I don't understand it totally. Let assume I have to midi tracks in qtractor
and I want to record those to two audio tracks in qtractor. But there is
only master_in1 and master_in2.

When I add an audio track, I can only choose for master_in. Also for new
audio track number two, master_in. How to route output of synth 1 to track1
and synth 2 to track 2?
