Currents & Nostalgia
A 6-voice virtual analog synth built around two circuit-modelled saw-core oscillators, classic filters and two independent slot systems for musical movement.
Unusable Engineering is about building instruments and tools that are simple yet surprising. The lineup spans modelled character effects, science-native tools, unique 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. The unusable plugins don't use plugin managers or call home functions.
A 6-voice virtual analog synth built around two circuit-modelled saw-core oscillators, classic filters and two independent slot systems for musical movement.
An 8-voice additive polysynth with slot-based motion, up to 128 partials per voice, and semi-controlled divergence between voices.
A visual one-oscillator synth built around Bézier and node wave shaping, orbital motion, and a membrane-style filter model.
A transistor-inspired fuzz with self-oscillation, pitch quantization, side-chain-controlled mix, and an 8-slot sequencer.
A four-quadrant multiplier with a bezier oscillator, pitch following, one-shot shaping, and an 8-slot waveform sequencer.
A quick, surprising multi-tap delay where room shape and node motion control the echoes.
A hall reverb that uses a room-based abstraction model with 3D orbital modulation.
A room-model auto-pan that can drift into tremolo, Leslie-ish movement, chorus, and more.
A neural vocoder-style effect where input signal excites a 2D simulation that drives a 40-band resonant filter bank.
A cavitation-driven granular effect where fluid simulation events spawn grains from recent input audio history.
A fluid-dynamics processor that can add fracture, erode narrow bands, or pull event-shaped holes from the signal.
A thermodynamic multiband effect where spectral pressure drives dynamics, saturation, and resonance.
A 16-band spectral slicer for vocoder-style shaping, stereo motion, and rhythmic spectral manipulation.
Dual-circuit modulation with stringer-style ensemble motion and hot vintage-inspired phasing.
Dual parallel resonant EQ-like filters with slewed slots, clocked stepping, stereo motion, and harmonic edge.
A physically modelled spring reverb with reactive tank behavior, metallic depth, and unstable tails.
A creative codec-decay effect for digital nostalgia and intentional deconstruction and loss.
Six circuit-inspired effects for fuzz, modulation, filtering, spring space, and controlled digital decay.
The science-metaphor lineup: Curves & Membranes, Quadrant Modulator, Spectral Pressure Chamber, Cavitation Fractures, Grain Discharge, and Synaptic Resonance.
Two synthesizers and all fourteen effects in one package. Currents & Nostalgia is sold separately.
Curves & Membranes v1.5.0 adds Filter Bank and Pressure modes, expanded orbital modulation, four-voice glide and keytracking, whole-patch randomization, new presets, and a naming shortcut now available across the lineup.
Partials & Discrepancies v1.5.0 adds detune, oscillator smear, ring modulation, a new self-oscillating filter, glide, a refreshed interface and 42 new factory presets.
Resize-scale persistence across every plugin, creative additions to six effects, synth workflow updates, and a look at Currents & Nostalgia.
