I've been trying to setup Camtasia on the Mac.  I can record system audio (DAW)  but cannot work out recording a microphone through the Babyface pro.  You can select Babyface in Camtasia but it won't record it.  I am convinced it's totalmix (I've never liked totalmix years later I still find it to be a nightmare to understand.  I've had issue like this before with Totalmix I wish it wasn't so restricted - no other interface I've used makes it so difficult to just route audio.
