After watching my YouTube video “u-he ACE Tutorial: Patch Cables 101”, I had a viewer ask “How can i modulate the pulse width of the osciliator?”, so I thought I’d do a quick answer here in text form. Click the image above to see a larger version of the synth. Annotation numbers in diagram match steps below.
For VCO1, LFO2 is already hard-wired to modulate pulse width. To get going follow these steps:
- Turn the Waveform1 knob clockwise to select pulse width
- Turn the lfo2 knob clockwise. You’ll hear Pulse Width Modulation right away
- Turn the sync knob to increase the speed of modulation
- Turn pw knob to set the PulseWidth
Play around with other lfo2 params to get more extreme results.
