What it does

Bass Dragon writes basslines and 808 patterns in a chosen genre and plays them with its own synth and sampler. It can follow a chord progression you give it, so the generated bass fits the song.

Generation: basslines and 808 patterns in 30 genres, plus a hidden "???" genre that fuses all 30.
Chord detection: drag in your own MIDI progression and it detects the chords, or start from the stock progressions.
Built-in sound: a synth with 200 factory presets and an audio sampler for one-shots and 808s, so any sample can become a playable bass patch.
9 effects: Mangle, Destroy, Bitcrush, Phase, Chorus, Flange, Echo, Space and Verb.
Editing: a piano roll with velocity, quantize and swing controls, plus a preset saver for your own banks.
Routing and export: it can drive external synths and instrument plugins, links with MIDI Wizard to follow its progressions, and exports by drag and drop as MIDI or audio.

It is sold as a one-time purchase on sale, or rent-to-own in eight payments; it has also been part of the Unison Plugin Pass subscription. It comes with free lifetime updates and a 60-day money-back guarantee instead of a demo.

When to use it

Bass Dragon is the pick when you want a bass part written for you that already fits your chords. AltWire found it more immediate than Mixed In Key's Captain bass tools and Pilot, with a stronger sampler for turning any sound into a bass patch. Compared with a synth such as Serum 2 or Vital, it writes the part but offers far less sound design. It works best alongside Unison's MIDI Wizard, which feeds it chord progressions directly.

Best for: 808 and bassline ideas that follow a chord progression, and quick song sketches.
Genres: hip-hop, trap, pop and electronic.
Look elsewhere if: you write your own bass parts and only need a bass sound; Serum 2 or Vital are more useful.
Tip: link it to MIDI Wizard 2 so the bassline follows the generated chords automatically.

What producers say

The one detailed review counted it among the best of Unison's generators.

AltWire (Derek Oswald, 2025) called it "one of my favorites" and the most versatile bass tool it tested, praising the sampler and the link with MIDI Wizard.
Also noted: AltWire found it encourages experimental sound design and listed no specific criticisms.
