Synth Waveform Parameters

Has anyone mapped or tested the Playdate synth parameters for the built-in PO waveforms?

The SDK docs say square has one parameter for pulse width, and that kWavePOPhase, kWavePODigital, and kWavePOVosim each have two parameters that change “various aspects of the generator algorithm,” but I haven’t found details on what Param 1 and Param 2 actually control for each PO waveform.

I’m looking for either:

  • known meanings for Param 1 / Param 2 on POPhase, PODigital, and POVosim
  • listening-test notes about what each parameter seems to do
  • confirmation that sine, sawtooth, triangle, and noise ignore synth parameters

Context: I’m building an in-game music editor and want to label/hide parameters accurately instead of exposing generic “Param 1 / Param 2” controls.
