White Crow offers 8 basic waveforms: saw, square, pulse, double-sine, saw-pulse, reso1, reso2 and reso3. A second set of (identical) waveforms can be added to create new unusual waveforms. Each of the two PD oscillators is made of 5 sub-oscillators that can be detuned for the creation of fat rich sounds. The phase distortion amount of each oscillator can be modulated by 2 ADSR envelopes, an LFO, and velocity. This will affect the sound timbre over time instead of the regular filter modulations. A lowpass filter can also be used as an additional sound shaping tool.
