Tuckstir Anybody with linux experience here?
I used Linux for around 15 years. Only stopped when I switched to Mac.
I used Ardour as a DAW and it was fantastic. This was years ago and I never tried anything with MIDI.
JACK seemed to be temperamental. I know it was meant to be the answer to all of the audio issues on Linux but that was only true when it worked. Things have probably changed since then, though. In fact, I think I only finally got it all working when I tried Ubuntu Studio. So you should be fine.
(I went Storm Linux → Slackware → Debian → Ubuntu, with Ubuntu Studio for guitar → Mac.)
If memory serves, I tried Rakarrack and it was pretty good. I did this track with Ardour and, I think, Rakarrak for the effects, etc:
