Tremolo LFO (vibrato and tremolo)

The tremolo LFO is wired straight to pitch and volume — one depth for vibrato, one for tremolo — plus speed, a fade envelope and a waveform shape.

Tremolo is the quickest way to make a sound move: no routing, just two depths. A little vibrato at a moderate speed gives leads and strings a natural wobble, while the volume depth makes the classic throbbing tremolo. Use the envelope so the effect grows in after the note starts instead of arriving at once.

Details

  • Tremolo varies the track's pitch and volume directly, so it has no destination or parameter to choose.

    TE’s guide
  • sets the tremolo's waveform shape. TE's caption for that control repeats the random LFO's envelope text; its title and diagram point to shape.

    worked out
  • The tremolo page labels its fields rate, vib, vol and env, with a card labelled shape under env that shows the waveform (sine, square …); vib and vol are pointers on tick ladders.

  • While synced, rate shows a note-value icon with a multiplier (8, 6, 4, 2 …); turned further clockwise it becomes a clock dial whose hand turns, and the rate runs free.

  • Env is drawn as a line that rises at 0, lies flat at 64 and falls at 127.

  • The vol ladder dips the level to about a fifth at full; vib wobbles the pitch by about ±25 cents at a quarter, ±190 at half and more than an octave at full, growing ever faster.

  • Env at 64 keeps the tremolo steady; toward 0 it fades the tremolo in slowly, toward 127 it fades it out, at 127 at once.
