Generate MIDI in GarageBand with AI

MIDI Agent is an AI MIDI generator for GarageBand that transforms how you create music by turning natural language prompts into melodies, chord progressions, and full compositions directly in your workflow. If you're sketching initial ideas or developing complete arrangements, this AU plugin eliminates writer's block and accelerates your creative process. Generate customizable MIDI with specific parameters like key, scale, length, and complexity, extend existing MIDI files to create variations while maintaining musical coherence, or convert audio samples to MIDI with intelligent transcription. MIDI Agent integrates seamlessly into GarageBand, giving you AI MIDI generation without leaving your DAW.

Why it fits

Why GarageBand

GarageBand producers often struggle with writer's block, time-consuming MIDI programming, and extracting musical ideas from recordings. MIDI Agent solves these challenges by letting you generate MIDI from text descriptions, eliminating hours of manual note placement. The audio to MIDI transcription feature extracts musical ideas from your recorded performances, while the MIDI extension capability helps you develop existing ideas into complete sections. Instead of staring at empty piano rolls, you can describe what you want and generate it, then refine the results directly in GarageBand.

How it works

From prompt to MIDI notes

Getting started with MIDI Agent in GarageBand is straightforward: install the AU plugin in /Library/Audio/Plug-Ins/Components and restart GarageBand. Once loaded, you can generate editable MIDI by entering natural language prompts that describe note patterns, rhythms, melodic movement, and harmonic elements. For best results, give specific musical directions rather than vague style references, generate the section length you need and iterate quickly, then extend once you find the right direction. The plugin works with your own API keys or a MIDI Agent Pro subscription for managed service access.

  1. Step 1

    Describe the musical part, constraints, and production role you need.

  2. Step 2

    Generate a short MIDI idea and audition it through your own instruments.

  3. Step 3

    Edit, extend, vary, or regenerate the strongest result inside your session.

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
