QuotaFX is an audio effects app and AUv3 plug-in for iPhone and iPad. Version 1.4 includes 64 effects and three modes in every instance. SP MODE Choose one effect from the MFX list or 16 favorite pads. Adjust six CTRL parameters with knobs, vertical sliders, horizontal sliders or switches. Use momentary or toggle actions, MIDI Learn and host automation. CHOMP MODE Control several effects with performance sliders. Tune a gesture to move up to four parameters, set its endpoints and response curves, and use HOLD to keep your amounts. Eight A-H banks recall separate combinations across the same effect order and pages. Show 8, 16 or 32 tiles at a time and page through all 64 effects. NEW RACK MODE Build a chain of up to eight independent inserts. Audio passes from the first insert to the last. Reorder effects, bypass individual inserts and reach each effect's six controls. Your host saves the chain and its settings with the session. 16 ADDITIONS 303 VinylSim, Dub Matrix, Grain Stretch, Buffer Shuffle, Feedback Drive, Pitch Ladder, Band Shuffle, Spectral Smear, Twin Drift, Spectral Delay, Ring Motion, Orbit, Carrier, Reverse Room, Body Print and Spectral Gate. UPDATED EFFECTS This release revises DJFX Looper, DJFX Delay, Super Filter, Backspin, Scatter, Isolator, Cassette Sim and JUNO Chorus while retaining parameter identities and existing presets. IN YOUR HOST OR ON ITS OWN Use QuotaFX in COMPA or another compatible AUv3 host. Load separate instances on tracks and buses, with a different mode and effect selection in each instance as your host and CPU allow. The standalone app processes your selected audio input and records the result as a 24-bit WAV. Choose seven scope views, steel and wood surfaces, color palettes and Scope Glass behind the controls. Save named CHOMP setups and import/export .quotafxsetup files between devices. The iPhone/iPad processing unlock is a one-time App Store in-app purchase, separate from a desktop license. Existing purchases remain unlocked. Version 1.4 does not introduce an additional trial reset. Audio processing is local to your device. Incoming audio is required; no backing track is included.
