Phase Distortion Oscillator
The Phase Distortion Oscillator generates complex tones by modulating the playback phase of a waveform, producing filter-like timbral sweeps without a separate filter module.

| Freq Scale | Pitch input scaling: 1V/Octave or 1V/kHz |
At zero modulation depth, the output is a pure sine wave. Increasing modulation adds harmonics progressively. Modulate the depth with an ADSR envelope for time-varying timbres similar to a filter sweep.
The module is sensitive to sudden modulation changes — filter abrupt control signals to avoid clicks.
