USB dance-pad with Rev?

Sorry Richmond but it should not matter about user definable keys or  
not, as the device driver should be monitoring that and then sending  
the appropriate message to the receiving applications..

In theory you can get an external to listen to the messages sent by  
the system, but as demonstrated in my recent external there are issues  
(on the Mac anyways) with the compiled application engine and  
listening for (some?) external events..
