Schematics / Richard Brewsters Version Of CGS-ASMVCO
Richard Brewster's version of CGS/ASM VCO ,from the notes on his website : It all goes back to 1976 when Bernie Hutchins published the schematics for the ENS-76 VCO Option #1.If you are into the design of circuits, I highly recommend getting hold of your own hard copy of Electronotes. The issues from the 1970?s are the best, including the Musical Engineer’s Handbook.You can study all four different schematics: Electronotes, ASM-1, Ken Stone’s, and mine, which is built on Ken’s PC board.
Specifications : Coarse and Fine tuning pots 1V/OCT CV input FM Input with attenuator pot, switchable between EXPONENTIAL and LINEAR resonse LINEAR FM can be AC or DC coupled Hard Sync input Pulse Width Modulation iInput Sawtooth and Pulse wave outputs, both +/-5V
