I use mine as a glorified external midi sequencer, slaved to the clock signal from the TR909

So I write drum parts and stuff with the 909 sequencer, and have Live trigger chords and leads in the external sound modules. Because Live is only sending midi data and has no audio or vsts in it, it works like a charm and uses minimal cpu

Another cool thing from this method is that I can load percussion / bass / fx into my sampler and trigger this from the 909...when the pattern sounds cool, i dump the midi into Live and have it play the sampler back - this lets me do detailed velocity & automation which the 909 can't do, plus it frees up the 909 sequencer to write a new pattern with.

The other good thing is that it means you sequence with Live in tandem with the 909, which only has a two digit display...so it gives you much more of a visual reference (could be considered a bad thing tho' too, depends how old school you are!)

It's taken me ages to work out how to fuse hardware and software into some kinda workable harmony...but this feels like the best workflow so far
