Hi Louigi,

Currently luppp's sync is like this:
-resampling to achieve loop lenghts that correspond with "bars" in music
terms.
-BPM is currently set to a value, but dynamically modifyable trough MIDI (&
GUI soon)
-Resampling means that the pitch of loops will go up / down depending on
playback speed

I've fixed the pitch issue using the SoundTouch library, however it
glitched & popped quite
a bit too much. Either a better implementation using SoundTouch, or else
I'm going to use
libRubberBand, which seems to be the more widely used timestretch library.

Due to the resample to "bars" code, if you record some material, but not to
precise bars lengths
it will be resampled (just a little bit) but will sound aweful in the
harmonic sense :(

See the following issue: https://github.com/harryhaaren/Luppp/issues/2

Cheers, -Harry
