I have two keyboards, both capable of transmitting polyphonic (key) aftertouch, which I am looking to sell:
1) GeneralMusic GEM S2 Turbo: 61 note synth-weighted keyboard in excellent condition, includes pedal, all original manuals and software, AND the original box. This keyboard has SEVEN assignable sliders which work well with the CS-80V software. I will include a disc with a "CS-80V" Performance all programmed and set to go. I am asking $300 plus shipping (North America only, please).
2) Kurzweil MidiBoard: 88 note piano-weighted keyboard in fair/good cosmetic condtion (endcaps missing some paint but otherwise intact, a few scratches and dings- this unit was gigged), but works perfectly. Has the latest OS rev. 3.0, includes xeroxed manual. I am asking $450 plus shipping (again, NA only).
Poly AT was a major feature of the Yamaha CS-80, and it is pretty essential for emulation of the original. I had been using the GEM the past few months while looking for a MidiBoard, and then ended up with two (long story, ask me privately)! I am only looking to get back what I paid for them, prior to sending them back to eBay. If you are interested, please contact me via email (on AOL), I will be happy to send pics. On eBay I am "Marzzz" if you wish to check my feedback, I can also provided references.
