STEP1 Press the [PATTERN] key.
This activates the pattern mode. The [PATTERN] key LED lights up.
![ZOOM RT234 - STEP1 Press the [PATTERN] key. - 1](/content/2025/01/152302/images/8e657a9bf78a7a67041bdf45cd3e716d70e149d0d0d6da9f4d079e310d6b9f3b.jpg)
STEP2 Press the [DRUM A] key of the [KIT/TRACK SELECT] keys.
During manual play, you use the [KIT/TRACK SELECT] keys to select the desired drum kit or bass program. (The LED of the selected key lights up.) Pressing the [DRUM A], [DRUM B], or [DRUM C] key selects drum kit A - C. Pressing the [BASS] key selects the bass program. In this example, let's use drum kit A.
![ZOOM RT234 - STEP2 Press the [DRUM A] key of the [KIT/TRACK SELECT] keys. - 1](/content/2025/01/152302/images/bf0f2a5816c9505d38c20e181311d465c1f96508b5ea03d13dfb4b2fc1067515.jpg)
STEP3 Tap one of the pads.
The LED of the pad lights up briefly and the sound assigned in the drum kit to that pad is heard. The volume changes according to how strongly you tap the pad.


When the [BASS] key is pressed in step 1, a bass program can be played, but there is a difference in how the pads operate. With a drum kit, the sound plays through even if the pad is released immediately. With a bass program, the sound continues only as long as the pad is pressed.
STEP4 Tap a pad while holding the [REPEAT/STEP] key down.
The sound will be produced continuously for as long as the pad is pressed. The repetition speed depends on the tempo.
![ZOOM RT234 - STEP4 Tap a pad while holding the [REPEAT/STEP] key down. - 1](/content/2025/01/152302/images/eff31561e516f3a3cf5dca639cdcd5635a254702f8815953d9ed0b533ffc745a.jpg)
You can adjust the interval for repeated play. See the "Quantize" section on page 44.
![ZOOM RT234 - STEP4 Tap a pad while holding the [REPEAT/STEP] key down. - 2](/content/2025/01/152302/images/fbf004617d8cde63d7fb6d2c9848987e8965f4d92af2bc3cbafa89003b32d83b.jpg)
Using the slider (modify function)
By moving the [SOUND JAMMER] slider while using the pads, you can change the pitch, volume, or tone continuously.

STEP1
Use the [JAM FUNCTION] key to select the sound parameter that you want to change with the slider.
With each push of the key, the setting cycles through the following setting, and the corresponding LED lights up: PITCH VOLUME SOUND CHANGE Out.


STEP2
Tap the pad while moving the [SOUND JAMMER] slider.
- When PITCH is selected: The slider center position is the reference pitch, and moving the slider shifts the pitch up or down. The adjustment range depends on the sound type.
- When VOLUME is selected: Moving the slider changes the volume. The pad tapping intensity has no effect in this case.
- When SOUND CHANGE is selected: In the center position of the slider, there is no change in the sound. Moving the slider up or down selects variation 1, variation 2 etc. The available variations depend on the sound type.

[Sound JAMMER]

- Only one sound parameter (pitch, volume, or tone) can be changed at a time. When the parameter is switched, the previous parameter returns to its original setting.
- When the sound parameter is switched, the slider becomes active only after passing the position corresponding to the current value. For example, if the VOLUME parameter is selected with the slider set to 0, the volume will not become zero right away. The volume starts to change only after the slider is moved and has passed the current volume position ([SOUND JAMMER] slider LED flashes at this point).
- If you have assigned PITCH to the [SOUND JAMMER] slider on the bass track, moving the slider while tapping the pad will produce sound with different pitches. Moving the slider from the bottom to the top will shift the pitch in the same order as the pitches assigned to pads 1 to 13.
Selecting a kit/program for manual play
For manual play, you can select among 100 drum kits, 24 percussion/SFX kits, and 50 bass programs.


Press one of the [KIT/TRACK SELECT] keys to select the track, and hold the key down.
The current kit/program number is shown on the [VALUE] display.

Available drum kit types are printed on the panel.

[DRUM A]

While holding the [KIT/TRACK SELECT] key down, use the [VALUE UP/DOWN] keys to select a kit.
The [VALUE UP/DOWN] keys switch the kit number shown on the [VALUE] display by 1 up or down, and the selected kit changes accordingly.


- Keeping a [VALUE UP/DOWN] key depressed changes numbers continuously.
- You can also select a kit by holding the [KIT/TRACK SELECT] key down and moving the [SOUND JAMMER] slider. The slider changes numbers continuously.


Tap the pads to check the new sound.

In pattern mode, the [KIT/TRACK SELECT] keys serve to select a track. While one of the keys is pressed, the number of the kit/program allocated to the corresponding track is shown on the [VALUE] display.


While holding the [KIT/TRACK SELECT] key down, use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to change the kit.
The track is switched to the sounds of the new kit.


By repeating steps 1 and 2, you can change the kits assigned to the other tracks.

Changing the kit/program is also possible while playing a pattern.

- When the kit/program is changed in a user pattern, the new kit/program setting will be stored when the pattern is stored.
- The kit/program of a preset pattern cannot be changed.
Changing the tempo of pattern playback
When playing a pattern in pattern mode, the playback tempo for the pattern can be varied over the range of 40 - 250 BPM (BPM = beats per minute, using quarter notes).


