What’s New Now
As of June 25, 2026, Unusable Engineering adds four new plugins to the lineup for macOS and Windows and brings the full line to 14 plugins.
The main release is Partials & Discrepancies, a new 8-voice additive polysynth built around a faster and more visual way of working with partials. Instead of presenting additive synthesis as a long technical list, it is built around a control model that makes it easier to shape, offset, warp, and animate groups of partials quickly.
Alongside it, the launch also adds Binaural Modulator, Geometry Delay, and Geometry Reverb, expanding the line further into spatial and movement-based effects.
Launch highlights
Partials & Discrepancies
Synthesizer
An 8-voice additive polysynth with up to 128 sine partials per voice.
The core idea was not just to make another additive synth, but to make one that feels faster to work with. Instead of presenting partials as a long technical list, the synth is built around a visual control model where groups of partials can be shaped, offset, warped, and pushed into disagreement in more immediate ways.
That makes it possible to move quickly between harmonic, dissonant, animated, and unstable sounds without losing the overview. The point is not to make additive synthesis feel simplified, but to make it feel playable.

Binaural Modulator
Effect
A spatial modulation effect built around a room model with a fixed listener and moving sound-source nodes.
At its simplest it can work as an auto-pan, but the room model, node movement, Doppler, and stereo linking make it capable of tremolo, rotating-speaker style movement, rough chorus behavior, and more animated spatial misuse.

Geometry Delay
Effect
A multi-tap delay built around a simple room abstraction.
Walls, floor, and ceiling act as taps, and moving the play-and-listen node shifts several delay times at once. Because the node can also orbit in 3D, Geometry Delay can smear, wobble, and bend in pitch through Doppler-like motion while staying quick to set up.

Geometry Reverb
Effect
A hall reverb using the same room-based abstraction model and 3D orbital modulation approach as Geometry Delay.
Geometry Reverb came out of a failed reverb experiment, later paired with the geometry control model. It is free for paying customers, new or old, and available from the account page together with its license and other downloads.

What Makes The Line Distinct
- Unusual internal engines: many plugins are built around simulation-based or non-standard systems where behavior is the key feature.
- Direct interfaces: no extra pages or hidden layers. What you see is what you get.
- Limited by choice: these are focused tools, not stretched to cover every possible use case.
- Built for exploration: immediate controls and visual feedback leave room for happy accidents.

Company background
I started building these plugins because I wanted music software to feel rewarding again.
A lot of software is impressive in ways I can respect, but not always enjoyable to use. Once things turn into pages, hidden functions, and long option trees, I often end up stepping through presets instead of interacting with the tool.
What I missed was the feeling of focused hardware in the studio: a clear purpose, a clear surface, visual feedback, and a sense that something interesting can happen when you push it.
That is where Unusable Engineering comes from. These are focused tools with unusual internal behavior, direct controls, and limitations chosen on purpose. The point is not to cover every possible task. It is to make tools that are quick to grasp, inspiring to use, and capable of leading somewhere interesting.
Unusable Engineering is a Danish developer of software instruments and effects. The plugins are built around unusual internal engines, direct interfaces, and focused design choices intended to keep the creative process playful, clear, and rewarding.
