hey karl. nice idea, but no matter how i set up sustain or loop nodes and regions, nothing produces the expected results. what i was thinking is that it would work like the envelopes in absynth and zebra. oh well, guess i'll just use them instead.
EDIT - aw dammit karl, i keep forgetting that a sync of 1 in rapture is NOT a whole note, it's a beat so an 1/8 sync is really a 1/32nd note and a 4 is a measure. duh. some of the envelopes are syncing now, some refuse downright to do it. my bad.
