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 RT-223.
- Power requirements

Since power consumption of this unit is fairly high, we recommend the use of an AC adapter whenever possible. When powering the unit from batteries, use only alkaline types.
[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.
- During lightning or when not using the unit for an extended period, disconnect the AC adapter from the AC outlet.
[Battery operation]
- Use four conventional IEC R6 (size AA) batteries (alkaline).
- The RT-223 cannot be used for recharging.
- Pay close attention to the labelling of the battery to make sure you choose the correct type.
- When not using the unit for an extended period, remove the batteries from the unit.
- If battery 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

To prevent the risk of fire, electric shock or malfunction, avoid using your RT-223 in environments where it will be exposed to:
Extreme temperatures
- Heat sources such as radiators or stoves
High humidity or moisture
- Excessive dust or sand
- Excessive vibration or shock
Handling

- Never place objects filled with liquids, such as vases, on the RT-223 since this can cause electric shock.
- Do not place naked flame sources, such as lighted candles, on the RT-223 since this can cause fire.

The RT-223 is a precision instrument. Do not exert undue pressure on the keys and other controls. Also take care not to drop the unit, and do not subject it to shock or excessive pressure.
- Connecting cables and input and output jacks

You should always turn off the power to the RT-223 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all connection cables and the power cord before moving the RT-223.
- Alterations

Never open the case of the RT-223 or attempt to modify the product in any way since this can result in damage to the unit.
Volume

Do not use the RT-223 at a loud volume for a long time since this can cause hearing impairment.
Usage Precautions
- Electrical interference
For safety considerations, the RT-223 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 RT-223, as the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the RT-223 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 RT-223. 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.

Introduction
Thank you for selecting the ZOOM RhythmTrak RT-223 (hereafter simply called the "RT-223"). The RT-223 is a sophisticated product with the following features.
- Highly compact drum/bass machine
The RT-223 is small enough to fit in the pocket of a guitar case. But it has enough muscle to play a full rhythm accompaniment with super realistic drum and bass sounds. You can use it as a personal metronome during practice, or as your rhythm section during a live performance and when making a demo tape.
- Perfectly simple operation
Even if you have never used a drum machine or sequencer before, you will feel comfortable with the RT-223 right away.
- Great selection of preset patterns
The RT-223 can store 511 different patterns (including patterns that you have created yourself). Out of the box, it comes with a wide choice of representative patterns that will you get started in no time.
- Program the accompaniment to an entire song
You can line up multiple patterns in the intended order to create the rhythm accompaniment for a full song. Besides step input, where you specify elements such as pattern number, volume, and tempo one by one, the RT-223 also supports the innovative FAST input method developed by ZOOM.
Groove play mode lets you play patterns like a DJ
Assigning patterns to the pads on the top panel lets you change patterns simply by tapping the pads. Great for live performances and for DJ use.
- Create your original kits
The RT-223 comes with built-in drum kits and bass programs for a variety of musical genres. What's more, you can create your own drum kits by combining drum sounds at will.
- Two types of effects
The drum kit/bass program sound can be processed by two kinds of effects (COMP EQ and REVERB). The REVERB effect allows adjusting
the effect depth for each drum sound individually.
- Jam function for selecting patterns with a foot switch
Connect a foot switch to have even more control over play start/stop and switching patterns. While playing your instrument, you can set fill-ins or breaks or return to the main theme after improvising for any length. This is great for those lively jam sessions.
Built-in metronome function
The metronome is convenient for scale practice or rhythm practice. In addition to the standard beat, you can also use mixed beat settings such as 5-beat and 7-beat.
- Input jack for connecting an external sound source
Connect an instrument processed with a multi-effect such as the ZOOM GFX-1 and mix it with the RT-223 signal to produce impressive sounding output.
- Control various functions with a foot switch
A connected foot switch can be used to start/stop a pattern or change the tempo while keeping your hands free. Alternatively, push the foot switch down to kick a virtual bass drum, or switch between hi-hat open/close.
- Compatible with MIDI synchronization
The MIDI IN connector allows an external MIDI keyboard or other device to play the sounds of the RT-223. It is also possible to synchronize the RT-223 to the MIDI clock from a MIDI sequencer.
Please take the time to read this manual carefully so as to get the most out of your RT-223 and to ensure optimum performance and reliability. Retain this manual, the warranty card and all other documentation for future reference.

