some have probably followed my problems with internal audio routing with Soundflower & JACK.
I need a very solid solution and I'm looking for on the hardware side.
RME Fireface UC seems the good compromise (even if the price is high)
Totalmix feature seems the way to audio route from an application to another by using the audio interface itself (loopback without real wire loopback of course)
Have you experiences with it and Max ?
