[sdiy] Korg Poly61 a peculiar design!!

[Paul Burns]

Is the keyboard totally dead , or just partially ? They can be resurrected
with a bit of TLC...I have done so with a number and also rebuilt the
damaged traces from the nicad corrosion ...

Regards

Paul

Hi

I have a Poly61 too but with a dead keyboard. The keyboard is the true weak
point of this synth, and there is no MIDI(sic)

I had +/- in mind to design a special MIDI interface for it to emulate the
keyboard.

To rebuild /hack the cpu board seem to be a lot of work to do anyway , but
nothing impossible , just time consumming.

A programmer like my MCV32 ( or like) could probably do the job to manages
CVs
and extra panels pot. I have adapted this board to replace the CPU into many
RSF
PolyKobold who are much morecomplex devices  , so it should work on a Poly61
,
but this will not replace the keyboard anyway.

I am interested  by a readable schematic , at least to help me to decide
what
todo with this synth who is taking dust here since many years ...

Thanks,

Marc B.
