PCO Chart Editing with LLM

One of my new favorite use cases for Claude Code with the PCO API is basic file editing. It's really good at editing chord charts, piano charts, lead sheets, and audio, and crosswalking all of them, so I make a change in one place and it changes everywhere, down to Ableton Live cues and section markers.

My pianist and organist always complain about the page turns with this coda, so I just asked it to paginate it out. The page duplication cheat in MusicStand works, but you lose your place on which time through you're on.

It saves a new file name with and renames the old one. Afterward, it opens Planning Center in browser. I confirm it looks good, and get it to delete the old one, or wait a week if I'm squeamish. It's one of the least destructive applications, since it always saves a local copy.

It saves a ton of work and opens up options you never would have considered because it's too much work otherwise.
