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 HP107 receives all channels 1–16.
* When using the HP107 in Dual mode (p. 29) or Split mode (p. 30), the
left hand of the performance is transmitted on Channel 5 in Dual mode
and in on Channel 3 in Split mode. These MIDI Transmit channel
settings are fixed and cannot be changed. When connecting an
external MIDI device while using Dual or Split modes, use channels
other than 3 and 5 for the MIDI device.
If you press
the Piano Resonance [String] button
in step 2
of “Making MIDI-related settings,” 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 HP107
→
MT series, Local Off will be set automatically.
