Topic: No sound - Loopback in Logic Pro with Babyface pro FS

Hi, Mac user here.

My loopback in TotalMix is set to ADAT 3/4 (signal activity working fine)
whenever I open an audio Track in logic (record enable button activated) I get no sound/signal activity.
The input of the audio track is set to In 3-4, the output is stereo out.

Any clues of what's wrong?

Re: No sound - Loopback in Logic Pro with Babyface pro FS

did you check other channel numbers ?
May be it arrives on input channels 5/6 in Logic ?

Nothing wrong, it’s how it should be: ADAT 3/4 are overall input channels 7/8, so all fine.
Analog 1-4 = channels 1-4
AS 1/2 = channels 5/6
ADAT 3-8 = channels 7-12
(Reverb/echo send/return = channels 13/14)

Good to know: in Logic you can set the input and output labels to the ones reported by the RME driver instead of 'channel 1-14'. In menu 'Mix' > 'I/O labels' (or similar, I have my computer in German so I don't know how exactly it would be displayed in English). You have to open a project first to do that (I don't understand why). These are the same labels as shown in Audio-Midi-Setup app.
