New toy - Oberheim Systemizer

I'm thrilled to have found this on eBay for under £30 - an Oberheim Systemizer. One of the Perf/X series, it's a MIDI performance processor which adds zoning, velocity switch, controller switch, position cross-fade, velocity cross-fade, aftertouch cross-fade, controller cross-fade, local hold, split release, patch change and so on to your keyboard setup. I'll probably never need it, but since I have an Oberheim Cyclone, Strummer and Drummer, it's nice to have - lovely condition too, boxed with manual. Now I discover there's another Perf/X device, the Navigator, so I'll have to start looking for one of them...
