MIDI Mutes
Pressing any input or output channel MUTE switch
transmits a MIDI Note On message. Similarly,
receiving a MIDI Note On message will turn the
associated channel mute on or off, unless the
channel has been made automation safe.
Console mutes are mapped to MIDI Note numbers
as shown in the table. Running status is supported
on receive and transmit.
Transmit. Pressing a channel MUTE switch
transmits the following Note On messages:
9n cc vv 9n cc 00
Where n = console MIDI channel number
cc = input or output channel number
vv = 3FH for mute off, 7FH for mute on
Receive. The console responds to the following
MIDI Note On message:
9n cc vv (00 is ignored)
Where vv < 40 = mute off,
40 <= vv <= 7F = mute on
Snapshot Memories
Recalling a snapshot will transmit a MIDI Program
Change message. Receiving a Program Change
message will recall a snapshot.
Snapshot numbers 1 to 128 are mapped to MIDI
Program Change numbers 0 to 127. Running
status is supported on receive and transmit.
Transmit and Receive. The message format is:
Cn pp
Where n = console MIDI channel number
pp = console snapshot number 00 to 7F
MIDI AFL Messages
SysEx message strings are transmitted each time
an output channel AFL switch is selected or
released. These are for use with
BSS and dbx
speaker management systems to automatically
select the remote control surface associated with
the output being AFL monitored.
