When using the RD-300SX with an external MIDI sequencer, it is recommended to turn Local Control off to prevent double triggering or unintended playback. This setting disconnects the keyboard from the internal sound generator, allowing the sequencer to control the RD-300SX directly.
Use the following procedure to set the local control ON/OFF:
- Press the [EDIT] button.
The indicator lights, and the RD-300SX switches to Edit mode. - Press [INC] / [DEC] buttons to select “UtL (Utility)”, then press the [ENTER] button.
- Press the lit [GUITAR/BASS] button.
- Use the [INC] / [DEC] buttons to change the value.
- Press the [EDIT] button so it is not lit.
