This is a shot of my main synth rig. CZ on top, Kawai K5-m underneith, Moog MG-1, then Ensoniq Mirage. Tucked away in the back is another Ensoniq Mirage and at the side is an old Yamaha RX-21 drum machine. It's a pretty crappy sounding drum machine but the nice thing about it is it is very, very, very vanilla which makes it great for putting effects on. On it's own it sounds like crud but with the right effects on it you can really get some far out sounds.
On top of the Mirage is a Casio PT-80. Not much of a synth but it has some really cool cheese-o-matic beats in it that makes it a useful thing to have around. On top of the Casio PT-80 is a MIDI Input Selector that I built myself. It lets me route the MIDI OUTs from 4 different pieces of gear to the MIDI IN on the Atari ST computer. Very handy when you don't like swapping cables and a hell of a lot cheaper than a MIDI Merge.
