I'm trying to remember the last time I actually saw an arranger for sale in any music store in my local area. Yet they must be selling, as they, Yamaha especially, have been adding new models at a fairly decent pace.
Korg and Yamaha must also be making a decent profit, and IMO, that's a good thing. Otherwise, they truly would die out.
Chas my buddy. It's been awhile. Glad you're not dead
