How Does It Work?#

Chorus is a stereo, BBD-leaning modulation effect that thickens a signal with moving delay voices, then lets you shape the result with mix, width, tone, spread, jitter, and drive.

Quick Overview#

• It is a stereo effect with In L / In R and Out L / Out R.
• NQ and HQ switch between the two chorus engines.
• Rate, Depth, and Delay set the core motion.
• FB, Tone, and Drive shape the character of the repeats.
• Width, Spread, and Jitter control how wide, separated, and unstable the modulation feels.

Inputs And Outputs#

Port	Type	What It Does
In L	Audio	Left audio input.
In R	Audio	Right audio input. If unpatched, it follows In L.
Rate	CV	Modulates the chorus rate.
Depth	CV	Modulates modulation depth.
Delay	CV	Modulates the base delay time.
FB	CV	Modulates feedback amount.
Out L	Audio	Left processed output.
Out R	Audio	Right processed output.

Controls Reference#

Control	Values	Default	Behavior
Quality	NQ, HQ	NQ	Selects the normal or high-quality chorus engine.
Rate	0.03..8 Hz	0.45 Hz	Sets how fast the chorus moves.
Depth	0..1	0.42	Sets modulation depth.
Delay	3..35 ms	11 ms	Sets the base chorus delay time.
FB	-0.35..0.35	0.08	Adds positive or negative feedback for a thicker or more hollow tone.
Mix	0..1	0.5	Blends dry and wet signal.
Width	0..1.25	1	Scales stereo width on the wet path.
Tone	1200..12000 Hz	6200 Hz	Sets the brightness of the chorus color.
Spread	0..1	0.65	Increases divergence between the modulation voices.
Jitter	0..1	0.18	Adds slow drift so the movement feels less static.
Drive	0..1	0.15	Pushes the wet path into soft nonlinear color.

Character Notes#

• Rate, Depth, and Delay define the basic chorus motion.
• Spread and Width do different jobs: Spread changes how separated the moving voices are, while Width changes how much stereo side energy reaches the output.
• Tone darkens or brightens the wet signal and also affects the feedback color.
• Drive adds saturation after the wet signal is bandwidth-limited, so it behaves more like character shaping than simple gain.
• HQ is the smoother, richer option. NQ is lighter and more straightforward.

Patch Notes#

• Start around Rate 0.3..0.8 Hz, Depth ~0.4, and Delay 10..14 ms for classic chorus territory.
• Reduce Tone and raise FB for darker, more vintage movement.
• Push Spread and Width together when you want a broader stereo image.
