Im interested in learning about active waveshaping and adjustable wave generation circuits, including VCF's and VCA's for the purpose of building an analog synth.
Ive studied all of the basic opamp circuits including integrators, differentiators. Iv also studied the wein bridge , phase shift, and squarewave oscillators, comparators with hysteresis, clipping circuits, dc restoration, peak detectors, active rectifiers, opamp based Pulsewidth modulation circuits, ICL8038, ramp generator , LM566 & LM331.
So Now I need take the next step.
Circuits like the analog part of this schematic is what Im interested in, also LFO,s. I have a pretty good understanding of the previous linked circuit but Im still interested in learning more about the aforementioned type of circuits, so any tutorials or books( Id rather online tutorials though, as I dont have the $$ for...) would be very usefull.
Regards,
jmur
