"Make Phase-Distorted Wave" node

This article says:

In Casio's PD synthesis, the phase part of the oscillator […] is distorted in eight different ways (corresponding to the eight wave shapes on the synth) and the amount of distortion is controllable via a parameter called DCW (Digitally Controlled Wave-Shaping). When the DCW is at zero, you just hear a sine wave sound, but as you increase the DCW, the sine wave can be warped into a square or sawtooth (or one of the other eight CZ wave shapes).

…so I think, to do PD synthesis, instead of inputting VuoAudioSamples, you'd want to input a new nonlinear shape for the phase curve (to replace Make Audio Wave's sawtooth phase curve)?

Perhaps either a menu of a few preset curves, or a VuoList_VuoReal of points describing the curve to repeat every cycle. And, add an input port equivalent of Casio's DCW, to blend between linear phase and the selected nonlinear phase curve.
