Record in Ableton with Circuit Tracks and Model12..?

[kenjoswe]

Hi all,
I have a setup with Ableton, Circuit Tracks, Tascam Model12.
Model 12 is connected to Circuit Tracks via midi.
Both are connected to Ableton via USB.

Model 12 has audio on the SD-card and Circuit Tracks has the same music but in midi
Model 12 sends audio to Ableton and Circuit Tracks sends midi to Ableton.
This works great in playback. Everything is in sync.

But I can't record audio and midi at the same time it in Ableton.
If I set 'Start record on record' to off and press Play on Model 12 nothing happens.

How can solve this?
