Sean demoed the beta version of 1.5 at Sweetwater's Gear Fest for me this past weekend - very cool! New features include Oberheim filters (!), turntable-style scratching, 16 tunings and some more that I can't recall at the moment (I think there were some new FX routings, if I recall correctly). I was most impressed with the 16 tunings mode; you can use either the 16 sequencer pads to program in a melody line or play one live on the lower pads. It was a lot easier than tweaking with the tuning knob! Not sure when it's supposed to drop for users, but it seemed to be pretty close to ready from what he showed me. I hope so!
