055U4RY

An 8-voice horror synthesizer inside a haunted terminal: chaotic twin LFOs, an endless Shepard descent, pitch-black reverb — and an ASCII skull that plays back at you.

055U4RY (say it: "ossuary") is an 8-voice polyphonic synthesizer sealed 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
