Controls

  • Rate0.1 to 15 Hz — Speed of the sine LFO.
  • Depth0 to 20 ms — Delay sweep range, from 0.1 ms to 0.1 ms + Depth; more depth means wider pitch swing.
  • Mix0 to 100% — Blend between dry and modulated signal (100% for pure vibrato, lower for chorus-like detune).

Best uses

  • Vibrato on vocals and leads
  • Tape-style warble
  • Chorus-like detune at partial mix
  • Lo-fi wobble effects

Properties