Press the [TEMPO] key.
The [VALUE] display shows the current tempo for about 2 seconds.

When the tempo has been set to the desired value, release the [TEMPO] key.
The [VALUE] display shows the current tempo for about 2 seconds.
![ZOOM RT234 - Press the [TEMPO] key. - 5](/content/2025/01/152302/images/2af34756cad263e36577a24ef36aae95c902b5a72b5e8f674bb39391c709f151.jpg)
To input the tempo for manual play, tap the [TEMPO] key twice in the desired interval (tap tempo input).
While a pattern is paused or playing, the [TEMPO] key can be tapped twice to input a quarter note interval. When creating a pattern, this makes it easy to set the desired tempo.
![ZOOM RT234 - Press the [TEMPO] key. - 6](/content/2025/01/152302/images/bd4855e1f072f80c4459f76f99d5720be70b5c491f935b248381de7160c8f5ba.jpg)

The tempo set in pattern mode applies to all patterns. It cannot be changed for an individual pattern.
Pattern Recording (Real-Time Recording)
The RhythmTrak 234 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). The procedure for real-time recording of a drum track and bass track is described below.
Deleting an unnecessary pattern
As shipped from the factory, the user patterns 01 - 99 of the RhythmTrak...234 contain the same patterns as the preset patterns P01 - P99. Therefore you must first delete a pattern if you wish to write your own pattern to a user pattern slot. This is done as follows.

STEP1 In pattern mode, select the user pattern (01 - 99) you want to erase.
After erasing a pattern, the unit remembers the drum kit and bass program type and other values, until the pattern is changed. Therefore we recommend that you choose a pattern whose image resembles the new one you want to create.


The preset patterns (P01 - P99) cannot be erased.
STEP2 Press the [DELETE/ERASE] key.
The [DELETE/ERASE] key LED and the pattern number are flashing, and the indication "dEL?" appears on the [VALUE] display.
If you wish to delete all patterns, see page 47.
![ZOOM RT234 - STEP2 Press the [DELETE/ERASE] key. - 1](/content/2025/01/152302/images/a0495c2f613e5f204b047371f8bd7327fade96b2c6908bededab55123fbe7f09.jpg)
[DELETE/ERASE]
STEP3 When wishing to go ahead with the delete process, press the [DELETE/ERASE] key once more. Otherwise press the [STOP] key.
When the delete process is completed, the unit returns to the pattern mode with the empty user pattern selected. At this time, the [VALUE] display shows "----".
If the delete process was canceled, the unit returns to the pattern mode with the original user pattern selected.
![ZOOM RT234 - STEP3 When wishing to go ahead with the delete process, press the [DELETE/ERASE] key once more. Otherwise press the [STOP] key. - 1](/content/2025/01/152302/images/14b0ef099afaf3496cd69794dcfb8b17d45ae80eecafd013a849ec5c2923dfe4.jpg)
![ZOOM RT234 - STEP3 When wishing to go ahead with the delete process, press the [DELETE/ERASE] key once more. Otherwise press the [STOP] key. - 2](/content/2025/01/152302/images/80951de0859141d6367f53df3fc4c34a92a4691bf8dd11fd4b1cf4d7d75fd558.jpg)
If you erase a user pattern that you have created yourself, you will not be able to restore it. Make sure that you really want to erase the pattern before carrying out step 2. When wishing to return all user patterns to the factory default condition, please refer to page 52.
Real-time recording of a drum track
Real-time recording refers to the process of playing the pads while listening to a metronome sound and recording what you play. First, let's record drum tracks in real time.

STEP1 In pattern mode, select an empty user pattern (01 - 99).
When a pattern that contains nothing is selected, the [VALUE] display shows only "----".

You cannot record over a preset pattern.

STEP2 Press the [FUNCTION] key and then pad 6 (QUANTIZE).
The [VALUE] 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 want to use for the pattern, recording can be carried out while automatically maintaining precise timing. You can also turn the quantize function off, to retain the human touch that is characterized by slightly irregular timing.
![ZOOM RT234 - STEP2 Press the [FUNCTION] key and then pad 6 (QUANTIZE). - 1](/content/2025/01/152302/images/abf1a690f7afd52b64a2859dc1e3a93879c501e2dd6b5518e1f83b4f49eae142.jpg)
![ZOOM RT234 - STEP2 Press the [FUNCTION] key and then pad 6 (QUANTIZE). - 2](/content/2025/01/152302/images/cce27c739c256e252893190e40d99c2f28fc131e398e8c1f714e2f9af5c54d70.jpg)
The [FUNCTION] key is used to make various settings for the RhythmTrak...234. For details, please refer to page 41.
![ZOOM RT234 - STEP2 Press the [FUNCTION] key and then pad 6 (QUANTIZE). - 3](/content/2025/01/152302/images/a377956bf96fd442c0a6e943d6f8fd378122d541024ec4d5e05d5f04a22282b7.jpg)
STEP3 Use the [VALUE UP/DOWN] key or the [SOUND JAMMER] slider to set the quantize value (shortest note to be recorded).
4 Quarter note
16 Sixteenth note
48 ...Thirty-second triplet note
8 .Eighth note
24 Sixteenth triplet note
Hi .......Quantize function off
12 .Eighth triplet note
32 Thirty-second note
STEP4 Press the [FUNCTION] key once more.
The new quantize value is set and the unit returns to the pattern mode.
![ZOOM RT234 - STEP4 Press the [FUNCTION] key once more. - 1](/content/2025/01/152302/images/8dd5d999aefee9736e42b0fc3d91d40ea878c3dece473bf17671f970f5c5af6f.jpg)
After recording is completed, it is also possible to change the quantize value and record again on the same track. For example, after recording bass drum and snare drum using quarter notes, you may want to record a hi-hat sequence with sixteenth notes.
![ZOOM RT234 - STEP4 Press the [FUNCTION] key once more. - 2](/content/2025/01/152302/images/3fc6f1d60ae49a954f903b31a1229720afb0297b7055bdff61be609ba5bd4010.jpg)
While holding the [KIT/TRACK SELECT] key for the desired track down, use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to select the kit for the selected track.
For recording a pattern, the [KIT/TRACK SELECT] keys are used to select the track. In this example, select the [DRUM A] key. While the [DRUM A] key is held down, the currently selected kit number is shown on the [VALUE] display.
![ZOOM RT234 - STEP4 Press the [FUNCTION] key once more. - 3](/content/2025/01/152302/images/6f27422e80786618273a85959486c26c90ef0c8c6f95206aaf7bfb258378dd3a.jpg)

