LFO

The LFO page sets up the eight project LFOs: their shape, rate, depth, phase and polarity. The LFOs do nothing to the sound until the Mod Matrix routes them to a parameter. Routing is done on the companion Matrix panel.

Tap an LFO (1), then pick the setting to edit (2). The value pads set it.

Choosing an LFO and a setting

  • Step pads 81-88 select LFO 1-8. The selected LFO blinks. Each LFO pad brightness shows that LFO’s current value, so a bipolar LFO goes dark, bright, dark as it swings.
  • Step pads 71-75 pick what the value pads edit: Shape, Rate, Depth, Phase, and Knob channel.

Values

Setting Value pads Choices
Shape 41-47 Sine, triangle, saw up, saw down, square, sample and hold, smooth random
Rate 41-48, 31-35 13 rates, slowest first: 16 bars, 8, 4, 2, 1 bar, 1/2, 1/2 triplet, 1/4, 1/4 triplet, 1/8, 1/8 triplet, 1/16, 1/16 triplet
Depth 41-48, 31-38 16 steps from 0 to 100
Phase 41-48, 31-38 16 steps from 0 to 337 degrees, in steps of about 22.5
Knob channel 41-48, 31-38 MIDI channel 1-16 for the CT knobs. Tapping the channel already set returns it to the device preset (channel 3 on the Circuit Tracks)

Options (selected LFO)

Pad Option Default What it does
21 Unipolar or bipolar Bipolar Unipolar runs 0 to 1, bipolar runs -1 to 1
22 Retrigger On Restarts the LFO on transport start
23 New seed Seed = LFO number Gives sample and hold and smooth random a new sequence. Applies to those two shapes only
24 Knob control Off Lets the CT knobs edit the current page. A Global setting, shown here too. See Knob control
25 CT track follow Off Lets the Circuit Tracks track-select message change the TrackJammer track. A Global setting, shown here too

All LFOs start as sine, with a rate of one bar, depth 100, phase 0, bipolar and retrigger on.

Not yet verified on hardware

CT track follow (option 25) reads the Circuit Tracks track-select message. Whether its track index matches TrackJammer’s order has not been checked on hardware.

Notes

  • LFO edits are not in undo. Edits made in the Matrix panel are not undoable either.
  • The Matrix panel edits the same LFOs, and a change in either place shows in the other.
  • Knob control and motion recording are described in Knob control.
