Learn My Part is designed primarily to help choir members learn their individual voice parts. There are some sample MIDI files pre-loaded but you can add your own files to the app through iTunes file sharing, or opening midi file attachments from Mail or Safari on the iPhone (detailed instructions on how to do this are in the built-in help). The app provides various ways to play MIDI files, giving the user the ability to play just their part on its own, their part highlighted with others playing quietly, or just the other parts and not theirs. Or they can do any custom mix of the tracks they like. It allows the playback speed to be adjusted slower or faster, sub-sections to be marked and repeated over and over again, and transposition. The user can choose to play each track using piano or organ sound. It can also display PDF Scores, allowing a score to be viewed while listening to a MIDI file being played back.

Chorus Lesson is a kind of MIDI player, build for the use of personal lesson of chorus. The app allows you set mute, soloed, volume, panning and instrument for each part. You may check your melody line by enabling only your part. Then, sing hearing the overall flow and sound of other parts. You may also change the playing speed, you can practice your part carefully at your suitable tempo. You can play standard MIDI files with this app. In addition, we have a Song Data Shop in this app. You can purchase and download song data in-app purchase. 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.
