QuotaFX is a hands-on performance-effects instrument for iPhone and iPad. Run it as a standalone app, or load the AUv3 on a channel or bus inside COMPA, AUM, Cubasis, Drambo, Loopy Pro, Logic Pro for iPad, GarageBand, or another Audio Unit host. TWO PERFORMANCE MODES SP Mode keeps the focused hardware-style workflow: choose one effect, work with six consistent CTRL macros, and jump between sixteen assignable favorites. Browse the complete library through the MFX pages, and choose whether the on-screen MFX button works as Hold or Latch. Chomp Mode is a simultaneous multi-effect engine. Its 48 assignable positions process in visible top-left to bottom-right order. Ride the complete tile with a finger or mouse, combine several effects at once, use HOLD when you want a gesture to stay active, and show 8, 16, 32, or all 48 positions with paging that never changes the underlying effect chain. TUNE THE WAY EACH RIDE MOVES Choose any position, assign an effect from the full catalog, move or swap complete positions, and map up to four parameters to one finger movement. Set From and To endpoints, reverse a ride by swapping them, and choose Linear, Fine, Punch, Smooth, Log, or stepped response. Save named Chomp setups in a shared on-device library, load them in another host, and export or import setup files between devices. Choose an optional starting setup for new instances. Existing projects always restore their own saved tuning. 48 EFFECTS The library covers filters, isolators, delays, reverbs, modulation, distortion, lo-fi texture, pitch, repeats, freezes, throws, tape movement, glitch and performance transitions. Version 1.3 adds: - Shuttle - ride captured audio through reverse, stop, normal speed and double speed. - Reflex - transient-reactive pre-hit capture and repeat. - Wrap Filter - resonant bands that travel and wrap through the spectrum. - Contour - shape a sound between attack and body. MAKE SP MODE YOURS Set every CTRL to a knob, vertical fader or horizontal fader, or choose a different shape for each of CTRL 1 through 6. Show boolean controls as direct ON/OFF buttons or Classic 50% controls. Set every supported effect switch to Toggle or Momentary together, or change only the switch owned by the selected effect. SCOPE GLASS See the processed signal behind the performance surface with Peaks, Wave, Bars, Spectrum, Vector, Depth, or Trace. Choose clear, glass, or solid Chomp tiles, then use a flat, gradient, rainbow, or custom one-to-three-color scope palette. RECORD WITHOUT A HOST Connect a class-compliant USB-C groovebox or audio interface, monitor through the selected output, perform through QuotaFX, and record the post-effect result directly as a 24-bit WAV. Export the newest take from Settings or find it later in Files. BUILT FOR HANDS-ON CONTROL - Six MIDI-mappable SP CTRL macros - Sixteen assignable SP favorites with Select, Toggle, or Hold behavior - Toggle and Momentary modes for supported effect switches - In-plugin MIDI Learn - Responsive portrait and landscape layouts - Standalone app plus AUv3 extension QuotaFX is a free download with one non-consumable unlock. Brand-new production users purchase to unlock processing. If this device has a real QuotaFX trial record from an earlier release and has not been unlocked, version 1.3 grants that existing record one fresh seven-day window exactly once. No subscription. No Rare Data account. No analytics or tracking. QuotaFX is built and supported by one independent developer. Questions, issues, feedback and feature requests are welcome at support@getquota.app. COMPA is Rare Data's producer-first AUv3 host and music workstation. It launches alongside QuotaFX 1.3 on September 9. Run QuotaFX on a COMPA channel or bus, then build the rest of the track around it.

The theremin, reinvented on your iPhone. Play it in the air with your hands, no touch. Hoverophone is a theremin you actually play by waving your hands in the air. Point the front camera at your hand and move; there is no touch, no controller, no tapping glass. Raise and lower your hand to glide the pitch, spread your thumb and finger apart to swell the volume, slide left to right to pan. It is the eerie, sci-fi theremin sound, played with a wave of the hand. Wondering how to play the theremin, or whether the theremin is hard to play? This is the easiest way to start: raise a hand and you are already playing. A REAL SYNTH, AND POLYPHONIC Continuous synth voices, sine, triangle, saw and square, with drive and ring modulation in stereo, from a soft ambient pad to a metallic, otherworldly drone. It tracks up to four hands at once, so a theremin can finally play chords, and you can pin voices in place to hold up to twelve notes ringing together. Tune the sound with one hand while you play with the other. MICROTONAL, PLAYED IN THE AIR Turn on the note grid and your in-air pitch snaps to a scale: 12-TET, or 24-TET quarter tones for real microtonal play. It is an isomorphic, honeycomb hex keyboard you play in the air, not by tapping glass, so every note lands in tune while your hands stay above the camera. Explore microtonal music, quarter tones and xenharmonic scales the moment you raise a hand, or leave the grid off and glide freely for the pure continuous theremin. WHAT YOU CAN DO - Play a real theremin in the air, front-camera hand tracking, no touch - The classic continuous theremin glide, the sci-fi movie sound - An in-air microtonal keyboard: 12-TET or 24-TET quarter tones on an isomorphic hex grid, or fully continuous - Polyphonic: up to four hands live, and pin voices to stack up to twelve - Synth voices with drive and ring modulation, stereo panning as you move - Plays through the speaker or headphones, even on silent - Fully offline: no account, no network, no data collected, the camera is processed on device and never leaves it No presets, no wall of knobs, just your hand and the air. Fill a room with an ambient drone, improvise a generative soundscape, or conjure the spooky whine of a sci-fi movie. Works best in a bright room where the camera can see your hands.