In a user pattern, the kit/program is stored for each track. If the kit/program was changed, the last selected kit/program will be stored.
STEP6 While holding the [REC] key down, press the [START] key.
The [REC] key LED and [START] key LED light up and the [TEMPO] key LED flashes. The metronome sound starts.
![ZOOM RT234 - STEP6 While holding the [REC] key down, press the [START] key. - 1](/content/2025/01/152302/images/4f156df93d2544b0b44090f6562241381aec7e25b8470c0b2adcfed4fa71a8d3.jpg)
If not specified otherwise, an empty pattern is set to a beat of 4/4 and a length of 2 measures. These settings can be changed, as described on page 44-45.
![ZOOM RT234 - STEP6 While holding the [REC] key down, press the [START] key. - 2](/content/2025/01/152302/images/a1f7682fc414903668c1e7ce79c90f244f2e8db14bd1611690d11c8b17e4efd3.jpg)
STEP7 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 [VALUE] 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.

When the [REC] key is pressed during real-time recording, the [REC] key LED starts to flash and pattern recording is suspended. In this condition, tapping the pads will produce sound, but it is not recorded. This is useful to check phrasing and sound before actually recording. To resume recording, press the [REC] key once more.
While the key is held down, the sound from that pad is erased from the pattern. To erase the entire track, push the respective [KIT/TRACK SELECT] key while holding the [DELETE/ERASE] key down. While both keys are held down, all sounds in that track are erased.

[DELETE/ERASE]


By holding the [REPEAT/STEP] key down while hitting a pad, an ongoing sound can be created. Moving the [SOUND JAMMER] slider while hitting a pad changes the pitch, volume, or tone (please refer to page 47). In this case, the change is effective only while the pad is being pushed. If the [SOUND JAMMER] slider is moved while the pad is released, the change will not be recorded.
STEP10 Record drum tracks B and C using the same procedure.
STEP11 When recording is completed, press the [STOP] key.
Operation of the RhythmTrak 234 stops.

- If a MIDI clock signal is being received, real-time recording is not possible. For details, please refer to page 47.
- The sound from external MIDI components cannot be recorded.
Real-time recording of a bass track
Next, let's add a bass track to the drum track pattern recorded in the previous section.

STEP1 Press the [BASS] key of the [KIT/TRACK SELECT] keys and hold the key down.
The bass track is selected for recording.
![ZOOM RT234 - STEP1 Press the [BASS] key of the [KIT/TRACK SELECT] keys and hold the key down. - 1](/content/2025/01/152302/images/c76114cad379cca6b9e8152f87eb6378b1f08bd6924d2a4f30df4513b363805b.jpg)
STEP2 [SOUND JAMMER] slider to select a bass program. If necessary, change the quantize and tempo settings.

The bass program can also be changed during recording.
STEP3 Press the [FUNCTION] key and then pad 1 (BASS KEY).
To record a bass track, you must first assign the pitches from the bass pattern to the pads. Pressing the [FUNCTION] key followed by pad 1 (BASS KEY) enables pitch setting for each pad. The [FUNCTION] key LED lights up and the [VALUE] display shows the pitch name assigned to pad 1.
![ZOOM RT234 - STEP3 Press the [FUNCTION] key and then pad 1 (BASS KEY). - 1](/content/2025/01/152302/images/75fbcda5f5f24fe54b169c08ef1e0409b0f50d75138f69f334657d944d72f294.jpg)

- Also if a pattern was erased, the pitches assigned to the pads in the previous pattern are retained. When wishing to use these as is, steps 3 - 7 can be omitted.
- In the factory default condition, all user patterns have E2 (the lowest note of a 4-string bass) assigned to pad 1.
While the pad is being pressed, the assigned pitch name (E1 - A4) is shown on the VALUE indicator.
![ZOOM RT234 - STEP3 Press the [FUNCTION] key and then pad 1 (BASS KEY). - 3](/content/2025/01/152302/images/b660316c3bc0476b4c095dbac0dd8f5ff9d41891747b966137bb660b1cbc89a4.jpg)

