Discussion about the Korg PolySix synthesizer

Der,

I had read about the bugs with the missing tracks... I guess I forgot to implement them... as well as the stock transistors in the wrong orientation. Still at work and won't be able to dig at it until later.

One more q about the 366B. What could possible me the most common culprit in causing the keyboard to stop functioning all together? Would it be the key assigner DAC circuitry? I once had an issue with a SCI Sixtrak that had a bad keyboard scanner that made it act really crazy with whacky tuning stability, but it still output a sound when I pushed down keys. I will look into this and the supply voltages when I get home tonight.

Thanks again for everyone's help and comments.
