My custom synthesizer work
1. Amplifier - LM13700 - matched-pair PNP exponential converter - CV of 10V -> Gain=1 - CV of Gain=\~0, 6 decades below Gain=1 - allow overdrive to Gain=2 - ideally this would begin to clip - mixdown - mono - full mix -> left and right - stereo split - A+C->left B+D->right - Direct stereo input jack - mix arbitrary signal with mixdown - e.g. for accepting signals from other synths 2. Oscillator - 0-10V, 1V/octave, A0 to A10 - Square/Triangle core via LM13700 - Waveshapper for triangle -> sine - PWM control - triangle wave applied to comparator with CV controlling reference. Triangle wave…
