"Gee, I would have thought a pricey keyboard like the E-60 would have had EQ for the style parts...glaring omission for sure...of, course, it's a home keyboard, so I guess Roland figured nobody would use them....wrong assumption, obviously"

Maybe Roland didn't want to give "home players" another tool to screw things up..

Personally I can see the individual EQ messing things up for most people...just use a graphic EQ for the room....

Play around with too many things and you will build a system with total mess...Every time you play a different room..it will be different..EQ at the mixer and leave well enough alone..
As for the E-60, I didn't see any need for the part eq's..
