LFO
A slow wave that modulates knobs on other modules
Open in the synth with a demo patch Open ModularWhat it does
An LFO is a low-frequency oscillator: the same wave as an ordinary oscillator, only very slow, from one cycle per 100 seconds up to 20 per second. You do not listen to it; you patch it into knobs (filter cutoff, pitch, volume) and the knob starts moving on its own. Sample & Hold gives random steps, Smooth random a random but gentle line, and Sync ties the period to bars instead of hertz.

Try this
- Patch LFO → filter Cutoff and set the cable amount to 0.3 so the tone breathes slowly.
- An LFO at 0.03 Hz (one cycle every half minute) on the cutoff is movement you do not notice at first, but without it the patch feels static.
- The Smooth random shape on a VCA Gain makes the volume feel alive, as if someone were quietly riding the fader.
