Faders
When a fader is moved, the ES-4/100 and ES-8/100 sends the
following message:
Bnh 07h 0xxxxxxxx 27h 0y000000
n 0 to 7, corresponding to faders 1 thru 8
xxxxxxx Most significant 7 bits of fader position
y Least significant bit of fader position.
For example, Fader #2 moved to full scale (FFh), would yield:
B1h 07h 7Fh 27h 40h
Conversely, to command a fader to move to a specified position,
the same message format is used.
Sending the least significant bit is optional. For example, the
command s:
B3h 07h 39h
and
B3h 07h 39h 27h 00h
are interpreted identically.
