Well, Diki, there is such a thing called market research.

Roland has decided there is no need for 76 note arrangers, but they found out about it the hard way...they made them, and they didn't sell.

Why don't you get a job working for Roland or Yamaha, and present your theories to them?

They're bound to listen to a smart lad like yourself, who feels he knows far more than the professionals they have working for them.

Problem solved.
