Things I would use AI for in music production:
1. Generating track layouts (add tracks + empty audio/midi clips throughout)
2. Generating MIDI sequences
3. Generating Serum patches
4. Extracting stems from existing audio
5. Automating common workflows (eg sidechaining)
6. Semantic search of sample library
That being said, I don't think I want a full agentic workflow for vibe-producing. Point solutions seems like a better fit for me, personally.
