An octave up/down toggle switch lets you access the higher octaves on the keyboard. Unlike its ancestors, Chord Organ is compatible with Inter-App Audio and Audiobus so you can record directly into GarageBand, Loopy HD, or any other compatible apps. It also has MIDI support built in for use with your favorite iOS MIDI controllers or sequencers and can be used as a Wi-Fi midi controller. Features: • iOS 8 Ready • Inter-App Audio Support out of the box for use with Garageband and other IAA-enabled apps. • Audiobus Support (requires the Audiobus app, a separate purchase. See http://audiob.us for more info) • Core MIDI enabled • 12 Chord keys for major and minor chords of Bb, F, C, G, D and A. • 29 keys of melody • Octave toggle switch to access even higher octaves
