Chapter 6. Connecting External Devices
Connecting MIDI Devices
By connecting an external MIDI device and exchanging
performance data, you can control the performances on one
device from the other. For instance, you can output sound
from the other instrument or switch tones on the other
instrument.

What’s MIDI?
MIDI stands for Musical Instrument Digital Interface, an
international standard which allows performance information
to be communicated among electronic musical instruments and
computers.
The DP-970 provides MIDI connectors, which allow
performance data to be exchanged with external devices. When
these connectors are used to connect the DP-970 to external
devices, an even wider range of possibilities becomes available.

* Set Local Off if you have connected the DP-970 to a MIDI
sequencer. Refer to “Switching Local Control on and Off” (p.
47). Also set your MIDI sequencer to MIDI Thru mode (so
that messages received at MIDI IN will be re-transmitted
without change from MIDI OUT). For details, refer to the
owner’s manual of your MIDI sequencer.

and no sounds can be selected.
