yeah I think that's about it. They used to run all the streams/loops from AKAI S5000 or 6000 samplers live, triggered by MPC's, but they switched to using direct 24 bit 48 Khz audio from the computers.
There's a Nord Lead in the livesetup, and two Quasimidi technox modules and of course a Roland TR 909. No TB303 in the live setup, but you can hear 303's being used on some of UW's early records.
There's a good article about the technicalities of the liveshow
