28.7 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.

28.8 OSC (Open Sound Control)

Besides simple MIDI notes, the Mackie Protocol and Control Change commands, TotalMix FX

can also be controlled by the Open Sound Control, OSC. For details on setup and usage see

chapter 25.8.3.

An OSC implementation chart can be downloaded from the RME website:

RME offers a free iPad template for the iOS app TouchOSC (by Hexler, available in the Apple

App-Store):

The RME forum hosts further information, more templates (iPhone…) and lots of useful user

feedback.
