With just a single square waveform and using the PW morph mode modulated with LFO2 I'm getting typical PWM.Icarus is completely based on wavetables and has no analog like PWM imlemention so the wavetables based on PWM (like e.g. those i created from the Slim Phatty and BS II) could be quite helpful and nice for this. BTW the INIT feataure in the wavetable editor alraedy allows to create a basic PWm wavetable (by clicking on INIT and then "Create wavetable PWM").
The nice thing with sweeping the oscillator on hardware synths with continuously variable oscillator is that the resultant wavetables have PWM baked right into them. Just like with the hardware synth - the wave knob in icarus works the same as the waveform knob on the synth. modulate either and it's instant PWM time.
