Piruz Labs Releases Three Plugins: Two Free Synths & The Guilt Device Emotional Degradation Unit

Piruz Labs, a one-person audio software lab in Vilnius, has released three plugins for macOS and Windows: two of them completely free.

Thrilled Groove

Thrilled Groove (Free) is an 80s horror-funk mini synth built around six one-knob mood macros: Groove, Fright, Neon, Punch, Space and Age. Together they dial in instant 80s horror-funk: Carpenter fog, Thriller-style basslines, neon arpeggios and gated-era textures. Factory presets cover Bass, Stab, Lead, Pad, Bell and FX.

Thrilled Groove is my love letter to the sound of the 1980s, and I wanted everyone to have it for free, the way that music was given to me.

Synthimatic

Synthimatic (FREE) is a visual subtractive synth that draws the waveform and spectrum in real time as you shape the sound, with a built-in hint system that teaches what each section does while you play. Two oscillators plus noise, a resonant filter, separate amp and filter envelopes, a tempo-syncable LFO, and factory presets that double as lessons.

Most synths ask you to turn knobs in the dark. I wanted one that showed me.

The Guilt Device

The Guilt Device ($39 one-time, 14-day fully working free trial) is an "emotional degradation unit": it does not repeat your sound, it remembers it incorrectly. A single macro Guilt knob drives reverse delay, granular smear, pitch drift, dark-chamber ambience, decay and collapse together, with six modes (Confession, Buried, Aftermath, Relapse, The Weight, Absolution), A/B states and oversampling up to 4x. Built for dark ambient, industrial, doom, post-rock and cinematic scoring.
