Roland RD-150 - MIDI Connectivity and Control

20
If you do not intend to connect a MIDI instrument to
the RD-150, you do not need to read this chapter.
MIDI stands for Musical Instrument Digital Interface,
an international standard which allows performance
information to be communicated among electronic
musical instruments and computers.
Connecting MIDI devices
The RD-150 features two MIDI connectors for trans-
mitting and receiving performance messages to and
from an external device. By connecting external
devices to these sockets, you can expand the possibili-
ties of your RD-150.

Out in
The RD-150 has two MIDI sockets: MIDI OUT and
MIDI IN. By connecting the piano to an external
MIDI device to these sockets, they can control each
other. For instance, you can play an external device or
change sounds on the external device from the
RD- 150.
MIDI OUT— This sends out messages describing
actions (such as playing the keyboard) to the MIDI IN
jack on the external device.
MIDI IN— This receives the MIDI messages sent by
an external MIDI device. The receiving MIDI device
will act according to the MIDI messages received, and
play notes, change Tones, etc.
Connecting a MIDI device
1. Switch off the RD-150.
2. Connect the MIDI jack (e.g.“OUT”) of the external
device to the opposite connector of the RD-150 (e.g.
“IN”) using an optional MSC-15/25/50 MIDI cable.

7.1 MIDI transmit/receive
channels
MIDI provides 16 channels. MIDI messages are com-
municated between two devices over a MIDI channel.
Even if the two devices are connected properly with a
MIDI cable, messages cannot be sent or received if the
MIDI channels are not set correctly. The RD-150
allows you to set two MIDI channels; one for the
Upper Tone, and a second for the Lower Tone. The
Lower Tone channel is used in Layer and Split modes
(see page 12). In Whole mode (when neither the
Layer, nor the Split mode is active), only the Upper
Tone channel is used.
Note: The MIDI channels you set are retained until the
RD-150 is switched off.
