This symbol indicates
explanations about
dangerous matters. If users
ignore this symbol and handle
the device the wrong way,
bodily injury and damage to
the equipment could result.

Please observe the following safety tips and
precautions to ensure hazard-free use of the
MRT-3.

About power

Since power consumption of this unit is
fairly high, we recommend the use of an AC
adapter whenever possible. When powering
the unit from the batteries, use only an
alkaline type.

AC adapter operation

• Be sure to use only an AC adapter which
supplies 9 V DC, 300 mA and is
equipped with a "center minus" plug
(Zoom AD-0006).

The use of an adapter other than the
specified type may damage the unit and
pose a safety hazard.

• Connect the AC adapter only to an AC
outlet that supplies the rated voltage
required by the adapter.

• When disconnecting the AC adapter from
the AC outlet, always grasp the adapter
itself and do not pull at the cable.

• If the unit is not to be used for a long
time, disconnect the AC adapter from the
outlet.

Battery operation

• Use four IEC R6 (size AA) batteries
(alkaline or manganese).

• The MRT-3 cannot be used for
recharging.

Pay close attention to the labelling of the
battery to make sure you choose the
correct type.

• If the MRT-3 is not to be used for an
extended period of time, remove the
battery from the unit.

• If batteries leakage has occurred, wipe
the battery compartment and the battery
terminals carefully to remove all
remnants of battery fluid.

• While using the unit, the battery
compartment cover should be closed.

Environment

Avoid using your MRT-3 in environments
where it will be exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

Handling

• Since the MRT-3 is a precision electronic
device, avoid applying excessive force to
the controls. Do not operate the keys or
controls with your foot.

•Take care that no foreign objects (coins
or pins etc.) or liquids can enter the unit.

• Be sure to turn the power to all
equipment off before making
connections.

• Before moving the unit, turn the power
off, and disconnect all cables and the AC
adapter.

Alterations

Never open the case of the MRT-3 or
attempt to modify the product in any way
since this can result in damage to the unit.

In Case of Trouble

If there seems to be a defect or a problem
with the unit, immediately disconnect the
AC adapter or remove the batteries to shut
off the power. Then disconnect any other
cables connected to the unit.

Usage Precautions

• Electrical interference

For safety considerations, the MRT-3 has
been designed to provide maximum
protection against the emission of
electromagnetic radiation from inside the
device, and protection from external
interference. However, equipment that is
very susceptible to interference or that emits
powerful electromagnetic waves should not
be placed near the MRT-3, as the possibility
of interference cannot be ruled out entirely.

With any type of digital control device, the
MRT-3 included, electromagnetic
interference can cause malfunctioning and
can corrupt or destroy data. Care should be
taken to minimize the risk of damage.

• Cleaning

Use a soft, dry cloth to clean the MRT-3. If
necessary, slightly moisten the cloth. Do not
use abrasive cleanser, wax, or solvents (such
as paint thinner or cleaning alcohol), since
these may dull the finish or damage the
surface.

Please keep this manual at hand for
future reference.

Thank you for purchasing the ZOOM Micro RhythmTrak MRT-3 (subsequently referred to as
"

the MRT-3").

The MRT-3 offers the following attractive features.

●

Sophisticated rhythm machine incorporates 199 super-realistic drum and
percussion sounds in an amazingly compact body. A full 396 preset patterns
contain a wide variety of preprogrammed rhythms. 99 additional patterns can
be programmed and stored by the user.

●

Create a backing sequence (song) with up to 99 patterns. As many as 99 such
songs can be stored for immediate use at any time.

●

Internally lit pads let you follow the rhythm pattern visually during song
playback or when using a pattern.

●

Choose up to 14 sounds from the built-in drum and percussion sources, and
then adjust level, tuning, and panning individually to create your very own
drum kit. This gives you the flexibility to realize your creative vision.

●

Perfectly intuitive and simple design lets you master the unit right away, even
if you have never used a drum machine before.

●

Optional foot switch FS01 allows pattern start/stop control or tempo switching.
You can also operate an assigned sound such as bass drum or open/closed hi­hat.

●

MIDI IN connector allows use with an external MIDI sequencer or other
device. The Multitrak Recording Studio ZOOM MRS-4 is an ideal match,
letting you synchronize the audio tracks from the recorder with the rhythm
track from the MRT-3. Playing the sounds of the MRT-3 with an external MIDI
component is also possible.

Please take the time to read this manual carefully so as to get the most out of your
MRT-3 and to ensure optimum performance and reliability.

