Type: nodetool.audio.synth.LFO
Namespace: nodetool.audio.synth
Description
Low-frequency oscillator emitting a control-voltage stream. cv, synthesis, lfo, modulation, modular
Output is offset + depth * wave(phase). With a clock patched, emits one chunk per clock chunk (sample-aligned) and resets phase on each clock rising edge; otherwise free-runs wall-clock paced until the run is stopped.
Use cases:
- Vibrato/tremolo via Oscillator fm or VCA cv
- Filter sweeps via VCF cutoff_cv
- Slow parameter drift in generative patches
