Hi Lugia,
Yeah I need to open a support ticket with KMM why Ableton cannot recognize the K-Mix via USB connection when it should. I will probably do that this week as time permits. I was troubleshooting different options to determine the weak link in the recording chain. At least for now I can dump audio from the modulars to my RME Babyface and record that way so all good in the short term. I tried a bunch of driver ASIO settings on Mac OS X and it would not recognize the mixer. It did recognize my RME Babyface and my A190 USB to MIDI CV module.