Pattern

Playing a rhythm using sounds stored in the MRT-3 is called playing a pattern. The information
stored in a pattern includes data such as pattern length, beat, and which kit (combination of
drum/percussion sounds) is used.
The patterns are organized in banks (A – D, U) and numbers (01 – 99). The MRT-3 has 396
read-only preset patterns (A01 – D99) and 99 read/write user patterns (U01 – U99).

■

Song

A song is a sequence of patterns played in subsequent steps. The maximum number of steps in
a song is 99. Provided that there is free memory, the MRT-3 has the capability to store up to 99
songs.
A song includes data such as pattern number, overall song tempo (master tempo), tempo
change information, volume change information, dedicated kit information, etc.

Kit

The MRT-3 lets you select 14 sounds from the built-in drum and percussion sources to use for
playing with the pads. A combination of such sounds, together with pad sensitivity information
and level/tuning information for each pad is called a kit. The MRT-3 has a capacity for 70 kits.
Kits 01 – 50 are read-only preset kits and kits 51 – 70 are read/write user kits.

■

Pad/Pad Bank

Each pad on the MRT-3 can be used to play the currently selected sound, and to record it as a
phrase in a pattern.
To be able to play 14 sounds with the 7 pads on the unit, pads are grouped in two banks (A and
B) which can be switched with the [PAD BANK] key. When the [PAD BANK] key is out, bank
A is selected. When the key is lit, bank B is selected.

To specify the tempo manually, tap the [TEMPO] key twice or more in the desired
tempo (tap input function).

If you tap the [TEMPO] key twice or more often while a pattern is playing or stopped, the
tapping interval of the last two taps is taken as the quarter note tempo. This allows you to
simply set the tempo in sync with a song.

The tempo set in pattern mode applies to all patterns. It is not possible to set the tempo for a
pattern individually.

Real-Time Pattern Recording

The MRT-3 has 99 user pattern slots which can be filled with your own patterns. Creating and
recording a pattern is possible in two ways: by actually playing the pattern on the pads (real-time
recording), or by entering each sound individually (step recording).
This section describes the procedure for real-time recording.

1.

In pattern mode, select an empty user pattern (U01 – U99). If necessary, select a kit.

When you select an empty user pattern, the indication "E" appears on the right side of the
display.

• If you change the kit in pattern mode while a user pattern is selected, the last selected kit will be

stored for that pattern.

•You can also erase a recorded user pattern to return it to the empty state. See page 24.

2.

Press the [FUNCTION] key and then pad 3 (QUANTIZE).

The display shows the current quantize setting. Quantization refers to the degree of detail
with which notes are recorded. By setting the quantize value to the shortest note that you

HINT

ZOOM MRT-3

16

Using Patterns (Pattern Mode)

Ta p twice

NOTE

@ 01E

want to use for the pattern, recording can be carried out while automatically maintaining
precise timing.

3.

Use the [VALUE +/-] keys to set the quantize value (shortest note to be recorded).

The following settings are available.

The selected setting will be used as shortest note for real-time recording.

4.

Press the [FUNCTION] key again.

• The quantize setting applies to all patterns. When recording another pattern with the same
resolution, it is not necessary to set the quantize value again.

• By changing the quantize setting after recording is completed, you can add another part with
different resolution to the same pattern. For example, after recording bass drum and snare drum
using sixteenth notes, you may want to record a hi-hat sequence with thirty-second notes.

• If desired, you can change the resolution of a recorded phrase afterwards. For details, see the
section "Changing User Pattern Resolution After Recording".

5.

While holding down the [REC] key, press the [PLAY] key.

The [REC] key and [PLAY] key light up. The [TEMPO] key flashes in sync with the tempo,
and one measure of precount clicks is heard before recording starts. During recording,
metronome clicks are heard, and the display shows the current position in the pattern
(measure/beat).

• Unless specified otherwise, the beat and duration of an empty pattern where nothing has been
recorded are the same as those of the most recently selected recorded pattern. If desired, you
can change the beat and number of measures for the pattern (

➝ p. 21 – 22).

• If desired, the duration of the precount can be changed, or it can be turned off (

➝ p. 48).

Adjust the tempo if necessary.

The pattern tempo can be changed at any time. For recording a difficult phrase, it might be
helpful to temporarily reduce the tempo.

7.

Tap the pads in accordance with the metronome sound.

The sound of the respective pad is heard, and it is recorded for the duration set with the
quantize value. You can verify the current position in the pattern by checking the display.
When the end of the pattern is reached, the recording loops back to the beginning and
continues, allowing you to add to the recording as often as desired. (If necessary, use the
[PAD BANK] key to change the pad bank.)

8.

To temporarily pause pattern recording, press the [REC] key while real-time
recording is in progress.

