LFO Rack adds continuous, shapeable motion across your QLab faders, play rate, and spatial position — from subtle gestures to lively animation — with reliable randomness that keeps a loop from ever sounding like a loop.
Each Oscillator can drive several Target Units that control QLab parameters in real time. Easily link LFO Rack to Qlab using the Detect function.
Continuous movement — seven LFO shapes, random modes, full control over the range, speed, and offset of the targeted parameters.
Volume that swells and recedes, in regular or irregular intervals — sound that never sits still.
Pitch drift that can chorus a sound against itself, or create wild tape-stop dives and seasick warbles.
Drive a whole bank of faders or crosspoints at once. Use phase-offset and random modes to subtle or wild effect — hypnotic to watch, generated live from one rack.
Uses Qlab's Object tab to move QLab's "audio object" (the yellow dot) continuously around a space.
A proximity dot sweeps around custom loudspeaker positions — up to 32 channels: linear and circular spatial audio movement.
Wind never gusts the same way twice. No tide comes in quite the same. LFO Rack brings reliable irregularity to your design — from one rack of integrated controls.
