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 specification 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.
About MIDI Connectors
The RD-300NX has the following two types of MIDI connector. Their functions differ as described below.
MIDI IN Connector
Performance messages from an external MIDI device are received here. These incoming messages may instruct the RD-300NX to play sounds or switch
tones.
MIDI OUT Connector
MIDI messages are transmitted from these connectors to external MIDI devices. The RD-300NX’s MIDI OUT connectors are used for sending the
performance data of the controller section.
