Channel Mutes
Pressing any console mute switch transmits a MIDI Note On
message unless MIDI has been disabled. Similarly receiving the
correct Note On message will control the channel mute unless it
has been made 'mute safe' or MIDI disabled.
Console mutes are mapped to MIDI Note numbers as shown.
Running status is supported on receive and transmit.
TRANSMIT - Pressing a console mute transmits the following
Note On message:
9n cc vv cc 00
where n = console MIDI channel number
cc = console 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)
Mute Patches
Recalling a patch will transmit a MIDI Program Change message
unless the MIDI is disabled. Similarly receiving the correct
Program Change message will recall a console patch unless
MIDI is disabled.
Console patches are directly 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 patch number 0-127
MIDI Dump Format
The format for Dump In and Dump Out is identical. The Dump is
made up of 128 System Exclusive messages (or packets) which
contain the contents of the console memory.
TRANSMIT and RECEIVE - The format for a single packet is
as follows :
F0 <sysex header> <packet no.> <data> <checksum> F7
<sysex header> = 00 00 1A 50 06 VV vv nn
VV = major software version number e.g. V1.23
vv = minor software version number e.g. V1.23
nn = console MIDI channel number
<packet no.> = packet number from 0 to 127
<data> = 7 bit block of console data followed by a
number of 00 pad bytes.
<checksum> = checksum to allow error detection.
KEY
M = Monitor path mute.
C = Channel path mute.
ST = Stereo input mute.
AX = Aux send master mute.
