PolyrhythmLab vs MIDIHuman Comp

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. NEW IN 2.0 — AUv3 PLUGIN Use PolyrhythmLab as a real instrument inside GarageBand, Logic, AUM, and any other AU-compatible host. Four independent polyrhythmic layers, each exposed as automatable parameters, real MIDI output so your performance actually records as a MIDI region, and its own compact control panel with a live pattern wheel, a randomizer, and optional sync to your session's tempo. NEW IN 2.0 — LIVE MIDI OUTPUT Send a real Note On/Off for every layer hit straight from the main app — one MIDI channel per layer, over a virtual MIDI connection — to drive another synth, app, or piece of hardware in real time, not just sync tempo. NEW IN 2.0 — CAST VJ MIX 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. Save and reload VJ Mix setups — visual styles, effects, camera moves, and their LFOs — as named presets, same as patterns. 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. PRESETS Save and reload both groovebox patterns and VJ Mix setups 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.

MIDIHuman Comp is an AUv3 MIDI processor for the chord part — organ, piano, pads, guitar. It makes no sound of its own: your chords go in and come out on their way to your instrument, played the way a comping player would play them — a little different every time round. It never writes new chords for you. It works on top of what you play: variations happen only on the steps you mark, only as often as you set, and always on the chord your loop plays there. HUMANIZE AND GROOVE - A chord lands a little late now and then — the whole chord together, never smeared into a strum — and velocities move - Quantize toward a grid and add swing LEARN - Hears the key — or set it yourself - Remembers the chord on every 16th (up to six notes each), in loops of 1, 2, 4 or 8 bars, and names it - PLAY keeps the learned chords going by themselves; FREEZE keeps them exactly as they are VARY AND FILL - On a chord: an octave on top, the next inversion, a top note that leans and resolves, a staccato chop, a re-strike - Between chords: organ stabs, and chords that arrive early - Eight chord fills — inversion climbs and drops, stabs, triplet stabs, doublings, a drop-out, an anticipation. Tap FILL or set Auto Fill - Swaps: move everything an octave, or spread the voicings from close to open PRESETS - Factory presets: Organ Stabs, Gospel Push, Soft Pads, Funk Chops, Harmony Lines - Your own presets and stored chord loops; host parameters for automation - A searchable User Guide inside the plug-in WITH THE MIDIHUMAN FAMILY Load MIDIHuman Drums, Bass or Lead in the same host session and they find each other: one shared groove, fills that start and hit together, and a FOLLOW fader for each sibling. - One shared key with Bass and Lead; voicings kept above Bass and below Lead - Sends your chords to Bass, so its walks and fills follow your changes - Harmonize: now and then doubles Lead's line a 3rd or 6th below - With Drums: lean on the kick and sit in its pocket Each MIDIHuman app is sold separately and works on its own. REQUIREMENTS - An AUv3 host that loads MIDI processors and provides tempo and transport. Tested in Loopy Pro. - A chord sound after it — an AUv3 instrument, another app or hardware. - Without the host's clock it still humanizes; learning, variations and fills need the clock. - iPad and iPhone.
