Discussion about the Korg PolySix synthesizer

Thanks for the suggestions once again!

I've replaced IC 30 and 31 with 7408, but will buy some 74LS08 and try
those.

Meanwhile, I'm down to my last few problems:

*Sub OSC does not work at all (aka is always off)

*Octacve 16' and 4' are both the same. (which is actually 16')

*Cannot write to memory. The LEDs look like things are going okay, but
then when you try to recall the last saved program, it is blank.

*Bank 2 and Program 2 LED's are always on still

*When you call a program, they are either blank, or the same one patch

I suspect that the 7408's might need replacing again, but that there
is something going on with IC29, or somewhere else along the chain
that included the subosc and octave.

PS - I got an original paper service and users manual in great
condition. I will make PDF copies of both and post link when they are
online, if that is not in violation of a rule here.

Cheers,
Sean
