I doubt seriously that there is a single young player in the audience other than maybe someone that is actually into this kind of stuff! Hard to kill arranger sales to a missing demographic!

Yamaha's Techno Expansion Pak could do wonders if marketed right, though.

I have said for a long time that the arranger manufacturers should sell TWO versions of each arranger. One packed with oldies styles and one packed with modern ones. And next to no crossover. Then sell the missing styles as an expansion pak to the few from each demographic that might want to play outside their age range.

Then you put the modern ones in stores that sell modern gear, and the oldies ones in Mom and Pop piano and organ stores, and Bob's yer uncle! Sales go through the roof!
