MIDI parameters
Backing Keyboard BK-5

Rx Octave
Use this parameter to transpose the notes received
on the selected MIDI channel (“Ch”) in steps of one
octave.
Rx Global Limit Low/High
These parameters allow you to set the note range to
be received. If not all note messages of the selected
MIDI channel should be received by the NTA “part”,
set the range to the desired values.
NOTE
The “Limit Low” value cannot be higher than the “Limit
High” value (and vice versa).
Parameters
The following parameters are located on the display
page that can be selected using [MENU] button‰
“MIDI” ‰ “Edit System” ‰ “Parameters”.
This page contains several parameters that are not
related to one another (the other MIDI pages always
concentrate on one aspect).
Part Switch
This parameter allows you to specify whether or not a
muted part should go on sending MIDI messages:
Internal: A muted part can no longer be played via
the BK-5’s keyboard or Arranger/song player but con-
tinues to send MIDI messages. Selecting “Internal”
and muting a part thus has the same effect as select-
ing “Local Off” (see p. 103).
Int+MIDI: A muted part can no longer be played via
the BK-5’s keyboard or Arranger/song player and no
longer sends MIDI messages.
Tx Velocity
Your BK-5 is equipped with a velocity-sensitive key-
board and a tone generator capable of responding to
velocity messages. Use this parameter to switch the
transmission (TX) of velocity messages on or off.
If you don’t select “On”, specify which velocity value
to use instead of the continuous flux. The value you
set will be used for all notes sent to MIDI OUT/USB
COMPUTER.
Tx SysEx
Use this parameter to specify whether (“On”) or not
(“Off”) the BK-5 should send SysEx messages. Such
messages are not standardized, so that each manu-
facturer can use them ad lib for temporary (or per-
manent) changes to the way a part behaves. Effects
parameters, for instance, can only be changed via
SysEx messages.
Such messages may slow down playback on external
MIDI instruments or yield no effect at all, which is
why you have the option to switch off their trans-
mission in the first place.
Tx Data Change
This parameter allows you to specify how the original
program changes of the songs you play back are
transmitted via MIDI. The BK-5 may change sound
addresses (usually CC00 and CC32 values) so as to
play back all songs with the best possible quality. If
you switch this parameter on, such real-time trans-
formations are also transmitted via MIDI. If you
switch this parameter off, the original sound
addresses are transmitted to the receiving device.
(But the BK-5’s tone generator continues to
“enhance” the songs you play back.)
Octave Tx
The “Octave Tx” parameter can be set to Absolute or
Relative . You may have noticed that if you assign a
bass sound to the UP1 or UP2 part in SPLIT mode, the
notes are transposed to allow you to play meaningful
bass lines using the UP1/2 part. “Relative” means that
this internal (and automatic) transposition is trans-
lated into MIDI note numbers.
In “Absolute” mode, however, the MIDI note numbers
sent to other instruments will be the ones of the keys
you actually press.
Rx Velocity
Your BK-5 is equipped with a velocity-sensitive key-
board and a tone generator capable of responding to
velocity messages. This parameter allows you to
switch the reception (RX) of velocity messages on or
