Is use a combination of several hardware synthesizers and a couple of samplers.
I could say I use anything except a computers. I HATE computers to make music.
Akai AX 60 and AX 80 for making analog rough sounds. Pads and some synth leads are done with the AKAIS
Roland MC 909 to make rythmical loops, and groovy samples.
Yamaha SY 99 to make FM sounds, weird panning effects, some effect noises
Roland SP 808ex to sample while playing. SP808ex has 1 hour of sample capability, so I use it to samnple while I'm playing. Loop sampling is done with the SP808. I also add COSM effects to the samples, and I record a lot from TV, radio, and microphone. Any kind of stuff.
Roland JUNO 106> I use it for basses, and sometimes, I play a couple of noises from it. Basses of the Roland JUNO are the best.
EMU command stations: they are used for a lot of drums. Percussions, like tambourines, cowbells and some congas come from
the EMU XL7 and MP7.
ROland JP8080: I use to create advance, weird techno sounds. Some leads,, basslines, and speciallly the kick comes from the JP 8080. I also process sounds from other synths thru the JP 8080 inputs.
Sometimes, I connect all the synthesizers with MIDI, using as the MASTER synth the command station, to syncronize all the equipment. Start to jam, and sample everything with the SP 808...
