I've got a playback problem with the new updated dsp distorsion unit : that seems to create lots of pops while calling some note-offs events.
Check the attached .xrns demo file to check it for yourself.
I've tested it under Windows 10 64bits :
under Renoise 3.0.1 32bits = works as expected
under Renoise 3.1.0b1 32bits = cracks/pops
