Discussion about the Korg PolySix synthesizer

Radek,

The attenuator works by sending data line DO3 back to the PIO bus on the
CPU. Check the switch, diodes and then all the connections back to the
KLM-367 involving DO3, P10-13. Study the schematic first though as this is
coming from memory, and mine ain¹t what it used to be!

Cheers,
Andy
