moog keyboard question (diy)

[Alex Stettler]

hello


I'm going to get an old keyboard today, to begin my constructions.

So there's still a question up:

As far as I know, the minimoog had a single switch keyboard controller.

So can anyone, say me or have an schematic, of a circuit, which makes my
keyboard I want to get, into a low-note priority keyboard?
I would be nice if I press to keys at the same time, I mustn't be afraid of
a strange tone between those keys, only the CV of the lowest pressed.

Does anyone have a schematic of the minimoog keyboard circuitry?


The end of this work, should be a "minimoog" but with the features I miss on
the original:
-Two separate LFOs, so you didn't have to use the 3rd VCO
-S/H stage on keyboard, so a full ADSR EG is possible, and not only the ADS
-Perhaps sine as a 7th waveform.


I like building and designing circuits and PCBs, and a old minimoog would
cost me too much, and I already got a hammond organ, so there's not so much
money left :-)
