Where do I get a MIDI file?
Most music programs can save one. In MuseScore (free) choose File → Export → MIDI. Sibelius, Finale, Dorico, GarageBand and Logic can export MIDI too. Many websites also share MIDI files; please only use music you are allowed to use.
What does it do with my file?
It finds the part that carries the tune, takes one note at a time (the top note of any chord), tidies the rhythm into notes a violinist can read, works out the key, and picks a string and finger for every note: 1st position and open strings first, with as few shifts as possible. The other parts become the backing, and chord names are worked out from them.
Is my MIDI file uploaded anywhere?
No. The file is read inside your web browser and never leaves your device. Songs you open are kept in your browser on this device, so you can come back to them, and you can remove them at any time.
The bar lines or rhythm look wrong. What can I change?
Under “Arrangement settings”, try “Up-beat” if the music starts before the first strong beat, “Time” if the time signature is wrong, and “Rhythm: Quavers (simplest)” if the rhythm looks too busy. Files made in a notation program work best; recordings of live playing are harder to tidy up.
Can I change a fingering?
Yes. Step to the note, type a different string and finger under “Fingering for this note” and press Change. Teachers can also edit the whole piece in the code box. Changes are saved on this device.
How do I share my fingering with a student?
Press “💾 Export song” above the music. It saves one small file with the MIDI, your settings (key signature, bars and so on) and your fingering changes. Send it by email or message; your student opens this page, presses “📥 Import a song file” and gets exactly your version. “Back up all my songs” saves every song in one file, to move them to another computer or tablet.
