LFO page and LFO types (M4)

holds one LFO per track in five types — duck, element, random, tremolo and value. changes the type; most types share one layout: source or speed, amount, destination page, parameter.

An LFO rides a knob for you. Choose what drives the movement — a repeating wave (value), random steps (random), the unit's motion, microphone or envelope (element), another track's rhythm (duck) — then aim it at an encoder on the track's pages. Tremolo skips the aiming: it is wired to pitch and volume.

Details

  • switches the LFO type between duck, element, random, tremolo and value.

    TE’s guide
  • Duck arrived in OS 1.1.0; the guide's sentence listing the LFO types still counts four and leaves it out.

    TE’s changelog
  • In element, random and value, E1 sets the source or speed, E2 the amount, E3 the destination page and E4 the parameter on that page; duck and tremolo use their own layouts.

    TE’s guide
  • The destination is one of the track's module pages and the parameter is one of that page's four encoders; E4 can be turned or clicked to choose it.

    TE’s guide
  • Extra settings sit behind encoder clicks or plus a turn; on some types a click on E1 changes the waveform shape.

    TE’s guide
  • Speed controls are tempo-synced over their anti-clockwise range; turned clockwise until a dial icon appears, they run at a free rate.

    TE’s guide
  • On screen a synced speed reads as a count beside a note value, 8 with a 32nd at the slow end, then 6 with a 16th, 4 with a quarter and 2 with a whole note as it turns; from the middle of its range a clock dial shows the free rate.

  • Synced, the speed doubles every eighth of the lane: in the middle of the synced range one cycle lasts a quarter note, anticlockwise an eighth, a 16th, a 32nd and a 64th, clockwise a half note and a bar.

  • Free, the LFO stands still at the dial's first position and speeds up ever faster, to about 21.5 cycles a second at the end.

  • Amount ladders are centred on zero (CC 64 over MIDI); either side of it sets the same depth with the modulation inverted.

  • Aimed at a filter's cutoff, value and random sweep its whole range at full amount; half the amount from a middle cutoff already reaches both ends.

  • The amount can go below zero to invert the modulation; OS 1.1.3 fixed how negative amounts are drawn.

    worked out
  • On drum tracks the LFO restarts with every new note.

    TE’s changelog
  • Over MIDI, CC40–43 on the track's channel drive the four encoders in order, in all five LFO types.

  • No MIDI CC is known for the LFO type.

    community
  • With the LFO off, the page is dimmed under an off box; pressing again switches the LFO on.
