Examples for sending MIDI strings*:
- Set input 1 to 0 dB: B0 66 40
- Set input 17 to maximum attenuation: B1 66 0
- Set playback 1 to maximum: B4 66 7F
- Set Output 16 to 0 dB: B8 75 40
*Note: Sending MIDI strings might require to use programmer's logic for the MIDI channel, start-
ing with 0 for channel 1 and ending with 15 for channel 16.
28.6 Loopback Detection
The Mackie Control protocol requires feedback of the received commands, back to the hard-
ware controller. So usually TotalMix will be set up with both a MIDI input and MIDI output. Un-
fortunately any small error in wiring and setup will cause a MIDI feedback loop here, which then
completely blocks the computer (the CPU).
To prevent the computer from freezing, TotalMix sends a special MIDI note every 0.5 seconds
to its MIDI output. As soon as it detects this special note at the input, the MIDI functionality is
disabled. After fixing the loopback, check
Enable MIDI Control
under Options to reactivate the
TotalMix MIDI.
