Generate Music with AI
Stuck staring at a blank MIDI piano roll?
MIDI Agent is an AI-powered chord progression generator and MIDI creation tool that works directly inside your DAW as a VST3, AU, AAX, or Standalone plugin.
Describe the chord progression you want in plain language, set your key, scale, length, and complexity, and get usable MIDI in seconds.
Whether you're writing your first song or your hundredth, MIDI Agent removes the friction between your musical ideas and a finished arrangement - without forcing you to leave your workflow.
Why MIDI Agent
Songwriters often hit the same wall: you have a vibe in your head but translating it into a chord progression takes time, theory knowledge, or both.
MIDI Agent solves this with natural language prompts - describe the harmonic movement you want and let the AI build it.
Already have a progression started?
Drop in your existing MIDI and generate continuations or variations that stay musically coherent.
You spend less time hunting for the right chords and more time actually writing songs.

Adjust the length and complexity parameters, then generate.
Drop the resulting MIDI onto a track, listen back, and iterate.
Use the MIDI continuation feature to extend sections once you find a direction that works.
