JPKeysJam
The song guide that waits
Free · Designed for iPad. Not verified for macOS.
Connect a MIDI keyboard and play a whole song with accompaniment. The song waits until you press the right key. All 133 classical and children's songs are free.
You want to play songs.
Piano apps are everywhere, yet playing a whole song is still hard. While you are hunting for the next key, the song has already moved on.
JPKeysJam waits for you. The song and its accompaniment pause until you press the right key. Connect a MIDI keyboard such as JP-MIDIKey13/25 and play a whole song from start to finish, with accompaniment.
