Disklavier

That device is cleverly designed in that it appears to be powered by the 
current loop of the MIDI OUT port to which it's connected. I suppose 
that means it would not work on a device equipped with only MIDI IN, 
since MIDI IN ports do not supply power (the connected external device 
drives an optocoupler).
