Generative MIDI is a MIDI effect and standalone application for creating rhythmic and melodic patterns with algorithmic generators. It is aimed at musicians who want to shape MIDI patterns and route them to an instrument in a compatible DAW, particularly Mac users seeking a free tool. Its documented engines include Euclidean rhythm generation, Markov chains, L-systems, cellular automata, probabilistic generation, and stochastic processes such as Brownian motion, Perlin noise, drunk-walk, and the Lorenz attractor. The project is open source under the MIT license, with a perpetual license model.

Pattern shaping goes beyond choosing a generator. Users can set tempo, pattern density, scale, root note, velocity, gate length, legato, and note retrigger behavior. Swing and timing/velocity humanization provide further control over the output. MIDI can be routed across channels 1–16, and DAW parameter automation is supported. Real-time playback-position and pattern visualization help expose what is being generated. These capabilities make the plugin more suited to exploratory composition and repeatable pattern creation than to producing finished audio on its own.

The documented macOS builds are AU and VST3, with Logic Pro, Ableton Live, Reaper, and GarageBand listed as compatible DAWs. Although the project overview mentions iOS/iPadOS AUv3, it says that target is not store-ready; the documented release/build instructions are for macOS. The product describes algorithmic and stochastic generation rather than machine-learning features, so it is a weaker fit for buyers specifically seeking AI music plugins. Free, open-source access may suit solo musicians and small teams comfortable with an algorithmic MIDI effect; choose another tool if machine-learning generation or a documented non-macOS release is essential.

Generative MIDI pros and cons

  • Where it wins
    • Generates patterns with Euclidean, Markov-chain, and other algorithmic methods
    • Includes scale, root-note, swing, and timing/velocity humanization controls
    • Supports MIDI routing, DAW parameter automation, and pattern visualization
  • Where it doesn't
    • The documented macOS release/build instructions limit platform fit
    • Its documented generation is algorithmic, not machine-learning based
    • Support channels are docs and community