The RT-223 assigns various sounds or pitches to the pads, depending on the currently selected drum kit/bass program. Play the pads to discover the realistic sounds offered by the RT-223.
1. Press the [PATTERN] key.
![ZOOM RT-223 - Press the [PATTERN] key. - 1](/content/2025/01/152244/images/84bd53837a4baeae4e45da6da87f2a220a2d2afd82fa993f4fc77f919132992c.jpg)
This activates the pattern mode. The [PATTERN] key lights up.
2. Press the [DRUM] key.
![ZOOM RT-223 - Press the [DRUM] key. - 1](/content/2025/01/152244/images/c9ede71655245e7498e384444d94b76b0a0c10fd6720181e1ceda443ba29b107.jpg)
The [DRUM] key lights up, and you can play the drum kit using the pads.
During manual play, you use the [DRUM] key and [BASS] key to select the drum kit or bass program. (The selected key lights up.)
3. 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.
HINT
When the [BASS] key is pressed in step 2, 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.
4. Press the [BANK] key.
![ZOOM RT-223 - Press the [BANK] key. - 1](/content/2025/01/152244/images/218ea451832d8fe7c1d93dd8c5adc830b8ad87fd608ffccadb3e8a8fef2b147b.jpg)
Each time you press the [BANK] key, the set of sounds assigned to the pads (pad bank) changes. The RT-223 gives you a choice of three pad banks.
HINT
When a bass program is selected, pressing the [BANK] key changes the pitch range of the bass sound.
5. To play the sound of a pad repeatedly, hold down the [REPEAT/STEP] key while pushing the pad.

If necessary, specify a root for the pattern that suits the entered bass phrase. The BASS KEY setting (p. 64) is used to set the root information for the pattern. For patterns that are not to be used in a song or for patterns where the bass track is empty, making the setting is not required.
Entering Patterns Using Step Input
This section describes step recording, which is another recording type that is possible with the RT-223.
What is step recording?
Step recording allows you to enter and record each sound separately, step by step, while the RT-223 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.
For step recording of a drum track, you first select the shortest note that is to be used as a unit (length of one step). Then you specify the drum instrument by pressing a pad and the [REPEAT/STEP] key. The note is entered, and input proceeds to the next step. If you press the [REPEAT/STEP] key without pressing a pad, a rest is entered.
For example, to enter the following bass drum pattern by step input, select an eighth note as smallest unit, and then make the input in the following order, as shown in Figure 1.
[KICK] [STEP] [STEP] [STEP] [KICK] [STEP] [STEP] [STEP] [STEP] [KICK] [STEP]
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 two pads at the same time, you can enter two 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. For the drum track, every pad produces the sound of a different instrument, but for the bass track, the pitch is determined by which pad you push.
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, but the fact that a parameter called "duration" is added when entering a note is different. Even when the step length is the same, the actual duration of each note can be varied individually. To enter the bass phrase shown in Figure 2, select an eighth note as smallest unit and make the entry as shown, while varying the duration.


Step recording of drum track
This section describes how to record the drum track using step recording.
1. In pattern mode, select an empty user pattern, and select a drum kit, as necessary.
The selection method for pattern and drum kit is the same as in real-time recording ( p. 22).
When you select an empty pattern, the indication "EMPTY" appears on the display.
HINT
If there is no empty pattern, delete an unneeded pattern first ( ,33)
2. Press the [FUNCTION] key and then pad 5 (QUANTIZE).
The current quantize setting appears on the display. The minimum unit (shortest note) for step recording is determined by this setting.

HINT
If necessary, specify a root for the pattern that suits the entered bass phrase. The BASS KEY setting (p. 64) is used to set the root information for the pattern. For patterns that are not to be used in a song or for patterns where the bass track is empty, making the setting is not required.
Editing a Pattern
This section explains how to edit patterns.
Copying a pattern/ Returning a pattern to the factory default condition
You can copy the currently selected pattern to another position. This is useful to change only a part of a pattern, such as changing the bass track phrasing while keeping the drum track.
Patterns that were preprogrammed at the factory (patterns 0 - 439) can be returned to their original condition by the copy process described below.
NOTE
When the copy is executed, the existing contents of the pattern selected as copy target will be erased. Use this function with care.
1. Press the [PATTERN] key.
![ZOOM RT-223 - Press the [PATTERN] key. - 1](/content/2025/01/152244/images/5b17850c3bc0b92570ce0915e46e6884b7cfbbe2370481d89025f99f272f6731.jpg)

