Rui,
   I somehow missed this announcement the first time it came out or
didn't pay enough attention. So you've managed to get pitch shifting
into a Linux-based loop player?!?! Exciting. I've been waiting for
this since 1999! I'll have to give qtractor a serious look?

   The power of the commercial progs like Acid Pro, Ableton, FL, etc.,
is that I can drop in loops and they are automatically set to the
tempo of the session. Does qtractor do this? If I have loops recorded
at 136BPM and I'm doing a 119BPM session is the default pitch as
recorded and the default tempo 119?

Thanks,
Mark
