These songs in the shop are originally created for use with this app. Currently, the number of songs is small, but we will gradually increase it. * Some MIDI files may not be played well because of too many parts in the file. We assume a midi file contains five to six parts of SATB and accompaniment piano + some more parts. And we recommend MIDI file of format type 1, although you may still use type 0. Interchangeablitiy: We have tested MIDI files generated by applications belows and some unknown apps.
