Arpeggionome (the name is a mashup of the terms “arpeggio” and “metronome”) was released as a cool music-making device for the iPad. It could not only make cool music by itself, but it could act as a MIDI controller for other iOS MIDI devices, external devices and instruments, as well as computer recoding software. In December of 2012, Arpeggionome Pro was released, which had additional features and capability in the MIDI department. It also has a redesigned interface from the original Arpeggionome. It was updated to version 1.1 yesterday (June 23rd, 2013). Recently, Arpeggionome was released for the iPhone as well.
Arpeggionome Pro is $19.99 in the iTunes store. Arpeggionome for iPhone is $2.99.