The [REC] key starts to flash. If you hit a pad in this condition, the sound will be heard, but
it is not recorded. This is useful to check the phrasing and sound before actually recording.
To resume recording, press the [REC] key once more.

9.

To erase the sound from a specific pad, push the pad while holding down the
[DELETE/ERASE] key.

While the key is held down, the sound from that pad is erased from the pattern.

10.

When recording is completed, press the [STOP] key.

• If a MIDI clock signal is being received, real-time recording is not possible. For details, please

refer to page 44.

•When there is not enough remaining free memory in the MRT-3, the indication "FULL" appears on

the display, and further recording is not possible. Erase unneeded patterns.

Pattern Step Recording

This section describes step recording, which allows you to enter and record each sound separately,
step by step, while the MRT-3 is in the stop condition. Even without mastering how to play the
pads in real time, you can easily create complex drum and bass patterns. And you don't need to
stop there, because you can even create patterns that would be impossible to play in real time.

For step recording, you select the shortest note that is to be used as unit, and you create the pattern
by pressing a pad (note) or the [REC] key (rest) for each step.
For example, to create the following bass drum pattern with step recording, select an eighth note
as smallest unit and make the entry as follows:

When the end of a pattern is reached, it loops automatically back to the beginning, allowing you
to add other instrument sounds, to complete the pattern. By hitting two pads at the same time, you
can enter two sounds in the same position.

1.

In pattern mode, select an empty user pattern.

2.

If required, select the kit for recording.

The kit selection procedure is the same as for manual play (➝p. 12).

3.

Press the [FUNCTION] key and then pad 3 (QUANTIZE).

The current quantize setting appears on the display. The minimum unit (shortest note) for
step recording is determined by this setting.

The quantize setting applies to all patterns.

4.

Use the [VALUE +/-] keys to set the quantize value (shortest note to be recorded).

Creating Your Own Kit (Kit Mode)

This section describes how to line up user patterns in a desired order to create an entire song. This
mode of operation is called the song mode.

What Is a Song?

A song is a programmed sequence of preset patterns or user patterns that are played automatically.
A song consists of multiple slots (called "steps"), each of which contains one pattern. The
maximum length of a song is 99 steps. The maximum number of songs that can be stored in the
MRT-3 is 99. (The actual number of available steps and songs will depend on the number of
distinct sounds in user patterns and the number of steps in other songs.)

Note that the number of steps is not equal to the number of measures. The length of each step
depends on the pattern that is contained in the step. For example, in the song in the above
illustration, if the length of the pattern U01 is 2 measures and the length of patterns U02 and U03
1 measure, the song will look as follows.

Besides the pattern number, each song step can contain the following information.

Settings for entire song

• Song kit: ••••••••••••••••••••••• Number of kit to be used for entire song

•Master tempo:••••••••••••••• Tempo information for entire song

Settings for individual patterns

•Tempo change: ••••••••••••• Information for changing the tempo within the song

•Volume change: •••••••••••• Information for changing the volume within the song

It is also possible to not specify a song kit and memorize individual kits for each pattern. In this
case, the kit will be switched together with the pattern.

This function allows you to produce the sound of a specific pad when you operate the foot
switch. This is convenient for example to play the sound of a bass drum with your foot.
To select this function, press the [FUNCTION] key and then pad 4 (FOOT SW). Then
press the foot switch, release it, and use the [PAD BANK] key and pads 1 – 7 to select the
pad sound to assign to the foot switch. (The intensity with which you hit the pad when
making the selection is also memorized.)
The display shows the pad number as A1 – A7, B1 – B7.

• Use FS01 to switch between the sounds of two pads

This function allows you to assign two drum or percussion sounds to a pad and use the
foot switch to control which sound is produced. This is convenient for example to switch
between open and closed hi-hat sound with your foot.

To select this function, press the [FUNCTION] key and then pad 4 (FOOT SW). Then press
the foot switch and release it. Finally, push the first pad, followed by the second pad.
The number of the first pad is shown on the first two digits of the display, and the number

The foot switch can be made to function in the same way as the [PLAY] key. Pressing the
foot switch then toggles between play and pause: "Start play"

➝

"Pause" ➝"Resume
play" etc.
To select this function, press the [FUNCTION] key and then pad 4 (FOOT SW). Then
press the [PLAY] key (the indication "Cont" appears on the display).

• Use FS01 to control start/stop

The foot switch can be made to function in the same way as the [PLAY] and [STOP]
keys. Pressing the foot switch then toggles between play and stop: "Start play"

➝

"Stop"

➝

"Start play from beginning" etc.
To select this function, press the [FUNCTION] key and then pad 4 (FOOT SW). Then
press the [STOP] key (the indication "Strt" appears on the display).

