- USB: Connect a USB cable from the RD-6's USB port to your computer for MIDI communication and firmware updates.
3.5 Trigger Outputs
The RD-6 features two TRIGGER OUT jacks (1/8-inch TS) that can send trigger pulses to control external modular synthesizers or other compatible equipment.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output. | Volume knob is low; cables are not connected correctly; external mixer/interface input is muted or low. | Increase the RD-6's VOLUME knob. Check all audio cable connections. Verify input levels on your mixer or audio interface. |
| RD-6 does not respond to MIDI. | Incorrect MIDI cable connection; MIDI channel mismatch; external device not sending MIDI clock/note data. | Ensure MIDI cables are connected correctly (OUT to IN, IN to OUT). Check MIDI channel settings on both the RD-6 and the external device. Verify the external device is sending the expected MIDI data. |
| Patterns are not playing back. | Unit is in WRITE mode; START/STOP button not pressed; external MIDI clock is not running. | Ensure the MODE knob is set to PLAY PATTERN. Press the START/STOP button. If syncing to external MIDI, ensure the external MIDI clock is active and sending data. |
