HI Bachus

What you say is correct, but you have forgotten one vitally important problem, and it has nothing to do with software, (As you say that is easy to implement) it’s the fact that there are 3 separate teams at work here (Piano, Synth & Arranger) which would need to be combined, and this would become extremely problematical as jobs would be duplicated, different philosophy’s would not go well together (Which could mean some of the top designers going elsewhere) and redundancy’s would have to be made, this is further complicated as the design teams in big companies are spread worldwide, so it would take considerable restructuring (And financial resources) to achieve, then there is the problem that profits would fall as they would only be selling one type of instrument rather than 3, so don’t expect any changes in the near future.
As technology advances the instruments will automatically be combined into a new single venture (Any name suggestions) with one new design team, (This will be because of consumer demand (Basically the young get older and the oldies die off) as styles change) however it will probably be some time yet as the move will be generational. (Whichever way you look at it, the instruments we play today are a dying (As are their players) but it is always difficult to predict how much time they have left)
