Living automation for QLab · macOS

Let your shows
breathe

LFO Rack adds continuous, shapeable motion across your QLab faders, play rate, and spatial position — from subtle gestures to lively swings — with reliable randomness that keeps a loop from ever sounding like a loop. Living motion you'd spend hours programming, now just a few sliders away.

LFO Rack — spatial target

Living motion, target by target.

Each Target Unit is an LFO that drives a class of QLab parameter in real time over OSC. Build a rack of them instead of programming a thousand cues by hand.

LFO

Oscillate

Continuous movement, seven shapes, random modes, full control over the range, speed, and offset of the targeted parameters.

Fader

Breathe

Volume that swells and recedes like it's alive — ambience that ebbs and surges instead of sitting still.

Rate

Quaver

Subtle pitch drift that choruses a sound against itself, or wild tape-stop dives and seasick warbles.

Multi

Serpentine

Drive a whole bank of faders at once in phase-offset motion — hypnotic to watch, generated live from one rack.

Object

Wander

Moves QLab's audio object through the room — position, arc, orbit — driving the Yellow Dot live.

Spatial

Surround

A playhead sweeps your loudspeaker array — up to 32 channels — building rotating sweeps and circular panning live.

Imperfection by design

Nothing real ever loops perfectly.

Wind never gusts the same way twice. No tide comes in quite the same. LFO Rack brings that living irregularity to your show — a different breath every night, from one rack of oscillations.

Real-time OSCTalks to QLab over your local network. No plugin, no audio in your signal path.
Runs offlineNo internet, no phone-home. Nothing in the chain that can fail in a venue.
Saves like QLabAutosave and rolling timestamped backups — the workflow you already trust.
One rack, not a thousand cuesWhat took hundreds of Script cues becomes a handful of Target Units.

Questions

Frequently Asked Questions.

Do I need QLab?

Yes. LFO Rack is intended to be used alongside QLab, ideally on the same computer. It doesn't replace or include QLab.

Does it need an internet connection?

No. LFO Rack runs on your show computer and communicates locally over OSC. License activation is done offline.

Which Macs does it run on?

macOS 11 (Big Sur) and later, on both Apple Silicon and Intel.

How does licensing work?

Your license key is generated from your computer's hardware ID and activates offline. Paid tiers cover two computers — a primary and backup show computer.

Is this made by Figure 53?

No — LFO Rack is independent, and not affiliated with or endorsed by Figure 53. We're big admirers of QLab, and built LFO Rack to complement it. "QLab" is their trademark, used here only to describe interoperability.

Can I get a refund?

The free Lite tier and 14-day trial let you evaluate fully first. See our Refund Policy for the details.
