Connecting External MIDI Devices

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-300SX has the following two types of MIDI connector. Their
functions differ as described below.
fig.04-01
For instructions on connecting the external devices, refer to
"Connecting the RD-300SX to External Equipment" (p. 12).
MIDI IN Connector
Performance messages from an external MIDI device are received
here. These incoming messages may instruct the RD-300SX to play
sounds or switch tones.
MIDI OUT Connector
MIDI messages are transmitted from this connector to external MIDI
devices. The RD-300SX's MIDI OUT connector is used for sending
the performance data of the keyboard controller section as well as
data used for saving various settings and patterns (Bulk Dump
→p. 44).

Using the RD-300SX As a
Master Keyboard
By connecting an external MIDI device to the MIDI OUT connector
on the RD-300SX's rear panel, you can then control the external MIDI
device with the RD-300SX.
Normally, the RD-300SX transmits Note messages from the MIDI
OUT connector, but you can control not only Note messages, but a
variety of other external MIDI device settings as well.
Make the following settings if you do not want to have MIDI
messages transmitted.
1.
Hold down [SHIFT] and press [MIDI Tx].
2.
Press [INC] or [DEC] to switch the setting to ON or OFF.
* To enable transmission, set this to ON.
This button is disabled when Tx Mode is set to Mode 2.
Selecting Sounds on an External
MIDI Device
To switch the tones of an external MIDI device, enter the program
number and the MSB/LSB of the Bank Select message as numerical
values on the RD-300SX.
1.
Press [MIDI Tx].
2.
Referring to the following, press the TONE SELECT button
to which the parameter you want to change is assigned,
then select the parameter.

If the RD-300SX transmits a Program number or a Bank number
for which no Tone has been assigned, an alternate Tone may be
selected, or in some cases, there may be no sound played. If you
do not want to transmit the Program number or Bank Select, set
the MSB/LSB to "--- (OFF)."
