## 055U4RY Description
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.

### ***** "Honestly really cool"
I make music for horror films and projects. Just downloaded this and I use it for jump scare scenes. This is so awesome. Please make more like this!!
-- Joeethegoat, 2026-09-01

### ***** "Scary Good Glirchery Wizardry"
Really, really good.
-- egoki11a, 2026-08-11

### ****- "Very unique synthesis"
It has some lo fi grunge and doom, but there is more nuances here than most noise makers. Some of the glitches are real sweet and the experimental aspect shines. Seems like there are quick fixes and a responsive dev so cheers to that. This is for the wilder synth type world where you have to fit your self into its features , and not so much looking for  normal synth things. Hails dark wizard

### ***** "🕯️💀Infernal Sounds💀🕯️"
It’s dark and noisy af 🔥 🐀🐀🐀🐀🐀
-- zetarik, 2026-07-30

### ***** "It rules!"
Such a fun synth to play! If the presets are too noisy for you, mess with the settings. I like making it sound just musical enough.
I love the skull guy so much! I try to leave silence long enough for him to close his mouth (I like making the skull look like he’s talking, don’t judge me!).
