AI MIDI Generator for GarageBand

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. Whether 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, continue 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 real-time AI-powered MIDI generation without leaving your DAW.

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 continuation 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 instantly, then refine the results directly in GarageBand.

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 MIDI in real-time 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 short 1-2 bar sections 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.
