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.
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.
Continuous movement, seven shapes, random modes, full control over the range, speed, and offset of the targeted parameters.
Volume that swells and recedes like it's alive — ambience that ebbs and surges instead of sitting still.
Subtle pitch drift that choruses a sound against itself, or wild tape-stop dives and seasick warbles.
Drive a whole bank of faders at once in phase-offset motion — hypnotic to watch, generated live from one rack.
Moves QLab's audio object through the room — position, arc, orbit — driving the Yellow Dot live.
A playhead sweeps your loudspeaker array — up to 32 channels — building rotating sweeps and circular panning live.
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.
Download free and keep the Fader unit forever. Every paid tier unlocks all five Target Units.
