30.7 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.
