About

ON'NENIKUR

Read full description

ON'NENIKUR is an octave-freeze reverb app for iPhone and iPad. It can be used as a standalone audio app or as an AUv3 effect inserted into compatible host apps such as GarageBand. This processor blends standard-pitch reverb with a pitch-shifted dry signal before applying modulation, filtering, envelope shaping, and dry/wet mixing. “DARK” shifts the original sound down an octave to create a rich, spacious sound, while “LIGHT” shifts it up an octave to produce a brighter, more ethereal sound. “FREEZE” transforms the reverb tail into a playable hold texture. Features - Octave-down (DARK) and octave-up (LIGHT) reverb - Two reverb paths: standard pitch and pitch-shifted - FIR (chorus-style) and OAK (phase-style) modulation modes - RISE (swell) and FALL (standard envelope) - Adjustable filter, decay, mix, octave level, depth, rate, and output - “FREEZE” for creating sustained textures and drone sounds - Instrument input mode and line input mode - 2x and 4x processing modes to control the quality of the octave shift - Standalone iOS/iPadOS app - AUv3 audio effect Trial Before Unlocking The trial version of this product is designed to allow 10 minutes of active use of all features across both the standalone app and the AUv3 plug-in. A one-time, non-consumable in-app purchase unlocks unlimited use in both formats. The “Restore Purchase” feature is also available in the standalone app. ON’NENIKUR is designed for shoegaze, ambient, post-rock, and any arrangement where guitars, synthesizers, vocals, and reverb are integral parts of the song’s composition.

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. 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.
