Recently installed qtractor 0.6.0 from source, and everything was going swimmingly - until I went to look for all the .midi and .wav files I had been exporting - they had disappeared! I have successfully repeated the issue - go into any project, export several sliced up clips. They all appear in the file browser and are playable in Audacious. Then I close qtractor, and they all disappear! This technique worked fine in 0.5...
I'm entirely open to the possibility of this being an issue with my installation, rather than the program as a whole.
Any help with this would be great, I just lost a couple of hours work unfortunately :(
