I have been simply selecting brass patches in place of strings or piano for selected styles where it will work. But you don't have control over the individual brass patches. Not the greatest but it's fast an easy. RB will probably give me more options and I will revisit downloading midi tracks and use the extended patches of the Ketron. I think the extra effort will be worth it once I'm past the initial learning curve. I have watched a couple of YouTube videos on RB and I should have the s/w upgrade soon.
