WHAT IT IS Disto Disco turns distortion into movement. It starts with gentle drive and classic distortion, then ventures into stranger territory: degrading echoes, vocoders, morphing vowels, spectral effects, ring modulation, granular clouds, and more. Every dial can move with the beat, while Random and Spice can send the whole patch somewhere new. Shape something smooth, tuned, and shimmering; push it toward harsh, brutal, and broken; or take it somewhere weird and otherworldly. WHAT IT DOES * 28 sound-shaping modes: explore five distinct sonic territories, each with its own controls and character. * Drive: move from gentle warmth through folding, fuzz, bit crushing, and high gain. * Spectral: filter, morph, vocode, swap, or silence different parts of the sound. * Math: combine versions of the input with simple mathematical operations for raw, harsh, and unusual textures. * Time: turn recent sound into echoes, loops, and resonances, then bend, shift, or scrub it into motion. * Granular: cut sound into tiny pieces and scatter, repeat, or layer them into sparse grains and dense clouds. * A modulator on every dial: draw a 16-step pattern, choose a shape, or generate one, all synced to the beat. * Random and Spice: generate a new direction for the whole patch, from subtle changes to complete chaos. Keep what works and refine the rest by hand. * Tone and dynamics: shape the effected signal with Low Cut, Tube, and High Cut, then use the envelope follower to make distortion react to the input. * AUv3 and standalone: use Disto Disco as an effect inside your favorite host, or process live input directly in the app. REQUIREMENTS * An AUv3 host such as AUM, Cubasis, Drambo, GarageBand, Loopy Pro, or Logic Pro.

Read full description

Bent Spool is a creative effect that can transform simple musical parts into unexpected rhythms and melodies, played live or as an effect in your favorite host app. Shape a tremolo pulse, turn a note into a run of pitched repeats, or build a moving layer from fragments of what you just played. Drive the input with built-in overdrive or fuzz, add a core effect, then finally layer in vintage analog tape effects. THREE MODES TREM: a pulsing volume effect, from a rounded sine through triangle and sawtooth to a hard square gate. Syncs to your host's tempo or runs free. REPEAT: up to 64 pitched copies with their own decay and feedback, across five pitch stations from two octaves down to two octaves up. LOOPS: up to six overlapping fragments of your recent audio, spread across pitch, direction, read position and the stereo field. CHARACTER CHAOS adds movement that suits each mode: octave jumps in REPEAT, held or stalled pulses in TREM, wandering reversals and pitch drift in LOOPS. WEAR adds tape wear, magnetic saturation and digital crush after the active mode. At the input, OD is a softer clip; FUZZ is a harder distortion that sputters as it decays. PRESETS 48 factory presets: 10 TREM, 15 REPEAT, 15 LOOPS and an 8-preset Fuzz Tremolo pack. Unlock to save your own. FREE TO TRY TREM plays in full on the OD voice with ten presets. No time limit, no interruptions. A single $9.99 in-app purchase unlocks REPEAT, LOOPS, FUZZ, the rest of the presets and preset saving. No subscription. Runs as a standalone app or as an AUv3 effect in AUM, Loopy Pro and other AUv3 hosts, on iPhone and iPad.
