For me problems appear the way like some uninitialized variables in the code. Some problems listed here:
1) I often get audio engine initialization error:
creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit
control device hw:0
SSE2 detected
all 32 bit float mono audio port buffers in use!
cannot assign buffer for port
cannot deliver port registration request

cannot assign buffer for port
cannot deliver port registration request
Nothing changed but restart Qtractor --- oops, now it started ok.
2) Patch / instrument initialization code: Some problem here. Appears for me this way: Created 4 midi tracks, ok. Record on first track, ok. Attempt recording any track 2,3 or 4, result failure, recording runs but tracks stays blank. Select some patch & instrument (in my case Korg X5) for a track, record now, result ok. In this case first track recorded ok without selecting any patch, other tracks no way without selecting patch.
3) Import midi file: It doesn't care whatever mute / solo I select but creates a new track. May be related to 2) ?
4) Sure way to crash always my Qtractor: Cancel now import (Ctrl-Z) and start to record to one of existing four tracks, the moment you press start recording Qtractor will crash / exit.
