It is nearly ten years since I had the pleasure of addressing this Association, and during that period the present and future uses of electrical methods of music production have resolved themselves into reasonably well-defined fields. Firstly we have the commercial instruments, nearly all of the organ type, which have separated themselves into different ways of doing the same thing. Little progress has been made in the design of these instruments, for no new methods have been discovered, and thus we find instruments for serious music and entertainment making use of superior methods of manufacture and the increasing improvement in electronic components. The result is, to the user, a better made instrument and one which will stand in tune for long periods—certainly far longer than any pipe organ. Advances in methods of tropicalising parts have also improved the sales abroad.
