How It Works
Install MIDI Agent as a VST3 or AU plugin in your preferred DAW—whether that's Ableton Live, FL Studio, Logic Pro, or any compatible workstation. Start by entering natural language prompts with specific musical directions like key, scale, and harmonic movement to generate initial chord progressions. Drop your existing MIDI into the plugin to create variations and extensions, iterating quickly with 1-2 bar sections until you find the right direction. For spontaneous ideas, use Audio to MIDI to transcribe recordings under 30 seconds, working best with clean, solo instrument performances that you can then edit and develop further.