Symbols: (space), () * + - /
- Repeat step 3 until the name is complete.
- When name input is completed, press the [EXIT] key.
The name is accepted, and the RT-223 returns to the pattern mode.
Creating Songs (Song Mode)
This section explains what a song in the RT-223 is and how to create songs.
What is a song?
A song in terms of the RT-223 is a sequence of patterns (a number of measures of drum track and bass track) lined up in play order, to provide the backing for an entire musical piece (see illustration below). The maximum number of songs that can be stored in the RT-223 is 100.
A song can be input in three different ways.
- Step input
With this method, you start at the beginning of the song and proceed in discrete steps, specifying the pattern to play and the number of measures for each step. This method is suitable for detailed, manual work on a song.
Real-time input
With this method, you first assign the patterns to the pads and then play the patterns in real time. This method is suitable for quick and intuitive input of a song.
- FAST (Formula Assisted Song Translator)
This method uses simple formulas to specify rhythm pattern playback from start to end. The result is written out as a song in a single operation. This method is suitable for songs with repeated patterns and cases where the configuration of the entire song has been decided beforehand.
HINT
The resulting song is the same, regardless of
which input method was used. After creating a song with FAST input or real-time input, you can still fine-tune it with step input.
Besides pattern information, a song also contains so-called event data (tempo, beat, volume and other information, see page 42). Use step input to enter event information.
Creating a song using step input
This section explains how to create a song by lining up patterns one by one.
1. Press the [SONG] key.
The [SONG] key lights up and the RT-223 goes into song mode. The name and number of the currently selected song are shown on the display.
![ZOOM RT-223 - Press the [SONG] key. - 1](/content/2025/01/152244/images/7af32048a6b0c726888fd187484350382aab905078d86a75e7cce7fe71aa7361.jpg)
2. Use the VALUE [+] /[-] keys to select a song for which "EMPTY" is shown.
HINT
- If there is no empty song, you may have to erase a song that is no longer needed ( ,47)

- Keeping a VALUE [+]/[-] key depressed changes numbers continuously.
- To change numbers quickly, hold down one of the VALUE [+] /[-] keys and press the other key. The numbers will change rapidly.
3. Press the REC [●] key.
The REC [ ] key lights up and the display changes as follows. This screen is used for step input.
![ZOOM RT-223 - Press the REC [●] key. - 1](/content/2025/01/152244/images/0c92fda2e22bf92ac85109b6495ca23975a37dd242ee91b61b363b6d300f4f91.jpg)
The "End" indication means that the song is currently at the end position. For an empty song where no information has been input, the start and "End" point are identical.
![ZOOM RT-223 - Press the REC [●] key. - 2](/content/2025/01/152244/images/dce791bd9c93bd5ccaccbbbf6305692b693c067fd525c3e07fa89c6810c82449.jpg)
4. Press the [INSERT/COPY] key.
The display changes as follows, and pattern input becomes possible.
![ZOOM RT-223 - Press the [INSERT/COPY] key. - 1](/content/2025/01/152244/images/7949466071e9d578e0302ce66a0bb8e01ae9a6deffd1ad1ebf10d61fce7f7284.jpg)
5. Use the VALUE [+] /[-] keys to select the pattern to input.
The selected pattern name appears on the display.
6. Use the cursor left/right keys to set the number of measures for the pattern.
If the selected number is higher than the original number of measures for the pattern, the same
pattern will be repeated. If a smaller number is selected, the sound will switch to the next pattern partway through.
7. When the setting is complete, press the [INSERT/COPY] key.
The pattern with the specified number of measures is inserted, and the display shows the new end position of the song. This means that the "End" indication has now moved to the last measure.
![ZOOM RT-223 - When the setting is complete, press the [INSERT/COPY] key. - 1](/content/2025/01/152244/images/c7e33c1770200ab99e4b6bfa7730b4e093980fe139543f411b0de18ddda4f79f.jpg)
During step input of a song, the input position can be moved by the following actions.
- Jumping to event positions
Use the VALUE [+]/[-] keys. With each push of a key, the input position moves to the next or previous event point.
- Moving in measure units
Use the cursor left/right keys. With each push of a key, the input position moves to the next or previous measure.
- Moving in sixteenth note units
Use the [REPEAT/STEP] key. With each push of the key, the input position moves in sixteenth note units.
8. Repeat steps 4 - 7 to enter all required pattern information.
To edit an entered pattern, you can perform one of the following actions.
- To reselect a pattern
Use the cursor left/right keys to move to the point where the respective pattern information is input, and press the [EDIT] key. The event editing screen appears. Now use the cursor left/right keys
to select "PTN", and use the VALUE [+]/[-] keys to select a new pattern number. To return to the step input screen, press the [EXIT] key. For details on event input/editing, see page 42.
When the pattern is switched within a measure, the new pattern will normally start playing at this point from the beginning. However, you can also have the new pattern start playing from a point other than the beginning. This lets you do things such as inserting the fill-in portion of the new pattern at the third beat of a measure.
To do this, press the [REPEAT] key when the new pattern number is displayed, so that a dot (. appears next to the pattern number.

Pressing the [REPEAT] key once more turns the dot off. The pattern will be playing from the start.
To insert a new pattern in a song
Move to the point where the pattern is to be inserted and carry out steps 4 - 7. This inserts a pattern at the current position, and shifts all later patterns back by the duration of the inserted pattern.

To delete a pattern
Use the cursor left/right keys to move to the pattern to delete, and press the [EDIT] key to switch to the event editing screen. Now use the cursor left/right keys to select "PTN", and press the [DELETE/ERASE] key. When pattern information is deleted, the "PTN" indication
changes to PTN", which means that the preceding pattern will continue to play. For details on event input/editing, see page 42.

