All I am saying as a personal opinion and preference I like Yamaha Brass sounds much better then Roland. On the other hand there are a few Roland sounds I liked better in my Roland units also like the Organs & Leslie, & Piano, E.Pianos, also, The guitars it's Yamaha hands down,...but in the end it's the Whole Package I have to contend with on stage as a pro player and for that reason I use a Yamaha S-950 for now.....
