Assetto Ritmo moves to its own domain and its own backend, with English and Chinese from day one.

Hands & fingering
An assistant decides left and right hand and suggests fingering, then writes it back into the score so it is the same everywhere.

Built by someone who lost their scores
Assetto Ritmo started as a personal problem: a score library went offline and the sheet music was gone. So we built the tools we wanted — capture, correct, practise, keep.