Synchronizing Playback With an External Device

You can synchronize operation of the MRT-3 to an external device with MIDI OUT, such as a
MIDI sequencer or recorder. The MRT-3 then performs pattern or song playback using the tempo
supplied by the external device.

1.

Connect the MIDI OUT jack of the MIDI sequencer/recorder to the [MIDI IN]
connector of the MRT-3, using a MIDI cable.

The illustration shows an example for connecting the Multitrak Recording Studio ZOOM
MRS-4 to the MRT-3. If you connect the output of the MRT-3 to the AUX IN jack of the
MRS-4, as shown here, the MRT-3 can be used to supply a dedicated rhythm track without
taking up any audio tracks of the MRS-4

Make sure that the external MIDI sequencer can send MIDI Clock, Start, Stop, and Continue signals.

2.

In pattern mode, press the [FUNCTION] key and then pad 6 (MIDI).

The clock currently used by the MRT-3 is shown on the display.
The meaning of the indication is as follows.

•Int (Internal)

The MRT-3 operates with its internal clock (default setting). This is the setting for using
the MRT-3 on its own.

• Midi (MIDI clock)

The MRT-3 receives a clock signal from an external source (MIDI sequencer/recorder
etc.) and synchronizes the playback tempo to this signal. Transport operations (playback
start, stop, restart) and locate operations (moving the current position) can also be
controlled remotely from the external device.

• rMt (Remote)

The MRT-3 operates on its internal clock, as with "Int". However, transport operations
only can be controlled remotely from an external device.

Other Functions

3.

Use the [VALUE +/-] keys to select the "Midi" or "rMt" setting.

When wishing to control the tempo, transport operations, and locate operations all from the
external device, select "Midi". In this case, the internal tempo settings of the MRT-3 have no
effect. Set the tempo at the external device.

When wishing to control only transport operations from the external device, select "rMt". In
this case, the internal tempo settings of the MRT-3 are active. (Because the tempo of the
MRT-3 and the tempo of the external device are not synchronized, position matching within
a song for playback is not possible.)

4.

Press the [FUNCTION] key once more.

The unit returns to the previous mode.

5.

Select a song or pattern for synchronized playback.

6.

Start playback at the MIDI sequencer/recorder.

• When "Midi" is selected as clock source

The MRT-3 starts playback from the start of the sequence/song in sync with the MIDI
clock tempo. When the MIDI sequencer/recorder is stopped, the MRT-3 also stops.
When the MIDI sequencer/recorder is moved to a position within the song for playback,
the MRT-3 also starts playback from that position.

• When "rMt" is selected as clock source

The MRT-3 starts playback from the start of the sequence/song, using its internal tempo
setting. When the MIDI sequencer/recorder is stopped, the MRT-3 also stops.
If the MIDI sequencer/recorder is moved to a position within the song for playback, the
MRT-3 cannot start playback from that position.

Playing MRT-3 Sounds From an External MIDI
Component

Using an external MIDI sequencer or MIDI keyboard, you can play the sound sources of the
MRT-3. To do this, the MIDI receive channel setting of the MRT-3 must match the MIDI send
channel of the external device.

1.

Connect the MIDI OUT jack of the MIDI sequencer or similar to the [MIDI IN]
connector of the MRT-3, using a MIDI cable.

2.

In pattern mode, press the [FUNCTION] key and then pad 6 (MIDI).

The clock currently used by the MRT-3 is shown on the display.

3.

Press and hold the [KIT] key.

While the [KIT] key is being pressed, the display shows the current MIDI receive channel
setting (default setting: 10).

4.

Use the [VALUE +/-] keys to select the MIDI receive channel.

The MIDI receive channel can be set to OFF (no MIDI messages are received), or 1 – 16.

5.

When the setting is complete, press the [FUNCTION] key again.

The unit returns to the previous mode.

Setting the Pattern/Song Playback Swing

You can adjust the swing amount (rhythm flourish) for playback of patterns and songs. This
setting affects all patterns and songs.

1.

In pattern mode or song mode, press the [FUNCTION] key and then pad 7
(SWING).

The current swing amount setting is shown on the display (default setting: 50).

2.

Use the [VALUE +/-] keys to adjust the swing amount.

The setting range is 50 – 75. Raising the setting from the default of 50 (no swing) increases
the interval between upbeat and downbeat in a measure, resulting in a swinging rhythm.

If necessary, press the [PLAY] key to play a pattern and check the effect.

3.

When the setting is complete, press the [FUNCTION] key again.

The unit returns to the previous mode.
