Hello, it is us again, the newbies building an analog synth for a school assignment.
We have some other questions demanding a solution:
We need some schematics for individual VCO, VCA, VCF, LFO etc. so we can maybe build those parts ourselves.
So if you know some useful url's or have some stuff on your HardDisk, pleas let ut know

greetings

Da Peter & Egbert Dudezzz.
