SynthAU/VST3Mac/Win
Partials & Discrepancies
An 8-voice additive polysynth with slot-based motion, up to 128 partials per voice, and semi-controlled divergence between voices.
Unusable Engineering
Creative DSP solutions with simple interfaces and slot sequencers
Unusable Engineering is about building instruments and tools that are simple yet surprising. The lineup spans modelled character effects, science-native tools, and quirky synthesizers and geometry-based effects. Different approaches but with the same goal: expressive and fun tools with clear controls, motion and strong musical sweet spots.

DelayAU/VST3Mac/Win
Geometry Delay
A quick, surprising multi-tap delay where room shape and node motion control the echoes.
ReverbAU/VST3Mac/Win
Geometry Reverb
A hall reverb that uses a room-based abstraction model with 3D orbital modulation.
Auto-panAU/VST3Mac/Win
Binaural Modulator
A room-model auto-pan that can drift into tremolo, Leslie-ish movement, chorus, and more.
SynthAU/VST3Mac/Win
Curves & Membranes
A visual one-oscillator synth built around Bézier wave shaping, orbital motion, and a membrane-style filter model.
Neural VocoderAU/VST3Mac/Win
Synaptic Resonance
A neural vocoder-style effect where input signal excites a 2D simulation that drives a 40-band resonant filter bank.
GranularAU/VST3Mac/Win
Grain Discharge
A cavitation-driven granular effect where fluid simulation events spawn grains from recent input audio history.
DistortionAU/VST3Mac/Win
Cavitation Fractures
A fluid-dynamics processor that can add fracture, erode narrow bands, or pull event-shaped holes from the signal.
DynamicsAU/VST3Mac/Win
Spectral Pressure Chamber
A thermodynamic multiband compressor where spectral pressure drives dynamics and color.
FilterbankAU/VST3Mac/Win
Frequency Guillotine
A 16-band spectral slicer for vocoder-style shaping, stereo motion, and rhythmic spectral manipulation.
ModulationAU/VST3Mac/Win
Ensemble Diffuser
Dual-circuit modulation with stringer-style ensemble motion and hot vintage-inspired phasing.
FilterAU/VST3Mac/Win
Harmonic Dissector
Dual parallel resonant EQ-like filters with slewed slots, clocked stepping, stereo motion, and harmonic edge.
ReverbAU/VST3Mac/Win
Tension Reactor
A physically modelled spring reverb with reactive tank behavior, metallic depth, and unstable tails.
DegradationAU/VST3Mac/Win
Entropy Encoder
A creative codec-decay effect for digital nostalgia and intentional deconstruction and loss.
BundleModelled character tools
Emulated Effects Pack
Five circuit-inspired effects for modulation, filtering, spring space, and controlled digital decay.
BundleScience-native lineup
Scientist Suite
The science-metaphor lineup: Curves & Membranes, Spectral Pressure Chamber, Cavitation Fractures, Grain Discharge, and Synaptic Resonance.
BundleComplete collection
Full Suite v2
All unusable tools in one package, built to surprise, inspire, and keep the creative process moving.

7 August 2026
Preset browsers and slot sequencers across the full lineup
After a deserved vacation, or at least a vacation, I have managed to push most of the plugins forward. Some by small steps, and some by fairly giant leaps.
