Luanco Chorus
You’ve never heard
a chorus like this.
Reverse it. Scatter it. Freeze a moment from one MIDI note. Play the feedback with another, then draw a rhythm that bends the texture across four bands. Choose direct Texture or feed it into six chorus voices per band, with independent Dry and Wet.
AUv3 audio effect · macOS 15 or later on Apple Silicon · iPadOS 26.2 or later (iPad only) · compatible AUv3 host application required
Take Chorus to the extremes.
Three factory examples and six modified demonstrations from the earlier 2.0 preview, all fully wet.
Preview media: native Mac screenshots from 7 October and the film from 14 October 2026. These show earlier builds; final 2.0 release media and physical-iPad demonstration evidence are pending.

Frozen Glass — performed
Modified demonstration
Preserve Pitch 0× · 15 ms grains · Pitch +24 · Scatter 55% · Repeat 90% · Reverse 35%.
MIDI note 60 gates a 4,000 ms capture at four seconds; velocity drives Pitch and aftertouch drives Grain Size.
Mutating Breaks — four extremes
Modified demonstration
Four bands: +0.08/−4/0/+4× · pitches −24/+7/+24/+12 · grains 1,000/35/5/8 ms.
Independent Rhythm, host-fragment and source-transient timing combine strong Scatter and Repeat.
Sidechain Metal — attack driven
Modified demonstration
Preserve Pitch +0.5× · 12 ms grains · Pitch −12 · Capture 90% · Ring 95% · Cross Feedback 85% · Feedback 80%.
Routed host sidechain audio drives transient fragments and negative envelope-to-Speed, with fast Spectral and rhythmic Pitch.
Feedback Bloom — played network
Modified demonstration
Two Texture → Chorus bands · six voices · +0.15/−0.25× · Pitch +12/−12 · 75/1,000 ms grains · Feedback/Cross Feedback 95%.
Reciprocal bands, opposing Barberpole, Spectral and MIDI feedback pitch combine velocity-to-Pitch and aftertouch-to-Scatter.
Earlier 2.0 preview renders from 7 October 2026; final release demonstrations are pending. Same 48 kHz stereo phrase: eight seconds of input and four seconds of tail, 128-frame blocks at 160 BPM. Examples use Dry 0%, Wet 100%, active Band Mix 100%, Ultra and saved seeds. The six modified demonstrations inherit unlisted settings and curves from their named factory presets. One shared downward gain keeps every export below −1 dBFS; no added limiter or compression. Render settings, routing and provenance.
More than a chorus. Another instrument in your hands.
Freeze a phrase, pull it apart, and perform its texture with notes, velocity and aftertouch.
Every way to shape the sound.
From a quiet sway to restless motion and broken-up textures, find the controls that fit the feeling.
Up to four moving bands
Split and join four frequency ranges with independent paths, mixes, motion and MIDI mappings.
Read the control guide →Frequency filter
Global wet Tone shapes the combined band return with Low Cut, High Cut and slope; Dry stays unchanged.
Read the control guide →Voice spread
Use up to six normalized stereo voices in Chorus and Texture → Chorus, from tight doubling to an ensemble.
Read the control guide →Ensemble / Drift / Swarm
Add flutter, independent drift and coupling between voices in the two chorus paths.
Read the control guide →Barberpole Rise / Fall
Keep delay heads climbing or falling; Rate sets speed and Depth sets range in the chorus paths.
Read the control guide →Orbit
Move chorus voices around stereo with a speed independent of Rate; direct Texture skips the voice bank.
Read the control guide →Rhythm
Draw a clocked curve for any of nine band targets, including Speed, Grain Size and Pitch.
Read the control guide →Host or MIDI clock rate
Run Rhythm from host transport or MIDI clock. Note Gate additionally needs held MIDI notes routed to Chorus.
Read the control guide →Step editor
Place points freely, use stepped or smooth segments, and retain an independent curve for each band.
Read the control guide →Freeze
Hold 20–4,000 ms of recent input. Keep sustains it; Add overdubs Capture Blend and feedback.
Read the control guide →Freeze note from MIDI
Learn one key to gate or latch capture, with its own release back to live audio. Captured audio stays temporary.
Read the control guide →Reverse
Reverse each newly launched fragment by probability, on top of signed playback Speed.
Read the control guide →Scatter
Jump through four seconds of recorded history, then use Repeat to keep selected fragments returning.
Read the control guide →Spectral chorus
Add moving frequency notches and detuning after any selected wet path, before global Tone.
Read the control guide →Feedback with MIDI pitch
Play feedback intervals in the chorus paths. Direct Texture uses Grain Pitch instead of the separate return shifter.
Read the control guide →Sidechain
Gate or duck Depth, Band Mix or both from input or host sidechain; this detector is separate from Interaction.
Read the control guide →Velocity
Map note velocity to one of nine band targets with bipolar amount and separate attack/release.
Read the control guide →Aftertouch
Use channel or latest-note poly pressure on a second target, alongside velocity.
Read the control guide →Dry/Wet
Balance original input and the processed return with independent levels; Band Mix remains separate.
Read the control guide →Processing Paths
Choose Chorus, direct Texture or Texture → Chorus independently for every band.
Read the control guide →Tape/Preserve Pitch
Tape couples pitch to Speed. Preserve Pitch separates grain pitch from movement, including stationary textures.
Read the control guide →Pitch/Repeat/Randomness
Tune grains ±24 semitones, relaunch fragments with Repeat and save deterministic Random Seeds.
Read the control guide →Fragment Timing
Launch 5–1,000 ms grains freely, on straight or triplet host divisions, or from source attacks.
Read the control guide →Interaction
Blend another source into capture; let its envelope, ring modulation and cross feedback reshape the return.
Read the control guide →Live Activity
Read selected-band Motion, Texture, Spectral, Dynamics, Freeze, Interaction or Rhythm telemetry.
Read the control guide →Feature controls are native Mac preview captures from 7 October 2026; capture provenance. Final release screenshots are pending. A compatible AUv3 Music Effects host application (software) with audio input routing is required. No external hardware or pairing is required. The container app does not process audio on its own. Supported systems: macOS 15 or later on Apple Silicon, iPadOS 26.2 or later (iPad only).

