Lyria 3 Music Generation for GarageBand

MIDI Agent brings the power of AI MIDI generation directly into your GarageBand workflow, letting you create melodies, chord progressions, and full compositions using natural language prompts — no music theory expertise required. Whether you're building tracks from scratch or extending an existing idea, MIDI Agent's Audio to MIDI transcription, MIDI continuation, and customizable parameters like key, scale, length, and complexity give GarageBand producers a genuinely intelligent creative partner. For users who want access to the Lyria 3 Music Generator for GarageBand, the MIDI Agent Pro subscription unlocks exclusive AI providers including Google AI Lyria 3.

GarageBand producers often hit creative walls — a melody that goes nowhere, a chord progression that feels repetitive, or a recorded riff you can't easily edit. MIDI Agent addresses these specific pain points by letting you drop in existing MIDI files to generate variations, convert audio recordings to editable MIDI, and craft new musical ideas through descriptive text prompts. Installed as an AU plugin directly in GarageBand, it fits naturally into your existing session without disrupting your creative process.

Getting started is straightforward: install the AU plugin by placing it in /Library/Audio/Plug-Ins/Components and restarting GarageBand. Once loaded, open MIDI Agent on a track and enter a natural language prompt describing your melody, rhythm, or harmonic idea. Adjust key, scale, length, and complexity to match your project. To use Google AI Lyria 3, activate a MIDI Agent Pro subscription for managed API access. For audio conversion, import a clean recording under 30 seconds and let the Audio to MIDI engine transcribe it for immediate editing.