When pad 2 - 13 is released, the pitch name assigned to pad 1 is shown again. This pitch is used as reference when shifting the entire pitch of all pads up or down in semitone steps. Take care not to inadvertently change this pitch.
![ZOOM RT234 - STEP3 Press the [FUNCTION] key and then pad 1 (BASS KEY). - 5](/content/2025/01/152302/images/cfe5b96fdbdab4f6a97f965cdd9c68421d0f19cec2d9ad7ac691ea9e6592d7c0.jpg)
STEP5
While holding the pad down, use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to change the pitch assigned to the pad.
The illustration below shows an example for assigning an E minor and E major scale to the pads.
There are many possibilities for assigning pitch names. We recommend that you try out various approaches to find the one that is best suited to the bass pattern that you want to record.

Example with E minor scale assigned to pads

Example with E major scale assigned to pads

STEP6
To shift the pitch of all pads, operate the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider while no pad is pushed.
When the pitch assigned to pad 1 is changed, the pitch of pads 2 - 13 also changes accordingly. For example, if the E minor scale is assigned and you shift pad 1 from "E 2" to "A 2", the A minor scale will be assigned to the pads.
Example with A minor scale assigned to pads

STEP7
When the pitch has been assigned as desired, press the [FUNCTION] key once more.
The [FUNCTION] key LED goes out.
STEP8
While holding the [REC] key down, press the [START] key.
The [REC] key LED and [START] key LED light up and the [TEMPO] key LED flashes. The already recorded drum tracks are played back.
STEP9
Tap the pads in accordance with the metronome sound.
As opposed to drum track recording, the bass track records for the length of which you press a pad. For example, to record the following sequence, hold the pad to which A2 has been assigned and the pad to which E2 has been assigned down for the length of a quarter note each.



When the [REC] key is pressed during real-time recording, the [REC] key LED starts to flash and pattern recording is suspended. In this condition, tapping the pads will produce sound, but it is not recorded. This is useful to check phrasing and sound before actually recording.
STEP10
To erase the sound from a specific pad, push the pad while holding the [DELETE/ERASE] key down.
While the key is held down, the sound from that pad is erased from the pattern. To erase the entire bass track, push the [BASS] key of the [KIT/TRACK SELECT] keys while holding the [DELETE/ERASE] key down. While both keys are held down, the bass track is erased.

[DELETE/ERASE]



STEP11
When recording is completed, press the [STOP] key.
Pattern Recording (Step Recording)
This section describes step recording, which is another recording type that is possible with the RhythmTrak ...234.
What is step recording?
Step recording allows you to enter and record each sound separately, step by step, while the RhythmTrak …234 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 of a drum track, you select the shortest note that is to be used as unit, and you create the pattern by pressing a pad (note) or the [REPEAT/STEP] 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 for example snare and hi-hat separately, to complete the pattern. By pushing 2 pads at the same time, you can enter 2 sounds in the same position.
For step recording of a bass track, the procedure is slightly different, because unlike for the drum track, the pitch and duration of the sound must be specified. The fact that tapping a pad gives the shortest-unit note and pushing the [REPEAT/STEP] key gives the shortest-unit rest is the same. The pitch is determined by which pad you push. The length is determined by holding down the pad down and pressing the [REPEAT/STEP] key multiple times. Each push of the [REPEAT/STEP] key increases the duration of the sound by the shortest unit note.
For example, to enter the following bass phrase, select an eighth note as smallest unit and make the entry as follows:

Step recording of a drum track
This section describes how to record drum tracks A - C using step recording.

STEP1 In pattern mode, select an empty user pattern.

When wishing to use a pattern where a track has already been recorded, the pattern must be erased first. Please refer to page 18.
STEP2 Use the [KIT/TRACK SELECT] keys and [VALUE UP/DOWN] keys to select the track and kit for recording.
The selection method is the same as for real-time recording. In this example, press the [DRUM A] key of the [KIT/TRACK SELECT] keys.
![ZOOM RT234 - STEP2 Use the [KIT/TRACK SELECT] keys and [VALUE UP/DOWN] keys to select the track and kit for recording. - 1](/content/2025/01/152302/images/ace883e4ad7ca6287945e8fd9ddfc99f1b9869d7020def865fff1d4db32134a9.jpg)
Selecting drum track B or C allows recording in the same way.
STEP3 Press the [FUNCTION] key and then pad 6 (QUANTIZE).
The current quantize setting appears on the [VALUE] display. The minimum unit (shortest note) for step recording is determined by this setting.
![ZOOM RT234 - STEP3 Press the [FUNCTION] key and then pad 6 (QUANTIZE). - 1](/content/2025/01/152302/images/8c1766e198b67f4505428f365ee57d4d45ed9ef812d6ea6b47059b6e8a671047.jpg)
STEP4 Use the [VALUE UP/DOWN] key or the [SOUND JAMMER] slider to set the quantize value, and then press the [FUNCTION] key once more.
4 .Quarter note
16 Sixteenth note
48 ... Thirty-second triplet note
8 .Eighth note

For details on the [FUNCTION] key, please refer to page 41.
The [REC] key LED and [START] key LED light up, indicating that the RhythmTrak …234 is ready for recording.
![ZOOM RT234 - STEP4 Use the [VALUE UP/DOWN] key or the [SOUND JAMMER] slider to set the quantize value, and then press the [FUNCTION] key once more. - 2](/content/2025/01/152302/images/d62953fa5ddc677ff659a4ee9cd57a0fa0ffd39ad6149b5f82e9e8c5f0276e1c.jpg)
STEP6
To enter a note, press the pad corresponding to the desired sound. To enter a rest, press the [REPEAT/STEP] key.
For example, tapping the [KICK] pad will enter a bass drum note (the [KICK] pad LED flashes briefly). The current position of the pattern then advances by one unit. The tapping intensity will of course also be recorded.
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.

