Make a complete result without personal music.
Sunofriend can generate a small synthetic stem project and run it through the normal automatic conversion. You get the same kinds of MIDI, listening WAV, receipt and ZIP as a first personal project, clearly marked automatic and unreviewed.
1. Ask Codex to run it
Paste this into Codex with local workspace access. A normal ChatGPT conversation can explain the steps, but it cannot quietly run commands or inspect files on your Mac.

Do not clone the repository first. If$sunofriend is not recognised after turn 1, restart Codex once and send turn 2 again.
One fresh output folder
The skill guides Codex to run sunofriend demo --out-dir FRESH. The command creates copyright-safe synthetic stems, then uses the normal automatic MIDI/WAV/ZIP pipeline. It will not overwrite an existing folder.
- no personal audio;
- no optional AI model required;
- local processing;
- automatic, unreviewed output.
2. Hear what the result means
Play the balanced WAV first
Ask Codex to point out the listening WAV and start guide. Then inspect the individual MIDI. The synthetic sources provide timing, song length and level evidence; their audio is not mixed into the MIDI-derived WAV.
Listen to “Out of Place”
This SoundCloud example shows the creative destination beyond the synthetic exercise: musical structure carried into a new MIDI-derived interpretation, not an exact copy of the source.
3. Inspect, then choose your next step
The Aisle at Lidl MIDI pack
The repository also includes a small public pack with individual and full-arrangement Standard MIDI files plus provenance. Drag one into a DAW and choose your own instrument.
Bring authorised top-level WAV stems
