This is a somewhat cynical view of the arranger as an instrument though... Let's get rid of all those features that the 'average' home user doesn't use.

Might as well start with those pesky black notes, too, as I am sure most of those 'quit when they were nine' wannabe's mostly play in C... Think of the money the arranger manufacturers could save (and the complication for the user!), and of course, how much lighter it could be

The perfect arranger.... for morons!
