Duophonic keyboard circuit

[Hallgeir Helland]

Hello,

Have anyone built one? I have built two of TomG's one-switch-per-key
keyboard circuit, and it works great. But I remember some while ago
it was mentioned that such a circuit could easily be modified to give
two CVs. I'd like to build one, but I honestly don't know quite how
to go about.... a schematic would be the best, I suppose.  :-)

Thanks,
Hallgeir
