CarolPlayMidi enables you to perform favorite Christmas carols or classic hymns in four-part harmony, most of the time playing with just two fingers. You can play expressively, controlling tempo, volume, and articulation. Note: CarolPlayMidi is a "midi controller." It works by sending chord and note information to a synthesizer app. The synthesizer app then creates the sound. There are many synthesizer apps which can be used to create the sound.