To delete a specific measure
Move to the start of the measure to delete, and press the [DELETE/ERASE] key. The measure is deleted and subsequent events are shifted by one measure forward.

9. To terminate song step input, press the STOP [■] key.
![ZOOM RT-223 - To terminate song step input, press the STOP [■] key. - 1](/content/2025/01/152244/images/ba688f7dde89540c8756fb36c356e789165c24f56a1a68d79b22d3f510e53941.jpg)
The REC [ ] key goes out, and song step input is terminated.
Creating a song using real-time input
In song mode, you can assign different patterns to the 13 pads and play the patterns with the pads. This allows you to play the accompaniment to a performance by hitting the pads to switch patterns. It can also be used to line up patterns for a song in real time, as described below.
HINT
The operation of pads in song mode resembles that of groove play mode ( p. 48). However, in song mode, it is not possible to play several patterns simultaneously. Switching patterns is only available in measure or beat units.
■Assigning patterns to pads
This section describes how to assign to the pads the patterns to use in a song.
NOTE
The pattern assignment made in song mode and that made in groove play mode ( p. 48) are separate. These settings do not influence each other.
1. Press the [SONG] key to activate song mode, and use the VALUE [+] /[-] keys to select a song for which "EMPTY" is shown.
HINT

The pad lights up, showing that it is selected for operation.
3. Use the cursor left/right keys to select a parameter.

The parameters and their setting ranges that are available for each pad are shown in the table below.
| Parameter type | Description | Setting range |
| PATTERN | Number and name assigned to the pad | 000 – 511 |
| ROOT | Bass track root | E – D# |
| NEXT | Operation when switching a pattern | P00 – P12 |
| F00 – F12 | ||
| StP |
If the root set for a pattern with BASS KEY ( p. 64) and the root set for the song are different, the bass phrase is transposed to match the root entered for the song. For example, if the pattern root is set to C for the phrase "G - A - B", and the song root is set to D, the resulting phrase will be "A - B- C#".
The NEXT parameter determines the operation when a pad is pressed to switch a pattern and when a pattern has finished playing.
P00-P12
When the pattern is finished, the pattern of the specified pad (00 - 09: pads 0 - 9, 10: pad ([+] , 11: pad [x], 12: pad ([()]) ) will be called up.
F00-F12
The pattern changes at the change of the beat, and when the pattern is finished, the pattern of the specified pad plays.
StP
Playback stops at the end of the pattern.
4. Use the VALUE [+] /[-] keys to change the setting value.
Repeat steps 2 - 4 to make settings for the other pads in the same way.
5. When the setting is complete, press the [BANK] key or the [EXIT] key.
The unit returns to song mode.
Using the pads to enter a song in real mode
This section describes how to enter a song in real time by tapping pads to which patterns have been assigned.
1. In song mode, select the song for which to perform real-time input.
HINT
- Song numbers 0 - 9 already have patterns assigned to the pads.
- You can assign patterns to pads yourself. For details, see page 37.
2. Press the PLAY [▶] key while holding down the REC [●] key.
![ZOOM RT-223 - Press the PLAY [▶] key while holding down the REC [●] key. - 1](/content/2025/01/152244/images/8248b42950936e2ccec5870c39c43e09e7b13d9b9d52a31cc3b825cb737c7a18.jpg)
The REC [ ] key and PLAY [ ] key light up, and the song is ready for real-time input.
3. Hit the pad to which the first pattern is assigned.
As soon as you hit the pad, real-time recording starts, and the pattern plays. The current measure and beat and the current song number are shown on the display.

4. To switch the pattern, hit the next pad during the last measure before the intended switch.
The pattern assigned to the pad goes into standby, and the pattern is switched at the start of the next measure. The pad that is in standby mode flashes.

NOTE
If you hit a pad whose NEXT parameter ( p. 38) is set to "F00 - F12", the pattern will be switched not at the measure boundary but at the beat boundary.
5. Enter the remaining patterns in the same way as described for step 4.
6. To terminate song real-time input, press the STOP [■] key.
The REC [ ] key and PLAY [ ] key go out, and song real-time input is completed.
HINT
- To assign an ending pattern to a pad, set the NEXT parameter to "StP", so that real-time input will automatically be stopped.
- A song created with real-time input can later be edited with step input.
Creating a song using FAST input
The FAST (Formula Assisted Song Translator) method developed by ZOOM uses simple formulas to specify patterns for an entire song, which is then written in a single operation.
The formula symbols are entered using the 13 pads. The function of each pad during FAST input is shown in the illustration below.

