About

FALSE MEMORY

This app transforms any sound into a decaying audio effect, simulating tape degradation or digital corruption. Explore various destruction parameters to create unique sonic textures and atmospheres. It can also evolve the sound automatically over time.

Highlights
  • Real-time audio disintegration
  • Analog/Digital destruction engine
  • Pitch and timing destabilization
  • Frequency spectrum smearing
  • Past audio bleed-through
  • Automatic evolution over time
  • Randomize parameters

FALSE MEMORY is a real-time audio disintegration effect. Feed it any sound and watch it decay. A tape left in the sun. A corrupted file half-recovered from a dead drive. A memory dissolving as you try to hold onto it. Turn up MEMORY and the destruction begins. Everything else shapes how the sound falls apart. DESTRUCTION ENGINE The Analog / Digital slider is the soul of the effect. Slide left for warm, organic decay: Cassette wobble, Reel-to-reel saturation, VHS tracking errors. Slide right for cold, precise corruption: Lo-fi aliasing, Circuit-bent glitches, Data-mosh block artifacts. Drift destabilizes pitch and timing. At low settings it breathes. Cranked up, the signal loses its grip on reality. Damage controls how aggressively the signal gets torn apart. ATMOSPHERE Fog smears the frequency spectrum into clouds. Three modes: Tonal keeps harmonic structure intact, Inharmonic scatters it, Evolving slowly morphs between the two. Ghosts lets past audio bleed through the current signal. Echoes repeat rhythmically. Imprints leave residual traces. Granular scatters fragments across time. TEXTURE Hiss adds tape noise, from subtle warmth to a roaring floor. Crackle introduces vinyl pops and surface damage. SET IT AND FORGET IT Evolve lets the destruction deepen automatically over time. Pick a duration from 1 to 64 minutes. Walk away. Come back to something completely different. The Randomize button rerolls all destruction parameters instantly. Hit it until something clicks. AUv3 plugin for iOS. Runs in AUM, GarageBand, Logic, and any AUv3 host. Standalone app for iPhone and iPad. From All The Machines.

055U4RY (say it: "ossuary") is an 8-voice polyphonic synthesizer sealed inside a haunted DOS terminal — and, since 1.30, a second plug-in that turns the same machine loose on any audio you feed it. A photographic ASCII skull is the front panel: its jaw hinges open with the amplitude envelope, its eye sockets ignite with the output level, and the whole interface tears, melts and reassembles itself while you play. THE VOICE - 15 synthesis engines: detuned saw/square/triangle unison stacks, sine and sub-oscillators one and two octaves down, two-operator FM, ring modulation and inharmonic partials. Every factory preset is a different engine. - Twin chaotic LFOs that cross-modulate each other's RATE, so pitch and filter drift never repeats. Held notes stay alive and slightly wrong. - A Shepard-Risset layer tuned beneath every note: five windowed partials in an endless downward glissando - the bottomless-pit illusion of classic horror scoring, fused into the oscillator core. - A 19 Hz infrasonic tremolo at the edge of perception. On headphones it is a shiver; on a big system it is pressure. THE CHAIN - State-variable filter, low-pass or band-pass per engine, with resonance that will scream - Sample-rate reducer and bit-depth crusher for terminal-grade lo-fi - Saturating drive stage - GLTCH: a real-time stutter buffer that seizes and re-loops your signal - CRYPT: a damped, pitch-black comb/allpass reverb - GLIDE: exponential portamento up to 1.5 seconds - DOOM: one macro that leans the chaos, the descent and the tremor deeper into the signal PERFORM - 14 knobs, all ASCII, every one audible on every preset - 15 factory presets with per-preset patch memory: your tweaks persist for each preset, and [RESET] restores the factory sound - Two-octave on-screen keyboard with octave transpose and note names - Hardware MIDI in (all sources auto-connect), built-in Bluetooth MIDI pairing, pitch bend, MIDI 2.0 aware - The skull is your meter: jaw = envelope, eyes = level, decay = how hard you push GLTCH 055U4RY FX - THE EFFECT The same app installs a second, separate plug-in. Put it on a drum loop, a guitar, a vocal or a whole mix and run it through the machine: - The full destruction chain as an insert - drive, bit crusher, sample-rate reducer, stutter, filter and the CRYPT reverb - in true stereo - HAUNT: a cross-fed delay whose repeats rot as they decay, with MURK controlling how fast they turn to mud - SYNC: stutters and echoes locked to your host's tempo, 1/16 through 1/1, or free-running - DOOM as an injector: the endless Risset descent and the 19 Hz tremor printed underneath your audio, so anything you feed it gains a bottomless falling drone that was never in the source - Fifteen presets sharing the instrument's names, each a different topology - Wet/dry MIX, output trim, and a skull that reacts to whatever passes through AUv3 + STANDALONE The synth runs standalone with zero setup. Both plug-ins install into your host: AUM, Logic Pro, GarageBand, apeMatrix, WBTRK and any AUv3-compatible DAW, with full parameter automation - "hejluxom: 055U4RY" under instruments, "hejluxom: 055U4RY FX" under effects. One purchase, every platform: iPhone, iPad and Mac. No accounts, no ads, no data collected - your patches never leave the device.
