This illustrates exactly why this 'feature' is a total boondoggle. I doubt any of us here would use more than 50% of these styles, if that.

So, let's think about this. Rather than add 25 new drum KITS, using the sounds recorded for these styles, and then ALL of your Yamaha styles would sound this good, Yamaha give you closed, uneditable audio styles that you can't add to in any practical sense. And so few styles that, out of 400+ styles in the arranger, you'll get maybe 10 you might use.

What the heck are they smoking over there?