Brake, stop and reverse
Start with Brake / Reverse and run host transport. Its saved Speed curve moves through zero; Tape fades silent there, while Preserve Pitch holds grains.
Read the control guide →Perform a captured phrase
Load Frozen Glass, choose a MIDI Freeze Note, then combine velocity-to-Pitch with aftertouch-to-Grain Size. Capture audio again after reopening a project.
Read the control guide →Make bands interact
Load Feedback Bloom for reciprocal sources, or route a host sidechain to Sidechain Metal. Capture Blend changes recorded audio; Ring and Cross Feedback change the wet return.
Read the control guide →Common questions.
Do I need an AUv3 host application?
Yes. The host is a software application. Load Luanco: Chorus in a compatible AUv3 Music Effects host application and route audio into it. No external hardware or pairing is required. Host names and slots vary; some hosts list Music Effects as MIDI-controlled effects. The container app explains setup but does not process audio on its own. Read the guide →
Are the Mac and iPad versions the same purchase?
No. They are separate native apps and separate purchases. Mac needs macOS 15 or later on Apple Silicon; iPad needs iPadOS 26.2 or later (iPad only). Both require a compatible AUv3 Music Effects host application (software). Read the guide →

Will Freeze recall my captured audio?
No. Presets and host projects never save captured audio or held notes. Manual Freeze restores Off; MIDI Freeze can restore armed. Capture Length spans 20–4,000 ms. With no history, live playback continues until enough audio has been recorded to capture. Read the guide →
Does Spectral add latency?
Yes. Enabled Spectral adds a 1,024-sample wet-path window: about 21.33 ms at 48 kHz, even at Amount 0%. Dry stays immediate and the AU reports zero fixed latency. See the fresh 2.0 measurements and their conditions. Read the guide →
Can I play Chorus with MIDI?
Yes, when a compatible host routes MIDI to the effect. Choose one channel for the instance, learn a Freeze Note, map velocity and aftertouch to nine targets, play feedback pitch and run a host- or MIDI-clocked rhythm curve. Host Rhythm needs running transport; Note Gate also needs held notes. Read the guide →
What is the difference between Texture and Texture → Chorus?
Texture plays two overlapping stereo fragments directly and skips chorus voices, Barberpole taps and the separate feedback pitch shifter. Texture → Chorus feeds those fragments into the voice bank. Both support signed Speed, Grain Pitch, Repeat, Scatter and the selected interaction source. Read the guide →
What happens at Speed zero?
Tape fades to silence. Preserve Pitch repeats stationary grains at the independent Grain Pitch. Negative Speed moves backward; Reverse sets the probability of reversing each newly launched fragment. Read the guide →
Does Interaction use the Dynamics sidechain source?
They are separate. Interaction selects main input, a Chorus band or Host Sidechain for Capture Blend, envelope motion, Ring and Cross Feedback. Dynamics selects a detector that scales Depth or Band Mix. Unavailable interaction sources contribute silence; Workhorse also offers layer sources. Read the guide →
