Description

055U4RY (say it: "ossuary") is an 8-voice polyphonic AUv3 synthesizer and an AUv3 FX, sealed together inside a haunted DOS terminal. 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

AUv3 SYNTH + AUv3 FX + STANDALONE

Runs standalone with zero setup, and installs as an AUv3 instrument and an AUv3 FX in your host: AUM, Logic Pro, GarageBand, apeMatrix, WBTRK and any AUv3-compatible DAW, with full parameter automation.
