ALLEN & HEATH SQ-6

 11
MIDI Protocol – ISSUE 1
3.3 Mutes
The SQ sends and receives absolute On or Off mute messages. It will also
toggle the mute state when either an increment or decrement message is
received.
MSB and LSB are a parameter number for the channel you wish to mute or
unmute.
 MSB/LSB parameter numbers are shown in the reference tables section.
The last byte of the full message then represents a mute on or off.

does.
