The library

What a fresh install has

Minuet in G, Ode to Joy and Prelude in C, bars 1 to 19, each public domain with a hand-written arrangement for every level, copied into the library the first time the app opens.

Getting scores in

• ✓Ask Claude Code, which saves into the library.
• ✓Drop a .mid, .musicxml or .mxl into ~/.piano/library and it is imported.
• ✓Open one from the File menu or by dropping it on the window.

Keeping it tidy

• ✓Search by title or composer, and filter by level and tag.
• ✓Correct a title, composer or level; the notes are not touched and the practice history follows.
• ✓Delete sends a piece to the system bin, one at a time or several together.
• ✓Save as MIDI exports the arrangement that is playing.

The recorded piano

The Salamander Grand Piano V3, a Yamaha C5 recorded by Alexander Holm under CC-BY-3.0, cut to four velocity layers and the release samples. The app says how big it is before downloading, the download resumes, every file is checked, and on a machine that cannot download, a copied pack or PIANO_SAMPLE_PACK does the same.
