Piano
A desktop piano built to be driven from Claude Code. Its plugin brings an MCP server that writes, checks and keeps scores, then opens the app to play them: the notes fall onto the keyboard, and practice mode waits for you on MIDI or the computer keys, loops a bar and says how each one went.

All 110 entries →- PI111 · 55a9c5cPiano has no public page, README or LICENSE, so nobody finds it and the MIT claim points at no file
Piano has a public site at /piano/ on freewilly's model, its facts generated from the repo, deployed with the sample pack, plus LICENSE, README and CONTRIBUTING (design recorded in
site/README.md). - PI110 · 6e4672fno installer survives the release workflow, so v0.1.0 cannot be published
All three installers now package, install and pass the association check in CI: Linux names its executable, Windows lets go of .piano, macOS reads split claims.
- PI109 · 595940fA chosen option is told from the ones beside it by the weight of its text, which reads as no difference
A chosen option carries the accent and is measured against its neighbours in both themes, which also caught the light accent failing its own text contrast.
- PI108 · dafae33Open recent still offers a deleted piece, and the system's own list still offers one at the path it has moved from
A deleted piece leaves Open recent with it, and the system's own list is rebuilt from ours whenever ours changes, so neither offers a file that has gone.
- PI107 · 047a05cDeleting or retitling from chat skips the bin and leaves the practice records behind, where the panel does neither
With no window a delete says it cannot be undone before doing it, and a correction leaves a note the app applies to the records next launch.
- PI106 · 4da6187Open recent names a piece by the title it had when it was opened, so a corrected one is listed under its old name
A corrected piece is offered from Open recent under what it is called now, at the path it moved to, without waiting to be opened again.
- PI105 · 27ca9bcTidying a library that grew by the batch means opening, confirming and closing one row at a time
Rows can be picked in the panel and then deleted or tagged together, with one question asked of the whole set and one sentence about how it went.
- PI104 · a9dcd39Claude Code can write a score into the library but never remove one, nor correct what one says without rewriting it
correct_score changes what a score says about itself and delete_score takes one out, both through the library module the window writes with.