- The [VALUE] display shows the current position in the pattern (measure/beat).
- By moving the [SOUND JAMMER] slider while tapping the pad, you can change the pitch, volume, or tone.
STEP7
To erase a sound, use the [REPEAT/STEP] key to move to the desired position. Then press the corresponding pad while holding down the [DELETE/ERASE] key.
As you move the position with the [REPEAT/STEP] key, the LED of a pad that has been input for the current position lights up. Pressing the pad while holding the [DELETE/ERASE] key down causes the LED to go out and the sound will be erased.


During step recording, erasing the entire track is not possible.
STEP8
When recording is completed, press the [STOP] key.
The [REC] key LED goes out, and step recording ends.
STEP9
To record drum track B or C, repeat steps 3 - 8.

If step 4 is carried out without pressing the [FUNCTION] key, the quantize value of the pattern already recorded in that track will also be changed. For example, if step recording was carried out with sixteenth notes and the quantize value was then changed to quarter notes, the pattern already recorded will also be changed to quarter notes if the [REC] key is pushed without pressing the [FUNCTION] key.

Step recording of a bass track
Now let's add a bass track to the drum tracks recorded as described in the previous section. Because pitch and duration must be specified for the bass track, the procedure is slightly different from step recording of the drum track.

STEP1 Press the [BASS] key of the [KIT/TRACK SELECT] keys.
The bass track is selected.
STEP2 Use the [BASS] key and the [VALUE UP/DOWN] keys to select a kit.
STEP3 Press the [FUNCTION] key and then pad 6 (QUANTIZE).
Use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to set the quantize value (smallest unit for recording). Then press the [FUNCTION] key again.
For details on the quantize value, please refer to page 28.
STEP5 Press the [REC] key.
The [REC] key LED and [START] key LED light up, indicating that the RhythmTrak ……234 is ready for recording.
![ZOOM RT234 - STEP5 Press the [REC] key. - 1](/content/2025/01/152302/images/8c121264ff7dd0bdb079ac9c4b2aa5ead90b605e20809e272093117fdcc3127c.jpg)
If step 4 is carried out without pressing the [FUNCTION] key, the quantize value of the pattern already recorded in that track will also be changed. For example, if step recording of a bass track was carried out with sixteenth notes and the quantize value was then changed to quarter notes, the pattern already recorded will also be changed to quarter notes if the [REC] key is pushed without pressing the [FUNCTION] key.
STEP6 Press the desired pad and/or the [REPEAT/STEP] key to enter the desired note or rest with the desired duration.
For step recording of the bass track, you perform one of three actions:
- Enter the minimum unit note: Briefly tap the pad and release it. A note of the selected minimum duration and the pitch assigned to that pad is entered, and the position proceeds to the next step.
- Enter the minimum unit rest: Briefly tap the [REPEAT/STEP] key and release it. A rest of the selected minimum duration is entered, and the position proceeds to the next step.

When recording is completed, press the [STOP] key.
The [REC] key LED goes out, and step recording ends.
Pattern Copy
The current pattern (preset pattern or user pattern) can be copied to another user pattern. This is useful for example when wishing to change only a part of pattern, such as adding percussion or changing only the bass track phrasing. The copy source can be either a preset pattern or a user pattern, but because preset patterns are read-only, the copy destination can only be a user pattern.

STEP1 In pattern mode, select the pattern to be used as the copy source.
STEP2 Press the [INSERT/COPY] key.
The [INSERT/COPY] key LED flashes and the current pattern is selected as the copy source.

STEP3 Use the [UP/DOWN] keys or the [SOUND JAMMER] slider to select a user pattern (01 - 99) as the copy target.

When the copy is executed, the existing contents of the user pattern selected as the copy target will be erased. Make sure that the pattern you have selected is one that you don't mind erasing.

STEP4 To execute the copy process, press the [INSERT/COPY] key. When wishing to cancel the process, press the [STOP] key.
When copying is completed, the unit returns to the pattern mode with the copy target pattern being selected.
If copying was canceled, the unit returns to the pattern mode with the copy source pattern being selected.
Creating Songs (Song Mode)
This section describes how to line up user patterns in a desired order to create the backing for an entire song. This mode of operation is called the song mode.
What is a song?
A song is a sequence of user patterns (preset patterns cannot be used). A song consists of multiple slots (called "steps") each of which contains one pattern. The maximum length of a song is 255 steps. The maximum number of songs that can be stored in the RhythmTrak ...234 is 99. (The actual number of available steps and songs will depend on the number of distinct sounds used for user patterns and other songs.) In song mode, you can change also the tempo and volume during a song.

