Subject: Re: [korgpolyex] Repairing an EX-800

Uhu! Got it working!!!!!!!!!!!!! :oD

Totally bypassed the internal power supply. The schematic is a mess and
I didn't want to spend an entire night trying to calculate values for the
parts.

The poly works with +5, -5, +9 volts. The +9 goes to the analog output.
Put a PC power supply and it is working.

I'll write a tutorial up of how to do that, and identifying some
tensions on the schematic. Mike, I'd be glad if you put it on your site.

Now I have an EX-800 :) Only one button is broken (start/stop sequencer)
but I think I gotta many things to foul up here heheheheh
