Circuit Overview:
     16 voice Analog synth with 2 oscillators AND two filters/ voice, digital fx, arpeggiator/sequencer. I've never seen the docs but have played around with one. They are way cool. If anyone has a good link let me know.


Service Tips:
      Always verify power supply voltages if problem looks like it could remotely be power supply related. I have seen some bad solder problems and one intermittent processor reset problem that required a new board in an Alesis product. Not sure what's common if anything on these yet though.


Parts:
Advanced Musical Electronics has a lot of parts for Alesis stuff. THey only deal with techs though.
I've also seen All electronics carry displays occasionally at low prices. Alesis/Numark should have all the support for these but haven't dealt with them for a while.
