Chapter 6. Connecting External Devices
■
MIDI Send Channel Settings
MIDI features sixteen MIDI channels, numbered 1–16.
Simply connecting a cable is not enough for communication
to take place. The connected devices must be set to use the
same MIDI channels. Otherwise, no sound will be produced,
and no sounds can be selected.
* The MP-70 receives all channels 1–16.
* If you are using Dual play (p. 19) or Split play (p. 20) on the MP-70,
only the channel you specify here will be transmitted.
If you press
the [STRINGS] button
in step 2 of “Making
MIDI-related Settings” (p. 38), a display like the following
will appear.

Switching Local Control on and
Off
When connecting a MIDI sequencer, set Local Control to
“Off.”
As illustrated, information describing what has been played
on the keyboard is passed to the internal sound generator
over two different routes, (1) and (2). As a result, you hear
overlapping or intermittent sounds. To prevent this from
happening, route (1) must be severed, by setting the unit to
what is known as “Local Off.”

Local Control ON: The keyboard and the internal sound
generator are in a linked state.
fig.localon.e
Local Control OFF: The keyboard and the internal sound
generator are in an unlinked state. No sound will be
produced by the keyboard when it is played.

* When a Roland MT series instrument is connected, it is not necessary
to make the Local Off setting. MT units transmit Local Off messages
when their power is switched on. If you turn on the power in the order
of the MP-70
→
MT series, Local Off will be set automatically.
If you press
the [VARIATION] button
in step 2 of “Making
MIDI-related Settings” (p. 38), a display like the following
will appear.

If you want to transmit a performance recorded on the MP-70
to an external MIDI device or computer, turn this setting
“On.” If this is “Off,” the data will not be transmitted.

related Settings” (p. 38), display like the following will
appear.
