What You Can Do with MIDI

You can use MIDI with the RC-50 for the following kinds of operations.
* Use of MIDI requires that the MIDI channels be matched with those of
the connected device. Data cannot be transmitted to, nor received from
another MIDI device unless the MIDI channels are set properly.

Outputting Tempo Data and Data for
Starting and Stopping Playback
• The RC-50's performance tempo data is transmitted to external
MIDI devices as MIDI clock.
Synchronizing tempos to the RC-50 enables control of MIDI
clock-based effects processors and other such devices.
• Playback start and stop operations with the RC-50's pedals can
be transmitted as MIDI Start and Stop messages.
Sequencers, recorders, and other such devices can be
synchronized to start and stop playback simultaneously with
the RC-50.

Outputting Program Change Messages

When a patch is selected with the RC-50, a Program Change message
corresponding to the selected patch number is transmitted
simultaneously. The external MIDI device switches its settings in
accordance with the received Program Change message.

Outputting Control Change Messages

An ongoing description of all operations you perform using an
externally connected foot switch or EXP pedal can be output in the
form of data called Control Change messages. These messages can
be used for various purposes, such as controlling the parameters of
an external MIDI device.

Controlling Operations from
External Devices
Receiving Tempo Data and Data for
Starting and Stopping Playback
• The RC-50 can receive MIDI clock from external MIDI devices
and perform at the same tempo as (be synchronized with) the
external MIDI device. This enables control of the RC-50 using
the same tempo as that of recorders and other equipment.
• Playback of the current phrase and control of All Stop can be
achieved through receipt of MIDI Start and Stop messages.
If Simul-Start (p. 50) is set, you can also start playback of any
desired phrase from an external MIDI device.

Switching Patch Numbers

The RC-50's patches switch simultaneously upon receipt of
corresponding Program Change messages from external MIDI devices.
The following figure shows a connection scheme whereby the
performance with the RC-50 is automatically played as a
backing performance. Patches switch automatically when a
Program Change message (Program Number) corresponding to
the patch, along with the performance data, is input at the point
where you want the RC-50's patches to be switched.

Receiving Control Change Messages

The RC-50 can be controlled using Control Change messages from
external MIDI devices.
You can set how the RC-50 responds to MIDI Control Change
#1, #7, and #80 with the CC#1/CC#7/CC#80 Func setting (p.
77).
You can also change the RC-50's tempo by connecting an
optional FC-200 MIDI foot controller.
