[sdiy] Yamaha CS-60 issues

[Roman]

Plus of course the glissando adder, so this rules out discrete logic design, and here comes small microcontroller.

It selects octave voltages from  one external resistor ladder and semitone voltages from another resistor  ladder and drives 8 outputs sequentially with Hz/V voltages, all  controlled by key assigner.   If it goes for $2000 (I saw them on ebay for $600) it's hard to believe  noone has ever done a replacement yet.   So, who's going to be first offering YM26700 retrofit?  Don't look at me, I don't have time for this.

What does the YM26700 do, and how easily do you think it could be cloned or emulated?   ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org
