Using the RD-300NX as a Master Keyboard
You can control the external MIDI device from the RD-300NX.
Normally, the RD-300NX will transmit note messages from the MIDI OUT connector, but if you press the [MIDI] button so the “MIDI” indicator is lit, you’ll
be able to control various settings on your external MIDI device in addition to transmitting note messages.
You can control internal and external sound generators independently.
If you press the [MIDI] button so the “MIDI” indicator is lit, the RD-300NX will be in a state where it can control an external MIDI sound module
(EXTERNAL layer). You push the [MIDI] button to switch between control of the Layer and control of the EXTERNAL layer.
You can also make detailed settings for MIDI messages transmitted to external sound modules.
What’s MIDI?
MIDI (Musical Instrument Digital Interface) is a standard specifi cation that allows musical data to be exchanged between electronic musical
instruments and computers. By using a MIDI cable to connect devices that have MIDI connectors, you can create an ensemble in which a single MIDI
keyboard can play multiple instruments, or change settings automatically as the song progresses.
