Disklavier

The MIDI OUT port is the key, because the MD-BT01 parasitically powers 
itself from the current loop of the host's MIDI OUT port. Wireline MIDI 
is designed such that an OUT port powers an LED connected to the 
receiver's IN port.  (The LEDs are part of opto-isolators that 
electrically protect the two MIDI devices from each other.)   If the 
MD-BT01 is connected to only an IN port, there's no source of power, so 
it won't work.
