1222: CV and 1v/oct is frequency control (CV is attenuated, 1v/oct isn’t). PWM is CV for pulse duty cycle. SYNC is a bit [complicated](https://lookmumnocomputer.discourse.group/t/as3340-vco-w-hard-soft-sync-fm-modulation/249/2); negative and positive edges reset the oscillator in various ways. FM is linear CV for frequency modulation.

The three outputs are various waveforms (square/pulse, sawtooth/ramp, and triangle).

Would have to go look at the panels/schematics for the others. Maybe later, if nobody beats me to it 🙂
