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¶

Enter Track Mode (press Track)
Select a track
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

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:

Mode	Direction	Use Case
Add	Base → Max	Filter opening, pitch bend up
Bipolar	Min <-> Max (around base)	Vibrato, tremolo, classic modulation
Sub	Base → Min	Filter closing, ducking effects

Add(Positive)¶

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

Parameter
Value
  ^
  |     /\      /\
  |    /  \    /  \
  |   /    \  /    \
  |  /      \/      \
  +-------------------> Time
  Base

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.

Parameter

  |   /\      /\
  | /   \   /   \
--+------\-/------\-/---> Time
  |       V        V
  Base (center)

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.

Parameter

  +-------------------> Time

  |    \  /    \  /
  |     \/      \/
  v

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%.

Navigating Between Amplitude Modes¶

The amplitude mode work together as a single continuous control. Starting in Add (Positive) mode lower the amplitude to reach zero and then press the ↓ button, this will switch to Bipolar (Center) mode. Continue to press down to reach zero in Bipolar mode, then press the ↓ button again, to switch to Sub (Negative) mode.

Shape¶

Selects the waveform shape used for modulation:

Shape	Description
Sine	Smooth, natural modulation
Triangle	Linear rise and fall
Saw Up	Rising ramp
Saw Down	Falling ramp
Expo Up	Rising exponential ramp
Expo Down	Falling exponential ramp

Shape Modifiers¶

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

S - Sync

When enabled, the LFO resets every time a note is played
Useful for consistent modulation at note (like an envelope)

L - Loop

When enabled, the LFO continuously cycles
When disabled, the LFO runs once per note (like an envelope)

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 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	Free-running single cycle (LFO is disabled at the end of the running cycle)

Envelope Mode¶

When Sync is ON and Loop is OFF, the LFO acts like an envelope:

Triggers on each note
Runs through one cycle
Stays at final value until next note
