Stone Echo vs PolyrhythmLab

Echo effect Audio Unit V3 inspired by the mayan pyramids acoustic echo. I come up with a complex phase modulated frequency of the echo so you can change it’s frequency signature. It is kind of changing the material of the reflective surface and I called it “Stone F”. I have made the echo to sound more music friendly to me but there is button called “UFO” and if you press it the effect is more close to the mayan just shifting the frequency backwards (I liked that better). You can also control the feedback of the phase modulation. The effect can work as a stand alone app and as an audio unit AUV3 plug-in. Stone Echo is an effect that is heavy on the CPU Controls: - Time - time offset of the echo - Stone F - frequency response of the echo - Feedback - echo feedback - Level - the volume of the echo - UFO - heavy modulated echo

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.
