       Two major problems for constructors are often the provision of keyboards 
     with the necessary contacts and couplers with the multitude of switching 
     and wiring necessary. This system overcomes both these problems. The 
     infra-red PCB system is simply mounted below the keyboards. The output 
     from each keyboard is in midi format and feeds into a PIC based decoder 
     which caters for all normal couplers.
     
     Further detail is in course of preparation.
