found it in (where else) a second hand store, but I knew it was good cause' the filter section afects the rhythms, tone,bass/chords and does a great job of just getting weird sounds. Sliders for the filter includes: attack, decay, sustain level,cut off, resonance. Has a great wah,wah effect with a slider for rate control also afecting the stereo chorus. Outs for external speakers (loud), vibrato. But after open it to clean it I started to mess with it and found several spots where I can put pots, switches, etc. to afect the sounds. there's even trimmers for the drum section to make them bigger sounding. It was fun to play with it for a while but now I need the space so if somebody wants it give me a call
Comments About the Sounds:
well, it's a casio but with the filter afecting anything you wish most sounds are ok after toying with the sliders.
