055U4RY VST3 — free horror synthesizer for macOS & Windows

THE VOICE

15 synthesis engines: detuned unison stacks, sub-oscillators, two-operator FM, ring modulation, inharmonic partials
Twin chaotic LFOs cross-modulating each other's rate — drift that never repeats
An endless Shepard–Risset descent tuned beneath every note
19 Hz infrasonic tremolo at the edge of perception

THE CHAIN

State-variable filter (LP/BP) with screaming resonance
Sample-rate reducer · bitcrusher · saturating drive
GLTCH: real-time stutter buffer
CRYPT: pitch-black damped reverb
GLIDE: exponential portamento

PERFORM

14 ASCII knobs, all audible on every preset, all automatable
15 presets with per-preset patch memory + factory reset
MIDI from your host, pitch bend, three-octave on-screen keyboard with HOLD
The same engine as the iOS / Mac app, sample for sample

INSTALL

Mac

Unzip, then move 055U4RY.vst3 to ~/Library/Audio/Plug-Ins/VST3 (your user Library; in Finder hold ⌥ and open the Go menu). Restart your DAW and rescan plug-ins. The build is signed and notarized, so macOS asks nothing.

Windows

Unzip, then move the 055U4RY.vst3 folder to C:\Program Files\Common Files\VST3. Restart your DAW and rescan plug-ins.

Standalone

Both zips also carry a standalone version (055U4RY.app / 055U4RY.exe) that plays without a DAW, from your MIDI keyboard or the on-screen keys.

If it haunts you, support the work — buy the app, with the FX plug-in, for iPhone, iPad and Mac: 055U4RY on the App Store.

FAQ

Windows says "Windows protected your PC".

That is SmartScreen meeting the standalone 055U4RY.exe for the first time; the plug-in itself loads silently in your DAW. Click “More info”, then “Run anyway”.

Where is the FX plug-in?

The VST3 is the instrument only. The 055U4RY FX insert effect ships with the iOS / Mac app.

Which hosts?

Any VST3 host: Ableton Live, Reaper, Cubase, Studio One, Bitwig, FL Studio, Renoise… Logic Pro and GarageBand load AudioUnits, not VST3 — use the App Store version there.

The screen is glitching.

Yes. It is supposed to.
