Geez, I love a good gearlist!

I use mainly:

Ableton Live 4, for the sequencing of midi and some loops
TR909 for drums, percussion and general weirdness when run thru
Sherman Filterbank
TB 303 for basslines
Juno 60 for pads, basslines, arpegs, fx, etc
Alesis FX (which I need to upgrade)

The flashing lights are incredible...
