Take the time to tweak those styles on the instrument they CAME on, and you get as significant an improvement as porting them to another arranger altogether. Every style is just a launching pad for YOU to make it yours. Expecting it to come OOTB perfect for YOU is a dream. Every last one of us prefers a different sound, and a different amount of space to play over. But I feel that so many Yamaha users like the Roland styles because they have a whole different ATTITUDE towards how much the arranger plays, and how much room is left for you. It isn't necessarily the sounds, it's much more the actual performance.

Just as one player is simpler or busier than another, given exactly the same piece, so different arrangers have the same philosophy. It's not just a question of how MANY parts are playing, it's about how BUSY the part is...

I have always felt like Roland EXPECT you to play the important stuff. All the ACC parts are designed to support you, not take over and do it all for you. Yamaha's and Korg's, OTOH, you can hold down a LH chord and sing over the top, and it's complete! Finding room for your own contribution, given how up-front the ACC is, always strikes me as harder to do on these arrangers.

But port them over from Roland, and you have the best of both worlds. The sounds you like best, with a style 'philosophy' that gives you more room to stretch out and play. For me, personally, the Roland drums are what make me stay on the G70, rather than jump ship but take the styles with me (that and the lack of a 76 from Yamaha). But for those comfortable with the 'sound' they already have, these ports offer up a totally different way to play that the built-ins let you...