NOTE
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.
Besides the pattern number, each song step can contain the following settings:
- Tempo change: In song mode, the tempo is stored individually for each song. (The tempo is set with the [TEMPO] key, as described on page 17.) Using this tempo as reference, the tempo for each step can be varied in the range from -30 to 0 (no change) to +30 BPM (beats per minute = number of quarter notes per minute).
- Volume: The volume of the pattern as contained in the step can be set in the range from 0 (no change) to -30.
- Transpose: The bass track can be transposed in semitone steps in the range from -6 to 0 (no change) to +6.

- Pressing the [VALUE DOWN] key turns off the sound of the currently selected track.
![ZOOM RT234 - STEP10 To listen to the song, press the [START] key. - 5](/content/2025/01/152302/images/99cbd540e75a74e22c0cd44e4618175d812333ab09dc4ef038b54b5e0f5eb4c1.jpg)
When you select an empty pattern that you have already deleted per the procedure described on page 18, the BASS KEY, MIX, kit number, and bass program will use the settings that were obtained before you deleted the pattern. TIME SIG will be set to "4" and BAR LENGTH will be set to "2".
If you play back a song that includes an empty pattern step, the playback will stop at the empty pattern step.
If a song includes a rest, not an empty pattern step, the song will continue playing after the rest pattern.
You can create a rest pattern by pressing the [REC] key in an empty pattern. A rest pattern stores the settings of the track BASS key (only for the bass track), MIX, TIME SIG, BAR LENGTH, and kit number/bass program when you press the [REC] key.
STEP11 Press the [STOP] key when wishing to terminate playback.
The LED goes out and the song returns to the start position.

Also during playback of a song, you can use the pads for manual play. However, modifications made with the [SOUND JAMMER] slider have no effect on the playback sound of the song.
Editing a song
This section describes how you can alter parameters such as tempo or volume for a song that has already been recorded.

STEP1 In song mode, select the song to which you want to make alterations.
STEP2 Press the [REC] key.
The [REC] key LED lights up, and song editing becomes possible.
STEP3 Use the [VALUE UP/DOWN] keys to select the step where you want to make an alteration.
The [VALUE] display shows the step number and the [SONG/PATTERN] display shows the pattern number.

STEP4 Choose the type of alteration by pressing one of the following keys:
- [TEMPO] key: to change the tempo of the pattern
- Pad 2 (MIX): To set the pattern volume
- Pad 1 (BASS KEY): To transpose the bass track
The current setting of the selected parameter is shown on the [VALUE] display.

STEP5 While holding down the pad whose parameter you want to change, use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to set the value.
The adjustment range for the various parameters is as follows.
- Tempo change: -30 to 0 to 30 BPM
Volume: 0 to -30 - Transpose: -6 to 0 to 6 (in semitones)

STEP6 Repeat steps 3 - 5 until all desired parameters are set.
Deleting a song
When you wish to delete a song, for example to make room for new recordings, proceed as follows.

STEP1 In song mode, select the song you want to delete.
STEP2 Press the [DELETE/ERASE] key.
The [DELETE/ERASE] key LED and the song number flash, and the [VALUE] display shows "dEL?"

STEP3 To delete the song, press the [DELETE/ERASE] key. To cancel the process, press the [STOP] key.
When deleting is carried out, the unit returns to the song mode with an empty song selected.
When deleting is canceled, the unit returns to the song mode with the original song selected.

Once deleted, a song cannot be restored. Proceed with care to prevent inadvertently deleting a song.
Using Pads to Play Patterns (Groove Play)
This section describes the groove play mode. In this mode, the 13 pads are used to play patterns assigned to them. This allows quick switching between patterns during a performance. Up to 4 patterns can be played simultaneously, letting you for example play two patterns with a different beat, or the same pattern twice, shifted by 1 beat, to create a complex rhythm.

STEP1 Press the [SONG] key and the [PATTERN] together.
The RhythmTrak …234 switches to groove play mode, and the [SONG] key LED and [PATTERN] key LED light up.
STEP2 Try out the sound by pressing any pad.
In the factory default condition, the RhythmTrak …234 has 13 patterns specially designed for groove play assigned to pads 1 - 13. If a pad is held down, the assigned pattern plays repeatedly. The intensity with which the pad is hit controls the overall pattern volume. The pattern number is shown on the [VALUE] display.

