ok, i'm updated, went smoothly
stretching is working, though i need to manually set bpm to samples, instead of them autodetect it. it sounds ok, i guess, cause i'm gonna use it mostly on drumloops in live jam situation. bass stuff stretches not so well
midi master sync improved in my opinion, tried it with octatrack, sounds tight enough.
also tried ableton link sync with my iphone app, it syncs ok.
so far so good!
