LFO (Low Frequency Oscillator)

Each synth and FX track has its own LFO that can automatically modulate one parameter over time, adding movement and expression to your sounds.

Accessing LFO Settings

  1. Enter Track Mode (press Track)

  2. Select a track

  3. Navigate to page LFO settings page (3rd for synth tracks, 2nd for FX tracks)

LFO Parameters

Rate

Controls the speed of the LFO oscillation.

  • Lower values = slower modulation

  • Higher values = faster modulation

When using the Random shape (see below), the LFO Rate controls how fast the LFO switches from one random value to the other.

Amplitude

Controls how much the LFO affects the target parameter.

  • 0 = No effect

  • Higher values = More dramatic modulation

There are three modes that control the direction and range of modulation (Add, Bipolar, Sub). Press A to switch to the next mode, press B to switch to the previous mode.

Add (Positive)

Modulation adds to the target parameter value. The LFO output ranges from the base value upward.

LFO Add

Use this when you want the parameter to increase from its set value. For example, if filter cutoff is set to 50%, the LFO will sweep from 50% up toward 100%.

Bipolar (Center)

Modulation oscillates around the target parameter value, going both above and below.

LFO Add

Use this for classic vibrato and tremolo effects where the parameter swings symmetrically around its set value. For example, if pitch is set to a note, the LFO will create vibrato by going sharp and flat around that pitch.

Sub (Negative)

Modulation subtracts from the target parameter value. The LFO output ranges from the base value downward.

LFO Add

Use this when you want the parameter to decrease from its set value. For example, if filter cutoff is set to 80%, the LFO will sweep from 80% down toward 0%.

Shape

Selects the waveform shape used for modulation:

Shape

Description

Sine

Smooth, natural modulation

Triangle

Linear rise and fall

Ramp Up

Rising linear ramp

Ramp Down

Falling linear ramp

Expo Up

Rising exponential ramp

Expo Down

Falling exponential ramp

Random

Random values

Shape Modifiers

The Shape setting also includes two important modifiers indicated by small letters:

L - Loop

  • Enabled with button A

  • When enabled, the LFO continuously cycles

  • When disabled, the LFO runs once per note (like an envelope)

  • When disable and the Random shape is selected, a new

S - Sync

  • Enabled with button B

  • When enabled, the LFO resets every time a note is played

  • Useful for consistent modulation at note (like an envelope)

  • Combined with the Random shape and loop disabled, a new random value is generated only when a note is played providing a “sample and hold” effect.

Target

Selects which parameter the LFO modulates:

Target

Effect

P1

Modulates engine parameter 1

P2

Modulates engine parameter 2

P3

Modulates engine parameter 3

P4

Modulates engine parameter 4

Volume

Modulates track volume (tremolo)

Pan

Modulates stereo position (auto-pan)

LFO Modulation Visualization

On the LFO page, when a target is selected, an LFO visualization bar is displayed. A continuous line, starting from left of the screen, shows the current base value of the target parameter. On top of it, a dotted line shows the effect of the LFO on the target parameter.

The LFO can add to the base value (Add and Bipolar modes):

LFO visualization: Add to base value

The LFO can substract from the base value (Sub and Bipolar modes):

LFO visualization: Substract from base value

The LFO effect can push the parameter value to the minimum or maximum limits. In such cases an arrow is displayed either at the begining or the end of the bar.

LFO visualization: minimum limit
LFO visualization: maximum limit

This visualization can be used to understand and finely tune the LFO settings.

LFO Modes

By combining Sync and Loop settings, you can create different behaviors:

Sync

Loop

Behavior

Off

On

Free-running continuous LFO

On

On

LFO resets on each note, then loops

On

Off

Envelope mode - runs once per note

Off

Off

LFO is disabled at the end of the running cycle
