About

PolyrhythmLab

Features
Read full description

PolyrhythmLab is a groovebox built around true polyrhythms: every sound layer gets its own step count, pulse count, and rotation, so layers of different lengths interlock and drift in and out of phase instead of locking to one shared grid. GROOVEBOX • Euclidean-style rhythm engine — set steps, pulses, and rotation per layer • Drums, glitch/textural one-shots, classic synth voices (piano, bell, pad, bass), and melodic synth patches • Per-layer filter, reverb, delay, pitch, and LFOs on every parameter • Randomize engine biased toward musical, playable combinations • Chord modes, scales, and modal note selection for melodic layers SONG MODE Arrange your saved patterns into sections and chain them into a full song. VJ MIX A live visual performance surface: blend two audio-reactive visualizations, layer on real-time color and shader effects — RGB split, kaleidoscope, pixelate, glow, trail — and a 3D camera with zoom, pan, orbit, and tilt, each with its own LFO. Randomize the whole look by hand, or hand it to an autonomous "robot" that keeps remixing itself. Record the performance in real time via ReplayKit, or export a styled video clip. CAST TO ANY SCREEN Send the VJ Mix visuals to a TV or projector over AirPlay or a wired adapter, while your device keeps the full set of live controls. PRESETS Save and reload both groovebox patterns and VJ Mix setups — visual styles, effects, camera moves, and their LFOs — as named presets. EXPORT Render your patterns and songs to audio, or export them as MIDI. No account, no ads, no analytics. Everything is stored locally on your device.
