3.5 Panning/Balance
Panning (mono sources) or balance (stereo sources) can be set using either
absolute values or in relative increments/decrements.
MSB and LSB represent a parameter number showing where the signal is
being sent from and where it is being sent to.
MSB/LSB parameter numbers are shown in the
Absolute values are set with a combination of coarse and fine values. Ranging
from
00 00
(full left) to
7F 7F
(full right), with centre being
3F 7F

A relative pan/balance message uses the same parameter number, but with
an increment or decrement byte. Incrementing moves to the right and
decrementing moves to the left.
