Save your own for any engine • DRUM KIT: ten drum slots in one instrument — eight built-in kits, or build your own from any sound or sample • Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable and the dual-oscillator MODX, plus DRUM, an analog drum voice • WOVEN, a macro-oscillator with 24 models and 96 classic DX7 patches; ROUND, a resonator for strings, bars and bells; MODAL for struck percussion • SAMPLER: record or import, chop at transients, stretch to the tempo, loop, reverse, round-robin • SPEECH sings your lyrics in English and Japanese; GRAIN turns any recording into clouds; DRONE, RESONATOR and TEXTURE build ambient beds • AUv3 hosting: play your instrument plug-ins and insert effect plug-ins on any channel SHAPE • 32 effects on any note: delays, reverbs up to thirty seconds, tempo-synced gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps, FOGGY granular clouds and more • AUT automation morphs an instrument and its effect across the rows • RANDOM dice, tables for instant arpeggios, a groove editor per instrument, scale lock • A twelve-channel mixer with volume, pan, mute, solo and plug-in inserts PERFORM • LIVE MODE: launch phrases from six scenes on pads, quantized to the beat or the bar, and punch in delay and filters — or latch them CONNECT • MIDI in with step and live recording, MIDI out to hardware, MIDI clock and Ableton Link KEEP • Render to WAV (16 or 24 bit), stems and MIDI; share songs as files; your session autosaves • A lock-screen player with cover art in your theme • 28 themes — the studio look comes in dark and light and can follow your device — a theme editor, seven typefaces, hex numbers if you like • English and Japanese, and a demo song to start from Everything runs on your device.

Features
Read full description

GlitchShredder is a glitch and stutter effect for iPhone and iPad, available as a standalone app and as an AUv3 plugin for GarageBand, AUM, Cubasis, Logic Pro for iPad and other compatible hosts. At its core is the Chopper: it captures fragments of the incoming audio, repeats, reverses and recombines them in real time, turning any source — vocals, drums, synths, guitar — into unpredictable glitch textures or tightly synced stutter rhythms. KEY FEATURES • Independent stereo chopper: L/R channels with 16 segment slots each, for natural glitch divergence and organic stereo width. • Chaos and Glitch Probability: from predictable behavior to total chaos, with spontaneous segment jumps adjustable in probability and rate. • Reverse Probability and ZC Reverse: random segment reversal, or ping-pong mode that flips direction at the end of every segment. • Stutter Sync: automatic sync to the host tempo (AudioPlayHead) with manual BPM fallback and built-in Tap Tempo. 9 rhythmic subdivisions, from 1/4 to 1/64 plus triplets and dotted values. • Quantized Jumps: locks spontaneous glitch jumps to the beat grid for chaos that stays in time. • Transient Snap: detects transients in the input signal and forces a new segment on every hit, with adjustable sensitivity threshold. • Segment Leveler: per-segment RMS normalization to smooth out level jumps between loud and quiet fragments. • Bit Crusher and Sample Rate Reduction: post-chopper digital degradation for lo-fi textures, from subtle to destroyed. • Drive: output soft clipper with a tanh curve, for progressive, controlled saturation without hard clipping. • Equal-power Dry/Wet and independent Input Gain control. • Single Win mode: a single capture slot for a continuous loop, freeze/looper style. • MIDI: any Note On triggers freeze; notes C3–D#4 jump directly to slots 1–16. • Real-time visualization: oscilloscope with dry/wet overlay colored by active slot, plus a 2×16 segment grid with waveform preview. PRESETS AND INTERFACE GlitchShredder ships with a ready-to-use factory preset library, managed through the 34AudioLibrary system (.a34 format): folder organization, quick search, and the ability to save your own settings. Presets are compatible with the desktop version of the plugin. The touch-first interface offers knobs with vertical drag for coarse adjustment, horizontal drag for fine adjustment, double-tap to reset to default, and long-press for manual value entry. The panel supports pinch-to-zoom up to 2.5x, while the preset bar and controls stay accessible at all times. A live help pop-up on the knob or a bottom info bar (your choice) shows the description of each parameter. WHO IT'S FOR GlitchShredder is built for producers, DJs, sound designers and musicians who want to add glitch, stutter, granular or lo-fi elements to their productions directly from iPhone or iPad — in the studio or on the go, standalone or integrated into your favorite AUv3 setup. No account required, no connection needed to use the plugin.
