on. However, if both the batteries and AC adaptor are removed (or if the
PLAY/EDIT button is pressed), the XG mode is automatically enabled.
When the TG300B mode is selected, the following display appears:
*
*
43
Page 44
Edit Mode
The XG mode features 480 Normal Voices (including 42 SFX Voices) and 11
Drum Voices (including 2 SFX drum kits). The TG300B mode features 579
Normal Voices and 10 Drum Voices.
NOTE
• In the TG300B mode, the Voices can only be selected by MIDI; they cannot be
selected from the panel of the MU15.
Edit Mode
The Edit mode allows you to change various settings and parameters of the
MU15. These controls are divided into three basic types: Part (page 45), Effect
(page 56), and Utility (page 63).
The basic method of editing is fundamentally the same for all of the parameters. Many of the parameters can be set independently for each Part, and as
such allow you to select the Part to be edited.
NOTE
• Keep in mind that the settings you make may automatically change when playing
back song data on a connected sequencer. If you want to save your original
settings, use the Dump Out function (page 65) before playing the song.

The Part controls allow you to change certain parameters for each
Part. These include Volume, Pan, Note Shift, Filter, EG (Envelope
Generator) and Vibrato. All of these parameters can be set independently for each Part, giving you enormous and flexible control over
the sound. Also included in the Part controls are the convenient Solo
and Mute functions. The Effect Send Level parameters (pages 57,
59, 61) can also be adjusted for each Part.

NOTE
• Keep in mind that when playing the MU15’s keyboard, the actual sound
level of a selected Part also depends on the Velocity parameter in the
Utility controls (page 64). If the Velocity setting is at or near the
minimum, the Part may be very low in level, no matter what the
Volume setting made here.

Solo
Part
While a song is playing back on your computer or sequencer, you can
selectively solo any of the 16 Parts of the MU15. Solo lets you
isolate a single Part, to hear how that Part sounds by itself.
Along with Mute (page 49), Solo is an effective tool that helps you as
you edit the Parts, since it allows you to better hear how the
changes you make affect specific Voices as well as the overall
sound.

Filter Parameters — Cutoff Frequency
and Resonance
The MU15 features digital filters for each Part that allow you to change the
timbre or tone of the Voices. The filters are affected (together with the level)
by the EG (Envelope Generator) parameters, which allow you to change the
timbre over time as well. (Page 52.)
Cutoff Frequency

setting
Selected
Cutoff
Part
Range: -64 - +63
Default: 0
This determines the cutoff frequency of the filter. The filter effectively takes out frequencies higher than the cutoff point and
“passes” the lower frequencies. Lower cutoff values create a
deeper, more rounded tone, while higher values create a brighter
tone.

EG (Envelope Generator) Parameters —
Attack Time and Release Time
The EG parameters allow you to shape the sound of a Part’s Voice — or, in
other words, set how the level and timbre of the Voice changes over time.
The relationship of the two EG parameters — Attack Time and Release Time —
are shown in the illustrations below. These parameters affect both the volume
of the Voice and its timbre (with the Filter parameters; page 50).

Part
Shows Attack Time
setting for each
Part.
Range: -64 - +63
Default: 0
This determines the Attack Time of the EG, or how long it takes for
the sound to reach full volume when a note is played. Higher
positive values result in a longer, slower attack. For the Filter, this
determines how long it takes for the sound to be affected by the
Filter values.
Release Time
Release Time
setting
Selected
RelsTime
Part
Shows Release
Time setting for
each Part.
English
Range: -64 - +63
Default: 0
This determines the Release Time of the EG, or how long the sound
sustains after a note is released. Higher positive values result in a
longer, slower sustain. For the Filter, this determines how long the
Filter effect continues after a note is released.
NOTE
• Short percussive Voices (such as Marimba) whose sound decays very
quickly may not be affected by the Release Time parameter, depending
on how long the key is held. For example, if the key is held until the
sound completely dies out, there will be no sound to slowly sustain, no
matter what the Release Time setting is.

Vibrato Parameters — Rate, Depth, and Delay
Vibrato produces a quavering, vibrating sound in the Part’s Voice, by regularly
modulating the pitch. You can control the speed and depth of the Vibrato, as
well as the time it takes before the Vibrato effect is applied.
Vibrato Rate
Vibrato Rate
setting

VibRate
Part
Range: -64 - +63
Default: 0
This determines the speed of the Vibrato effect. Negative values
produce a very slow Vibrato, while higher values result in a faster
Vibrato sound.

VibDelay
Part
Range: -64 - +63
Default: 0
This determines the delay in the start of the Vibrato effect. Delay is
effective especially for producing a natural sound on stringed
instrument Voices. For example, violin players often use delayed
Vibrato, especially while playing long notes. The Delay parameter is
useful in recreating this effect, producing a richer, more lifelike
sound. Higher values result in a longer Delay time.
