"Ableton Live 5.2, I'm using it more now than Cubase SX 3"
I am even getting my micro edits on in this mug, on drum edits, for drum and bass. I like not having to do as much work time stretching loops to fit my track tempos. The only thing I don't see ableton doing is tempo track, so you can change the tempo in the track itself, using automation, otherwise, I've been knocking out tracks left and right, drum and bass, hiphop and downtempo, etc. Peace.
