Digital Oscillator:
Osc 1: Pulse
Pitch: 0
Ctrl1: 100
Ctrl2: 3
This produces a triangle wave which crosses zero at just the right point to shave off the discontinuities which appear and disappear abuptly during sync
Osc 2: Pulse
Pitch: Higher than Osc 1, modulated by an envelope or LFO
Ctrl1: 50
Ctrl2: 0
This produces a square wave, though you can change it to a pulse or any other waveform.
Now set mix to 100% osc 2, sync and ring modulation on.
Now play