The basic rules for creating a rhythm pattern sequence are as follows.
Line up patterns
Use the "+" symbol to line up rhythm patterns. For example, entering 0 + 1 + 2 will result in the following rhythm pattern play sequence.
| PATTERN 0 | PATTERN 1 | PATTERN 2 |
- Repeat patterns
Use the "x" (multiplication) symbol to specify pattern repetitions. As in normal arithmetic, "x" takes precedence over "+" For example, entering 0 + 1 × 2 + 2 will result in the following rhythm pattern play sequence.
| PATTERN 0 | PATTERN 1 | PATTERN 1 | PATTERN 2 |
- Repeat multiple patterns
Use the “(” and “)” symbols (opening and closing brackets) to link a group of patterns for repetition. Formulas enclosed in brackets take precedence over other formulas. For example, entering 0 + (1 + 2)× 2 + 3 will result in the following rhythm pattern play sequence.
| PATTERN 0 | PATTERN 1 | PATTERN 2 |
| PATTERN 1 | PATTERN 2 | PATTERN 3 |
An example for creating the rhythm pattern sequence 0 + (1 + 2)× 3 is shown below.

HINT
If the formula exceeds seven digits, earlier character/symbol entries are scrolled off the display. To see the scrolled part, use the cursor left/right keys to move the display position.
NOTE
- The FAST method can only be used to write a song in one go, from beginning to end. Entering patterns partly into the song is not possible.
- To edit a song that was written with this method, edit the formula and then write the entire song again, or use step input.
1. Press the [SONG] key to activate song mode, and use the VALUE [+] /[-] keys to select a song for which "EMPTY" is shown.
NOTE
If you select an existing song and write it out using FAST input, the entire previous content of the song will be overwritten. Use this function with care.
2. Press the [FUNCTION] key and then the REC [●] key.
![ZOOM RT-223 - Press the [FUNCTION] key and then the REC [●] key. - 1](/content/2025/01/152244/images/59a5a144c3a3d1599f308801fd7a175d77b7908fa13f8e6a216a33615056edb8.jpg)
The indication "FAST" appears briefly on the display. Then an underline cursor appears at the first character position. FAST input is now possible.
![ZOOM RT-223 - Press the [FUNCTION] key and then the REC [●] key. - 2](/content/2025/01/152244/images/fbff4685833b7fd0fd3f65e55a2989b450ae80e404d069a3500b92fc6c050b4e.jpg)
3. Use the pads to enter a formula.
The input method is explained on page 40.

If you make a mistake during input, you can correct it as follows.
- Deleting a number/symbol
Use the cursor left/right keys to move the flashing segment to the number/symbol to delete, and press the [DELETE/ERASE] key.
- Inserting a number/symbol
Use the cursor left/right keys to move the flashing segment to the point where you want to insert a number or symbol, and input the new number/symbol.
4. When formula input is completed, press the [FUNCTION] key.
The song is written and FAST input terminates.
NOTE
If the entered formula contains a syntax error, the indication "SYTXERR" appears on the display when you press the [FUNCTION] key. After a while, the formula input screen appears again. Correct the wrong part, and perform the write operation again.
Entering event information
Besides pattern information, you can enter various other information (called event data) for a song, such as tempo, beat, and volume. You can gradually fade out the volume or switch the sound of the drum kit or bass program at any point in the song. To add event data to a song for which patterns have already been input, use the step input method.
1. In song mode, select the song for which you want to input an event.
2. Press the REC [●] key.
The REC [ ] key lights up, and step input for the song becomes possible.
3. Move to the position where you want to enter event information.
For information on moving the current position, see page 35.
At a point where any kind of event information
including pattern information is input, the "EVENT" indication is shown (see illustration below).

HINT
By using the VALUE [+]/[-] keys during step input of a song, you can move directly to previous or later events.
4. Press the [EDIT] key.
You can now select the event type to enter/edit.
![ZOOM RT-223 - Press the [EDIT] key. - 1](/content/2025/01/152244/images/69992c2aeef5e8f51b1c0f7ee1f55c3bdcd9bdbe04095e1641a2ed96819409ac.jpg)

5. Use the cursor left/right keys to select the type of event to enter.

Available event types are shown in the following table.
| Event type | Description | Setting range |
| PTN | Pattern number | 000 – 511 |
| TIMSIG | Beat | 1 – 8 (1/4 – 8/4) |
| ROOT | Bass track root | E – D# |
| TEMPO | Tempo | 40 – 250 |
| DR VOL | Drum track volume | 0 – 15 |
| BS VOL | Bass track volume | 0 – 15 |
| DR KIT | Drum kit | 0 – 126 |
| BS PRG | Bass program | 0 – 11 |
If you select an event for which information has already been input at the current position, the event name and setting value are shown on the display. (By pressing the VALUE [+]/[-] keys in this condition, you can change the setting.)

If you select an event for which no information has been input at the current position, the indication xxx (where xxx is the event name) is shown. This means that the preceding information for the same event type remains valid. The following illustration shows an example for the display when the TEMPO event is selected.

