Drop sheet music here

MusicXML (.musicxml / .xml / .mxl) or MIDI (.mid) — from MuseScore, Flat.io, or any notation app.
Scanned PDFs: convert once with free Audiveris → MusicXML, then drop it here.
Famous songs: search "song name piano musicxml" on musescore.com, download MusicXML or MIDI, drop it in.

📱 On your phone: Android Chrome — open this app, menu → Add to Home screen, then tap 🔵 Bluetooth to link the LUMI. iPhone — Safari has no MIDI: open Maestro inside the free Web MIDI Browser app (native iOS wrapper is on the roadmap).
