About QuotaFX (AUv3)
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 [email protected]. 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.
