Further to GrahamG's reply -
You could do it using a MidiBoutique mdec decoder board.
These are easier to use, though more expensive, than MIDI-Box units, and I
have successfully used one in the context of Couplers and Stops, getting
real LED's to echo the state of the on-screen elements. But I haven't any
experience with virtual illuminated pistons ...
