Using the RD-700SX As a Master
Keyboard
By connecting an external MIDI device to the MIDI OUT connector on the RD-
700SX’s rear panel, you can then control the external MIDI device with the RD-700SX.
Normally, the RD-700SX transmits Note messages from the MIDI OUT connector,
but when [EXTERNAL/INTERNAL] is on, you can control not only Note messages,
but a variety of other external MIDI device settings as well.
You can control internal and external sound generators independently.
Pressing [EXTERNAL/INTERNAL] so the button’s indicator is lit enables the RD-
700SX to control external MIDI sound modules. You use the [EXTERNAL/
INTERNAL] to switch between control of the INTERNAL zone and control of the
EXTERNAL zone.
You can also make detailed settings for MIDI messages transmitted to external
sound modules.
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.
The RD-700SX has the following three types of MIDI connector. Their functions
differ as described below.
fig.Q3-01
MIDI IN Connector
Performance messages from an external MIDI device are received here. These
incoming messages may instruct the RD-700SX to play sounds or switch tones.
MIDI OUT Connector
MIDI messages are transmitted from this connector to external MIDI devices. The
RD-700SX’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. 99).
MIDI THRU Connector
MIDI messages received at MIDI IN connectors are re-transmitted without change
from this connector to an external MIDI device. Use this in situations such as when
you use multiple MIDI devices simultaneously.
