Tony...no offense taken...actually in my duo i probably use about 75 total styles from both the yamaha and korg...what i like about the 2 is the difference in styles (the korg love the live sound) the yamaha have more a CD quality to it...so between the 2 they give me a lot of options....when i said, i have over 600 styles to choose from...when i pratice alone i often use styles i don't use in my duo...just to break up my practice session and feel for the tune...kind of like being an artist with a lot of shades in paint colors....stevec