STEP3 To change the pattern assigned to a pad, hold the pad down and use the [VALUE UP/DOWN] keys to select the new pattern.
You can select a groove pattern (G01 - G99) or user pattern (01 - 99). If you select "00", the drum kit and base programs assigned to each pad will sound.
![ZOOM RT234 - STEP3 To change the pattern assigned to a pad, hold the pad down and use the [VALUE UP/DOWN] keys to select the new pattern. - 1](/content/2025/01/152302/images/3607cace37d0bda42491e2dc7e33dc023ebacb55e5297588d645ab395f63a611.jpg)
![ZOOM RT234 - STEP3 To change the pattern assigned to a pad, hold the pad down and use the [VALUE UP/DOWN] keys to select the new pattern. - 2](/content/2025/01/152302/images/c010a7e26245fd1944d4cbbbe6ec71e0adb094c0d2f16706dbe0b8cacdeceea9.jpg)
The patterns assigned to the pads are retained also while the unit is turned off.
STEP4 To repeat a pattern even when the pad is released, hit the pad while holding the [REPEAT/STEP] key down.
The pattern will then be looped even when you release the pad. To stop the loop, hit the pad once more. The unit returns to normal groove play.
To quickly change the pattern assigned to the pad, move the [SOUND JAMMER] slider while pressing and holding down the [REC] key and the corresponding pad.
![ZOOM RT234 - STEP4 To repeat a pattern even when the pad is released, hit the pad while holding the [REPEAT/STEP] key down. - 1](/content/2025/01/152302/images/7103742f2d5382e001cbb2d9a82283a9a18a9355504c96ca2f8f8957507a60f2.jpg)
STEP5 To play several patterns simultaneously, push several pads together.
Up to 4 patterns can be played simultaneously, using the same tempo. Slightly shifting the timing when you hit the pads is also possible.

If 5 or more pads are pushed, only the patterns of the last 4 pads will be played.

- In groove mode, the [START] and [STOP] key can be used to start and stop the currently selected song.
- During groove playback, pad operation (press/release) is detected using the quantize value (shortest note) as the detection interval. This is aimed at matching the timing to other grooves and songs played at the same time. Playing with a fast timing is therefore facilitated by choosing a low quantize value. To play with small timing shifts, choose a higher quantize setting.


STEP6
To continuously change the pitch, volume, or tone of the pattern, you can use the [SOUND JAMMER] slider.
The [SOUND JAMMER] slider allows sound modification also in groove play mode. The slider affects all tracks selected with the [KIT/TRACK SELECT] keys.


Use the [JAM FUNCTION] key to select the sound parameter that you want to change with the [SOUND JAMMER] slider. For details, please refer to page 13.
STEP7
When wishing to terminate the groove play mode, press the [SONG] key or [PATTERN] key.
The RhythmTrak…234 returns to the song mode or pattern mode.

If "00" is selected as pattern number in step 3, the sounds originally assigned to the pads (depending on the currently selected kit/program) are played.
FUNCTION Key Settings
The [FUNCTION] key is used to make various settings for the RhythmTrak ...234. The 13 pads on the top panel of the RhythmTrak ...234 are also used to select setting items for the [FUNCTION] key.

Setting Range: 435 - 445 (Default value: 440)
Allows tuning the bass pitch with the [VALUE UP/DOWN] keys in the range of 435Hz - 445Hz
Setting the beat of a pattern (TIME SIG)
Setting Range: 2, 3, 4
Use the [VALUE UP/DOWN] keys to set the beat for the pattern to 2 (2/4 beat), 3 (3/4 beat), or 4 (4/4 beat). Changing the beat of an already recorded pattern is also possible, but the recorded sound will change as follows. Proceed with care, especially when making the beat shorter.
Choosing a longer beat than the current beat
A blank space with the length of the additional beat is added to each measure.
Choosing a shorter beat than the current beat
The excess duration of each measure is cut off. Once the [FUNCTION] key is pressed to accept the setting, it will not be possible to restore the cut-off sections.

The RhythmTrak …234 stores this setting for each pattern individually.
Setting the pre-count (PRE COUNT)
Setting Range: 0, 1, 2, PAd (Default value: 1)
The pre-count (number of metronome ticks before the start of pattern real-time recording) can be turned on and off, and the number of measures can be set with the [VALUE UP/DOWN] keys.
The settings have the following meaning.
0: Real-time recording starts immediately when the [START] key is pressed.
1: Real-time recording starts after 1 measure has been counted.
2: Real-time recording starts after 2 measures have been counted.
PAd: The unit goes into recording standby mode when the [START] key is pressed, and recording starts when any pad is pressed.
Setting the pattern resolution (QUANTIZE)
Setting Range: 4, 8, 12, 16, 24, 32, 48, Hi (Default value: 16)
Sets the quantize value (shortest note) for the pattern. After selecting the item, set the value with the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider.
The quantize setting affects the following four functions:
- Shortest note for real-time recording
- Shortest note for step recording
-
Sound interval when [REPEAT/STEP] key is used together with pad for continuous repetition
-
Pad push/release detection timing during groove play
The following 9 settings are available for the quantize value.
4.Quarter note
16 Sixteenth note
48 ....Thirty-second triplet note
8 .Eighth note
24 Sixteenth triplet note
Hi .......Quantize function off
12 .Eighth triplet note
32 .........Thirty-second note
During step recording:
1 tick (1/96 quarter note)

- Even when the quantize value is set to Hi, the [REPEAT/STEP] key interval is a thirty-second note.
- The quantize value cannot be set separately for each track.
Setting the metronome volume level (CLICK VOL)
Setting Range: 0 - 99 (Default value: 70)
The volume level of the metronome click sound heard during real-time recording can be adjusted with the [VALUE UP/DOWN] keys.
This setting applies to all patterns.
Setting the number of measures for a pattern (BAR LENGTH)
Setting Range: 1 - 99
Sets the length of the pattern in the range from 1 - 99 measures. Changing the length of an already recorded pattern is also possible, but the recorded sound will change as follows. Proceed with care, especially when making the number of measures smaller.

