Unisynth is a generative synthesizer plugin from Unison, producing a new sound from a chosen genre and sound type — bass, chords, leads, pads, plucks, or 808s — across 32 genres plus a genre-blending “???” option. Each generated patch runs through four oscillators independently switchable between Analog, Wavetable, Sampler, and Resonator modes, with 25 built-in effects and a full Advanced Mode for parameter-level editing after generation. It’s sold as a one-time purchase covering Unisynth alone, or through a monthly subscription bundling access to Unison’s full eight-plugin catalog.

Key Takeaway

The core value is genre-and-type-driven sound generation across four independently switchable oscillator modes, with a full effects and editing layer built in for finishing a patch afterward. The one-time purchase and the monthly Plugin Pass subscription aren’t equivalent options — the subscription grants access only while payments continue, rather than permanent ownership of Unisynth specifically.

Two Choices, One Generated Sound

Unisynth generates a sound from two selections — a genre and a sound type, such as bass, chords, leads, pads, plucks, or 808s — rather than starting from a blank synth or a browsable preset library. Pressing generate produces a new sound built from that genre-and-type combination each time, so repeating the same selections doesn’t return the same identical result twice.

That generation draws from a library of genre-specific wavetables, samples, parameters, and effects settings, along with complete synth presets built around patterns found in commercially successful tracks within each genre — described by Unison as an “AI Sound Engine” recombining that curated content on each generation rather than pulling from a fixed, browsable preset list.

Four Oscillators, Four Synthesis Methods

Unisynth runs four oscillators, and each one switches independently between Analog, Wavetable, Sampler, and Resonator modes rather than all four sharing one fixed oscillator type. That per-oscillator mode selection means a single patch can combine an analog-modeled oscillator, a wavetable oscillator, a sample-based oscillator, and a resonator-based oscillator simultaneously, rather than committing the whole instrument to one synthesis method.

Mixing oscillator types this way is what lets a generated patch combine different sonic characters in one sound — an analog oscillator’s warmth layered against a sampler oscillator’s real-world texture, for instance — rather than needing to bounce and layer separate synth instances to get the same blend.

One Genre That Ignores the Rules

Alongside the 32 named genres, a separate genre labeled “???” combines elements from all 32 into generated sounds rather than staying confined to any single genre’s conventions. Selecting it produces a sound that draws on cross-genre combinations rather than following one genre’s specific frameworks the way the other 32 options do.

That option exists specifically for building a sound that doesn’t fit neatly into one established genre bucket — a starting point assembled from multiple genres at once rather than a hybrid a producer would otherwise build manually by blending two separate generated patches together.

Finishing Happens Inside the Instance

A generated sound loads ready to use as-is, or opens into Advanced Mode for full parameter-level editing across the oscillators and signal chain. Twenty-five built-in effects — including distortion, reverb, stereo-widening tools, EQ, and compression — sit inside the plugin itself, covering enough of a finishing chain that a generated sound can go from raw patch to a more finished tone without leaving Unisynth for outboard plugins.

Because the 25 effects live inside the same instance as the generation engine, adjusting them after generating a sound stays part of the same editing pass rather than requiring a bounce to audio and a separate plugin chain — a mix bus’s own EQ, compression, and space still typically layer on top of whatever finishing Unisynth’s internal FX already did to the raw generated patch.

Own It or Access It

Unisynth sells as a one-time purchase covering the plugin alone, with lifetime access and free updates included, or through Unison’s Plugin Pass, a $19.99-per-month subscription covering all eight Unison plugins together rather than Unisynth specifically, with a 7-day free trial before billing starts.

The one-time purchase and the subscription aren’t the same product at different prices — the one-time path owns Unisynth specifically forever, while the subscription grants access to the whole Unison catalog only for as long as the monthly payments continue, and canceling the subscription ends access to Unisynth along with the other seven plugins rather than leaving the one plugin usable on its own.
