Channel Mode Messages - Yamaha S90 Owner's Manual

RPN (Registered Parameter Number) LSB
(Control #100)
RPN (Registered Parameter Number) MSB
(Control #101)
Messages which offset, or add or subtract values from a
Part's pitch bend sensitivity, tuning, or other parameter
settings.
First send the RPN MSB and RPN LSB to specify the
parameter which is to be controlled. Then use Data
Increment/Decrement (page 120) to set the value of the
specified parameter.
Note that once the RPN has been set for a channel,
subsequent data entry will be recognized as the same
RPN's value change. Therefore after you use the RPN,
you should set a Null (7FH, 7FH) value to avoid an
unexpected result.
The following RPN numbers can be received.
RPN MSB RPN LSB PARAMETER
00 00 Pitch Bend Sensitivity
00 01 Fine Tune
00 02 Coarse Tune
7F 7F Null