The RhythmTrak …234 stores this setting for each pattern individually.
Making the number of measures larger
Blank measures are added to the end of the pattern.
Making the number of measures smaller
The excess measures at the end of the pattern are cut off. Once the [FUNCTION] key is pressed to accept the setting, it will not be possible to restore the cut-off measures.
Selecting the foot switch/foot pedal function (CTRL ASSIGN)
Sets the function of the foot pedal FP01 or foot switch FS01 connected to the [CTRL1 IN]/[CTRL2 IN] jacks on the rear panel.

The intensity with which you tap the pad to set up the FS01 determines the volume level of the sound produced when you press the FS01. The volume is affected by the pad sensitivity setting (PAD SENS).
■ When FP01 is connected
Press the [FUNCTION] key and then pad 9 [CTRL ASSIGN], and move the pedal to enable the setting. After the function is selected with the [JAM FUNCTION] key, the FP01 can then be used in
the same way as the [SOUND JAMMER] slider to continuously adjust pitch, volume, or tone (see page 13). The selected function is shown on the [VALUE] display as "Pit", "Vol", or "SndC".
It is not possible to set the [SOUND JAMMER] control and the pedal connected to [CTRL1 IN] or [CTRL2 IN] to a different function.
■ When FS01 is connected
Press any one of pads 1 - 13, the [START] key, [STOP] key, [REPEAT] key, [TEMPO] key, [VALUE UP] key, or [VALUE DOWN] key while pushing down the FS01 to assign the function to the FS01.
- When one pad is pressed
The FS01 operates like that pad, activating the sound assigned to the pad. This can be used for example to play the bass drum manually during a performance.
- When two pads are pressed in sequence
The FS01 can be used to switch the sound of the pad selected first. When the FS01 is depressed, the sound of this pad is heard, and when the FS01 is not depressed, the sound of the other pad is played. (This can be used for example to switch between open hi-hat and closed hi-hat during a performance.) Operating the FS01 will activate the sound of the first pad, even if that pad is not pressed.
- When the [START] key is pressed
Pressing the FS01 will pause or resume playback.
- When the [STOP] key is pressed
Pressing the FS01 will stop playback or start playback from the top of the pattern or song.

When the FP01 or FS01 is not connected or when it is not pressed at the time when the [FUNCTION] key is operated, the above procedure has no effect.
Setting the playback swing amount (SWING)
Setting Range: 50 - 75 (Default value: 50)
This setting controls the swing amount (rhythm flourish). Higher values result in more pronounced swing. This item influences only the playback timing of the pattern. It does not affect the recorded data of the pattern.
Setting the pad sensitivity (PAD SENS)
Setting Range: Soft, MEd, Loud, LItE, norM, HArd, Ehrd (Default value: norM)
The [VALUE UP/DOWN] keys are used to set the pad sensitivity.
The following 7 settings are available.
- Soft (Fixed Soft): Gives a soft sound regardless of the tapping intensity.
- MEd (Fixed Medium): Gives a medium sound regardless of the tapping intensity.
- Loud (Fixed Loud): Gives a loud sound regardless of the tapping intensity.
- Lite (Light): This setting gives the highest sensitivity.
norM (Normal): This setting gives medium sensitivity. - HArd (Hard): This setting gives low sensitivity.
- Ehrd (Extra Hard): This setting gives the lowest sensitivity. To achieve a loud sound, the pads must be hit very hard.
Setting Range: -192 to +192 (Default value: 0)
Shifts the playback timing of a specific track in the currently selected pattern back or forth in 1-tick units (1/96 of a quarter note). The maximum shift is 2 measures. After selecting this item, use the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider to set the shift value. The recorded data of the pattern is updated when the function is terminated.
When set to a negative value (-)
The playback timing of the selected track is shifted forward. The pattern shifted forward is deleted.
When set to a positive value (+)
The playback timing of the selected track is shifted backwards. The pattern shifted backwards is deleted.
Proceed with care, because once the [FUNCTION] key is used to terminate the setting, it cannot be undone.
Setting MIDI input on/off (MIDI)
Setting Range: Int, Midi (Default value: Int)
When this item is set to "Midi", the RhythmTrak ...234 can receive the following MIDI messages from external components.
MIDI clock
Start
-
Stop
-
Continue

When this item is set to "Midi", real-time recording is not possible.
Setting the MIDI receive channel for each track (MIDI)
Setting Range: 0, 1 - 16 (drum track) 0, 1 - 16, Auto (bass track)
(Default values,drum track A:10,drum track B:0,drum track C:0,bass track:9)
This item sets the MIDI channel for each track. Available settings for drum tracks are 0 (not received) and 1 - 16. Available settings for the bass track are 0 (not received), 1 - 16, and Auto.
"Auto" is a special setting for playing standard GM sound source compatible MIDI files. When the RhythmTrak ...234 receives a GM sound source bass select message, it automatically switches the bass track to that MIDI channel.
To set the MIDI receive channel, hold down the [KIT/TRACK SELECT] key of the desired track and set the value with the [VALUE UP/DOWN] keys or the [SOUND JAMMER] slider. This setting is made individually for each track.
Deleting all patterns
Press and release the [FUNCTION] key. The LED of the [FUNCTION] key will flash. Press the [DELETE] key. The indicator "dEL?AL" will appear. Press the [DELETE] key again to delete the data for all user patterns.
