[sdiy] The Mighty Korg KR-55

[Dj Sinistral]

Hi everybody!

I'm pretty new to this list, and I've got a challenge for some clever
circuit gurus!

The Korg KR-55, reportedly used by Jean Michelle Jarre and others, has
some great analog drum circuits, but no sound shaping controls like  
attack,
decay and tune.
So can it be done??

I've uploaded the schematics here: http://rafe.com.au/KR55schems/

The circuits look pretty basic with clearly separated sections for each
instrument. Controls for the kick, snare and hats would be plenty. I  
imagine
a few well placed pots will do it.

Thanks heaps!!!
