DSP-cheap continuous tri-square-saw/ramp morphing oscillator

[Tim Kleinert]

As the title says, a dirt cheap oscillator building block that allows continuous morphing between triangle, square and sawtooth/ramp waveforms. I discovered it by accident and thought it was rather neat. It uses less than half the amount of DSP compared a ShapeA oscillator.

Two parameters control the circuit: The bipolar SQR<>SAW control input provides continuous morphing between sawtooth, square (50/50 duty cycle) and ramp (negative sawtooth). The unipolar S/S<>TRI control input then provdes continuous morphing between this waveform and pure triangle.
