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.

29. DAW Mode

Users that work exclusively with their DAW software, and don’t want to use TotalMix FX for

additional routing tasks, need a way to be sure that TotalMix FX currently doesn’t change the

DAW’s routing. While Reset Mix can do so, those users would be better served with a very sim-

ple surface that offers the interface’s hardware controls (gain, phantom control, instrument…),

but guarantees a straight 1:1 routing for all playback channels, and has no hardware monitoring

of the input channels (which is then done by the DAW software).

For such cases TotalMix FX includes an alternative operating mode. It can be booted into the

so called DAW mode. This simplified interface is for anyone performing all monitoring and rout-

ing within the DAW. The DAW mode restarts TM FX into a light version with just two rows, no

playback row, and no mixing faders in the input row. Routing is 1:1 only. Just the hardware con-

trols (if existing) and hardware output levels are available.

To change the current mode go to the menu, Options, and click on Operational Mode. Choices

are Full Mode (default, mixer active, all routing options available), and Digital Audio Workstation

Mode (straight playback routing, no input mix).

Several useful, advanced features are still available in TotalMix FX in DAW mode:

¾ Talkback, External Input

¾ Phones definition and handling with Talkback

¾ Speaker A / B

¾ All FX (EQ, Dynamics, Echo, Reverb)

¾ Mute and Solo

¾ Cue / PFL
