MidiFlow Piano

Practice your MIDI pieces with MidiFlow Piano on iPhone. Import a MIDI file, connect a Bluetooth MIDI keyboard, and follow the music as sheet notation or falling notes.

Free to download:
• Practice at your own pace in Triggered mode, which waits for the highlighted notes.
• Use Real-time mode with a three-second count-in and pause or resume where you left off.
• Switch between sheet music and piano roll while keeping your place.
• Start with the included classical pieces and see feedback on the notes you play.
• Add freely licensed pieces from the Free Classical Pieces catalog.
• Set the tempo from 40% to 150%.
• Import one MIDI file of your own.

MidiFlow Unlimited, a one-time in-app purchase:
• Import as many MIDI files of your own as you like and keep them with titles, artists and difficulty levels.
• Loop any bars: drag two handles that snap to the barlines, in the piano roll or in the sheet music.
• Let the speed trainer start a loop slowly and speed up after every clean round, up to your target tempo.
• Practice one hand at a time; the other hand stays visible but dimmed.
• Add a metronome click that follows the time signature.
