Selecting the Transmit Channel
(Tx Channel)
MIDI organizes things into “channels,” which are numbered
from 1 through 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.
Select the transmit channel (1–16) of the KR.
The channel setting is at “1” when the KR is powered up.
If the keyboard has been split into upper and lower sections,
messages from the left-hand section are fixed at “3.”
The KR receives messages on all channels from 1 through 16.

Disconnecting the Internal
Sound Generator and
Keyboard (Local Control)
When connecting a MIDI sequencer, set Local Control to
“OFF.” The setting is at “Local Control ON” when the KR is
powered up.
As illustrated, information describing what has been played
on the keyboard is passed to the sound module 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 disabled, by setting the unit to what is
known as “Local Off.”

When connecting a unit in the Roland MT series, you don’t
need to switch off Local Control. MT units transmit Local Off
messages when their power is switched on. First turn on the
power to the KR, then after a few moments, play a note on the
KR; when you turn on the power to the MT Series device,
Local Off is automatically enabled for the KR.
