I have a core and 2 DOUT modules to midify a band organ. When the core is powered up midi note 45 is always on ( LED shows 1|note C_2 Oo) With no midi input connected to the core the note is on, if I connect my midi file player and play a tune it will play all notes just fine BUT midi 45 will always be on. Any suggestions please? I'm stumped.

I assume that the DOUT is connected to the organ so as to operate that key on the organ, in which case check the wiring. You could supply the DOUT with +5V and 0V without the core connected, this would help narrow down where the fault lies.