HINT
- If you enter tempo information at the beginning of a song, the song will always play at that tempo, regardless of current tempo settings.
- If the root set for a pattern with BASS KEY ( p. 64) and the root set for the song are different, the bass phrase is transposed to match the root entered for the song. For example, if the pattern root is set to C for the phrase "G - A - B", and the song root is set to D, the resulting phrase will be "A - B- C#".
6. Use the VALUE [+] /[-] keys to enter the setting value.
When you specify the setting value with the VALUE [+]/[-] keys, the indication “ xxx” (where xxx is the event name) changes to the event name only. This indicates that new event information has been input at the current position.
![ZOOM RT-223 - Use the VALUE [+] /[-] keys to enter the setting value. - 1](/content/2025/01/152244/images/ac18e3dbbf76585db2d24a2e6fdb0ca9838946f81404efe2755e1b97a11b7a3a.jpg)

Using Pads to Play Patterns (Groove Play Mode)
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 play two patterns with a different beat, or the same pattern twice, shifted by 1 beat, to create a complex rhythm.
1. Press the [SONG] key and [PATTERN] key simultaneously.
![ZOOM RT-223 - Press the [SONG] key and [PATTERN] key simultaneously. - 1](/content/2025/01/152244/images/40d7b79867db0ae875cf4544b38fd248f8e8ddf0ecbc8ac75676c92dee1a68b3.jpg)
The RT-223 switches to groove play mode. The [SONG] key and [PATTERN] key are both lit. The display shows the name and number of the currently selected song.
NOTE
In groove play mode, all patterns are played with the tempo of the currently selected song. If required, you can enter a desired tempo at the beginning of the song ( ,42)
2. Try out the sound by pressing any pad.

In the factory default condition, the RT-223 has 13 patterns specially designed for groove play assigned to the pads. If a pad is held down, the assigned pattern plays repeatedly. The intensity with which the pad is hit controls the overall pattern volume. While the pad is pressed, the pattern name and number are shown on the display.

3. To change the pattern assigned to a pad, hold the pad down and use the VALUE [+] /[-] keys to select the new pattern.
![ZOOM RT-223 - To change the pattern assigned to a pad, hold the pad down and use the VALUE [+] /[-] keys to select the new pattern. - 1](/content/2025/01/152244/images/566f050be4e746c43ef6c3add7512bceed2073c313a4a7cc9e01bdee7301c326.jpg)
If the VALUE [-] key is pressed while "0" is displayed, or if the VALUE [+] key is pressed while "510" is displayed, the display indication changes to "PAD". Instead of a pattern, a pad for which "PAD" is selected will play the single sound originally allocated to the pad (such as kick drum or snare).
NOTE
- The pattern assignments made in groove play and those made in song mode ( p, 37) are separate and independent of each other.
- The patterns assigned to the pads are retained also while the unit is turned off.
4. To repeat a pattern even when the pad is released, hit the pad while holding down the [REPEAT/STEP] key.
![ZOOM RT-223 - To repeat a pattern even when the pad is released, hit the pad while holding down the [REPEAT/STEP] key. - 1](/content/2025/01/152244/images/3991f7552237652f144c532cf5179165a48df97cbba2ee2de5c913e7c9c4ad64.jpg)
The pattern will be looped even when you release the pad. To stop the loop, hit the pad once more. The unit returns to normal groove play.
5. 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.
NOTE
If 5 or more pads are pushed, only the patterns of the last 4 pads will be played.
6. To play a song while groove play continues in the background, use the VALUE [+] /[-] keys to select the song number and press the PLAY [▶] key.
![ZOOM RT-223 - To play a song while groove play continues in the background, use the VALUE [+] /[-] keys to select the song number and press the PLAY [▶] key. - 1](/content/2025/01/152244/images/72c7f8a9fd37a688307f5e90137d8be6373f0fdbe295fb4a54284aa8af5a553e.jpg)
In groove play mode, the PLAY [▶] key and STOP [■] key can be used to start or stop the currently selected song. Also while a song is playing, up to four patterns assigned to pads can be played.
HINT
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 fast timing is therefore facilitated by choosing a low quantize value. To play with small timing shifts, choose a higher quantize setting.
NOTE
In groove play mode, song editing is not possible.
7. To terminate the groove play mode, press the [SONG] key or [PATTERN] key.

From the single drum and percussion sounds stored in the RT-223, select the sound to assign to the pad. Each sound is identified by a number. For a list of available sounds, see the appendix at the end of this manual.
PITCH
This lets you fine-tune the pitch of the drum sound assigned to each pad. The setting range is -7.9 - 0 (reference pitch) - +7.9. The setting can be made in increments of 0.1 (1/10 semitone).
- INSTLVL (Instrument level)
Sets the volume for each pad in the range from 0 to 15.
PAN (Panning)
Sets the left/right position of each pad when stereo playback is carried out. The setting range is L63 (fully left) - 0 (center) - R63 (fully right).
VGROUP (Voice group)
This setting determines the type of action when the same pad is hit in succession (PL/MN), and the group to which the pad belongs (0 - 7). The setting range is PL0 - PL7 and MN0 - MN7.
If you select PL for a pad, the previous sound of the pad will keep playing in addition to the new sound when you hit the pad in succession. If you select MN for a pad, the previous sound of the pad will stop, and only the new sound is heard when you hit the pad in succession.


