I tried to edit the MML code of a Camille Saint-Saëns Rondo Capriccioso .midi to be similar to the performance of Kaori and Kousei in the anime Your Lie In April. The MML code matched up in 3MLE when previewed but when played in-game, the piano was 1 measure of rest too long. So I deleted the measure of rest and now the code does not match in 3MLE when previewed but matches... in-game... go figure? XD
