"MiditinaXL is a WiFi-based wireless 48-button English Concertina MIDI control surface for the iPad.
The button layout is identical to the real instrument and, and the built-in note guide makes it easy to learn to play!
To play, simply touch the buttons. Buttons light up when playing.
Multiple buttons may be touched at the same time to play chords.
You can slide between the buttons.
Touch the '?' icon to show the note names for each button.
Touch the MIDI connector icon to show the MIDI controls.
You may select the volume, MIDI channel, attack velocity, and transposition (+/- 12 semitones).
MiditinaXL doesn't produce any sound on it own, it is designed for controlling hardware or software VST-style MIDI synthesizers via a WiFi connection to a Windows or Mac OS X based computer.
Multiple iPads can run MiditinaXL on the same wireless network, each sending messages on its own set of MIDI channels to the hardware or software synthesizer."