The numeric settings 0 - 7 determine the group of a pad (0: no group, 1 - 7: group 1 - 7). The sounds of pads that are in the same group will not be produced together. By assigning the pads for open hi-hat and closed hi-hat to the same group, the open hi-hat sound will be suppressed when you activate the closed hi-hat sound, resulting in a natural effect.
The group number 0 - 7 applies both to PL and MN. Therefore pads PL1 and MN1 will not produce sound together.
- SENDLVL (Send level)
Sets the signal level to be supplied to the REVERB effect. The setting range is 0 - 100. This setting is made separately for each pad and is independent of the overall drum kit send level setting ( p.56) made in effect mode.
To control effect intensity for each pad individually, it may be best to set the effect mode send level to 0 and adjust the SENDLVL parameter for the pads.
NOTE
If the KICKDRY parameter in the patch currently selected for the REVERB effect is ON, changing the send level of a pad to
which the kick drum sound is assigned pad 0 of pad bank 1/2) has no effect. To turn the KICKDRY parameter on and off, follow the steps described in the section "Editing effect patches".
KITNAME (Drum kit name)
Lets you change the name of the drum kit ( 53).

Using Effects (Effect Mode)
This section explains the effects that can be used with the drum kit/bass program.
About the effects
The RT-223 incorporates two types of effects. The COMP EQ effect allows you to directly shape the overall sound of the drum kit/bass program. The REVERB effect is mixed to the original sound of the drum kit/bass program. These two types of effect can be used simultaneously and can be switched individually on and off. The characteristics of each effect type are described below.
COMP EQ effect
The COMP EQ effect is inserted in the drum kit/ bass program signal output and comprises functions such as compressor and low-fi sound simulation.

REVERB effect
The REVERB effect of the RT-223 lets you adjust effect intensity by controlling the level of the signal sent from the drum kit and bass program to the effect. The signal processed by the REVERB effect is then added to the final stereo signal. For the drum kit, you can also set the send level individually for each instrument sound.

HINT
In effect mode, you adjust the overall send level of the drum kit/bass program. To adjust the send level for individual instruments of the drum kit, perform pad send level adjustment in kit mode ( p. 51).
About patches
The COMP EQ effect and REVERB effect comprise different effect types that determine the category of the effect and different effect parameters that determine the intensity and other aspects of the effect. By first selecting an effect type and then adjusting its parameters, you can achieve a wide variety of sound characteristics. The sum of these edited effect settings is called a patch. Storing and recalling patches makes it possible to instantly switch among different effect settings. The RT-223 allows you to use 40 patches each for the COMP EQ effect and REVERB effect.
Using the COMP EQ effect
This section describes how to use the COMP EQ effect.
- In pattern, song, or groove play mode, press the [COMP EQ] key several times, so that the key lights up.
The RT-223 switches to effect mode, and the COMP EQ effect becomes ON. The display changes as follows.

- Use the VALUE [+] /[-] keys to select the patch to use.

The new patch is called up immediately.
HINT
- When you select an empty patch, the indication "EMPTY" appears on the display. In this case, the sound does not change.
-
If a playable pattern or song is selected in pattern or song mode, pressing the PLAY [▶] key will start playback of the pattern or song. This lets you check the sound.
-
To temporarily bypass the COMP EQ effect, press the [COMP EQ] key so that the key goes out.
The COMP EQ effect is turned off, and the indication "BYPASS" is shown on the display. To turn the COMP EQ effect back on, press the [COMP EQ] key once more.
- When the COMP EQ effect patch has been selected, press the [EXIT] key.

The effect mode is terminated, and the RT-223 returns to the previous mode.
Using the REVERB effect
This section describes how to use the REVERB effect. For this effect, you first select the patch and then separately adjust the send level for the drum kit and bass program.
- In pattern, song, or groove play mode, press the [REVERB] key several times, so that the key lights up.
The RT-223 switches to effect mode, and the REVERB effect becomes ON. The display changes as follows.

Using the Metronome (Metronome Mode)
The RT-223 incorporates a metronome function that is ideal to provide a guide rhythm for practice. The metronome also lets you use mixed beat patterns, such as 2 + 3 or 3 + 4 beat combinations.
Beat types
The metronome of the RT-223 supports beats using quarter notes or eighth notes as denominator (unit note). The following numerators (number of beats) can be selected.
| Denominator (unit note) | Numerator (number of beats) |
| Quarter note | 1, 2, 3, 4, 2+3, 3+2, 3+3, 6, 3+4, 4+3 |
| Eighth note | 6/8, 7/8, 12/8 |
Within the beats using the quarter note denominator, there are five subtypes (C1, C2, C3, C4, C5) that differ in dynamics and count detail. For example, if a 4/4 beat is selected, the C1 - C5 variations are as follows.





