hello! I found a good site yesterday which has good synthesizer schematics (I'll give you the link if you want). I'm going to try and build a VCO, VCF, and VCA.
My problem is how to get pitch and gate signals. Obviously its the keyboard that does this, but how? What circuit do I need to make to recognise note presses and output CV signals? thanks.
Note: as the keyboard is a 1V/oct synthesizer, I'll need each successive 12 notes (i.e. an octave) to output one volt higher than the last. If one octave ranges up to a volt, then each key should output 0.083333..V .. I think
