This Ableton Learn Live segment walks through Vibrato mode in the Chorus-Ensemble device, covering how pitch modulation, LFO offset, and waveform shape each affect the character of a sound. Unlike Classic and Ensemble modes, Vibrato disables Feedback and Dry/Wet, so the effect is pure pitch modulation with no blending.
Rate and amount work together to set the feel: a fast rate with a low amount adds a subtle, human-sounding wobble to vocals or leads, while pushing the amount higher gives a more obvious, expressive vibrato.
The offset control splits the LFO between left and right channels, pushing them out of phase with each other up to 180 degrees for a full stereo spread. This is the same spatial widening principle used in the other modes, applied here to pitch modulation.
Switching the LFO shape from sine to triangle changes the motion from smooth and rounded to sharp and angular. The triangle wave snaps between peaks instead of gliding, making the vibrato feel edgier and more mechanical.
