Watch a quick demonstration of MIDI Agent's capabilities and see how it can transform your music production workflow.

Generate MIDI with AI

Use MIDI Agent when a melody, chord progression, bassline, or drum pattern is working but needs somewhere to go. Drop the MIDI into the VST3, AU, or AAX plugin, describe how the part should develop, and generate an editable extension, variation, response, transition, or next section. The Standalone app provides the same workflow without opening a DAW.

Why it fits

Why MIDI Agent

Because the result stays editable MIDI, you can combine it with the original phrase, rewrite notes, change voicings, alter the rhythm, or route it to another instrument. Set the key, scale, length, and complexity to match the role of the section, then keep only the material that supports your arrangement.

AI MIDI Generators vs Audio Generators

Audio tools can sketch ideas quickly, but MIDI keeps the notes editable in your DAW. Compare the workflow before choosing an AI music tool.

Audio Generators

Create finished tracks that are useful as references, but difficult to reshape at the musical data level.

  • Fixed audio output that cannot be changed note by note
  • Locked to generated sounds and instruments
  • Usually web-first instead of DAW-native

Examples: Suno, Udio, Soundraw, Mubert

MIDI Generators

Produce raw musical data you can edit, arrange, voice, and route through your own instruments.

  • Connect your ChatGPT account
  • Editable notes, timing, velocities, and expression
  • Route the same idea to any instrument in your session
  • Keep AI-generated ideas inside your DAW workflow

Examples: MIDI Agent, AIVA, Magenta Studio