NOTE
- Depending on the beat type, some dynamics combinations are not available.
- For beats using the eighth note denominator (6/8, 7/8, 12/8), the dynamics cannot be changed.
Mixed beat patterns
When using the metronome at a 5/4 beat, you can select 2 + 3 or 3 + 2 as a numerator.


In the same way, when using the metronome at a 7/4 beat, you can select 3 + 4 , or 4 + 3 , resulting in different ways of counting the measure.


To use the metronome function, proceed as follows.
1. In pattern, song, or groove play mode, press the [METRONOME] key.
The [METRONOME] key lights up, and the RT-223 goes into metronome mode. The display shows the metronome pattern name and pattern number.

Setting the MIDI receive channel for each track (MIDI)
Setting range: oFF, 1 - 16, AUt (bass track only) (Default: drum track = 10, bass track = 9)
This item sets the MIDI channel for each track. Available settings for the drum track are oFF (not received) and 1 - 16. Available settings for the bass track are oFF (not received), 1 - 16, and AUt. "AUt" is a special setting for playing GM compatible standard MIDI files. When the RT223 receives a program change message for GM bass sound, it automatically switches the bass track to that MIDI channel.
When the [FUNCTION] key is pressed followed by pad (·) (MIDI), the display for setting the drum track/bass track MIDI receive channel to on or off is shown. Hold down the [DRUM] key or [BASS] key (current setting for the track is shown on the display), and use the VALUE [+] /[-] keys to change the setting.
Displaying the remaining amount of memory (PATTERN)
Pressing the [FUNCTION] key followed by the [PATTERN] key brings up a percentage display of the remaining amount of memory. This display is for information only, it cannot be changed.
Other Functions
This section describes examples for combining the RT-223 with optional equipment and external components.
Using the jam function
The jam function lets you use the foot switch to play multiple patterns assigned to pads in song mode. This is convenient when you want to use your hands for playing an instrument, while still being able to start patterns and switch them at any desired point.
NOTE
The jam function is available only when the RT-223 is in song mode.
The following four pads can be directly controlled with the jam function: pad 0, pad 4, pad 8, and pad [().
When you press the foot switch while the RT-223 is stopped, the pattern of pad 0 begins playing.
With each subsequent push of the foot switch, patterns are switched between pad 4 and pad 8. If you hold down the foot switch during play, the pattern switches to pad [()] (see illustration 1 below).
By specifying the NEXT parameter ( p. 38) for the above pads, you can use other pattern combinations or stop play after a specific pattern.
For example, assume that INTRO is assigned to pad 0 and VERSE A to pad 2. When you set the NEXT parameter for pad 0 to "P02", pressing the foot switch will cause INTRO to play, followed by VERSE A (see illustration 2 below). Similarly, if FILL A is assigned to pad 4 and VERSE B to pad 6, setting the NEXT parameter for pad 4 to "F06" will cause FILL A to play from the next beat after pressing the foot switch, and then play can be switched to VERSE B (see illustration 3 below).

If the ENDING pattern is assigned to pad [()] and the NEXT parameter is set to "StP", pushing and holding the foot switch will cause the ENDING pattern to be played, and then play will stop.
HINT
For songs which have pre-assigned patterns (song numbers 0 - 9), the NEXT parameter is set as follows for the respective pads.
| Pad | NEXT parameter |
| 0 | P02 |
| 2 | P02 |
| 4 | F06 |
| 6 | P06 |
| 8 | F02 |
| [0] | STP |
- Connect the FS01 to the [FOOT SW] jack on the rear panel.
- Press the [SONG] key to switch the RT-223 to song mode.

- Press the [FUNCTION] key and then pad 8 (FOOT SW).

The indication "FOOT SW" appears briefly on the display, followed by the currently selected foot switch function.
In this condition, you can change the foot switch function setting.
- Press the [SONG] key.
The indication "JAM" appears on the display.

NOTE
When the jam function is assigned to the foot switch, and the RT-223 is in a mode other than song mode, the foot switch will control playback/stop of the pattern/song.
- Press the [FUNCTION] key.
The foot switch setting is completed. In this condition, you can use the jam function. - If required, set the NEXT parameter for each pad ( p. 38).
- Push the foot switch.
Playback of the pattern assigned to pad [()] starts. Each subsequent push of the foot switch then switches patterns according to the NEXT parameter setting. If you hold down the foot switch during play, the pattern of pad [()] plays. (If you have set the NEXT parameter of pad [()] to "Stp", pattern playback will stop after that.)
Synchronizing the RT-223 to external MIDI equipment
The RT-223 can receive MIDI clock signals for synchronized operation with a multi-track recorder, sequencer, rhythm machine, or similar equipment. This allows playback of the patterns or songs of the RT-223 with the tempo determined by the external equipment.
