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.
Update to support iOS 9.
Also improves support for the remote media player control (e.g. from lock screen).
Ratings and Reviews
Excellent app for learning choral music
The app is easy to use. You have to search the Internet for free midi files or you can buy them from cyberbass. To load them, you just email them to yourself and when you click on the attachment the learn my part icon pops up and you just click to add it to the app. The app isolates the parts and gives you the ability to put in a loop for difficult parts and slow them down until you learn them. Sometimes you have to search around for different versions of the midi files to find one that works, but once you do you can work on the music from your IPad or IPhone any time. My only complaint is that the app does not seem to turn horizontal when I am using the IPad, so I can't keep it in my keyboard. An update to fix this would be appreciated.
Still loving this app, several years later.
I had a question, emailed the developer, and he responded very quickly, and was extremely helpful.
Original review, march 2014:
I can easily download midi files off my choral website. I like how you can highlight any given line, and manipulate the tempo.
Great for practice at home
This app is great if you don't have a piano at home or can't play one. You find modi files for your piece on the internet and download them on your ipad on this app. You can then highlight or isolate your part and slow it down to go over the hard parts. You can loop parts, but I haven't figured that out yet.
With Family Sharing set up, up to six family members can use this app.
