Piano

Moldable

v0.1.14·Music

A local-first piano song library with 88-key playback and falling-note practice visualization.

About

A local-first piano practice studio: load songs, watch the notes fall toward a full 88-key keyboard, and play along at your own pace. Everything lives in your workspace, so your library, sounds, and progress stay on your machine.

Highlights

• Falling-note practice view synced to a full 88-key keyboard that highlights active and upcoming notes as the song plays.
• Hands-separate practice: isolate the left or right hand with an adjustable split point, or play the whole piece.
• Variable playback speed (0.1x to 2x) plus scrub, seek, and restart so you can drill tough passages.
• Organize a song library into folders, and follow structured courses with lessons, section-by-section tutorials, and saved completion progress.
• Import your own .mid/.midi files, and create or edit songs note-by-note straight from chat using the app's built-in song RPC.
• Swap instrument sounds with downloadable, high-quality SFZ instrument packs (including the Splendid Grand Piano); per-song sound settings install and select the right voice automatically.
• Fully local: no accounts, no external services, and no API keys — your songs and settings stay in your own workspace.

Install it to turn any MIDI or chat-generated piece into a guided, play-along practice session.
