The Yamaha is the hands down winner in country & western styles. Solton is second.
The Big band styles are equally great in Korg, Yamaha & Techniques I think.
The Latin styles on the Solton have a slight edge, but the flash styles on the Yammy are great.
Techno & Underground etc - no clue what they are supposed to sound like, so I lump them into the disco vein - Yamaha, Korg & Solton were my favorites there. In that order.
Sorry to say, but of all the stock styles - Roland has been the bottom of my list for a few years now. The piano & string sounds were always good, but the styles put me to sleep.
After playing this PSR9k for a few months I'm starting to like the simplicity of the styles more & more. It actually makes them MORE versitile for me. I've said before - "I'd rather play with Ringo Star then Steve Gadd, anyday" I want SOLID rhythm - not a soloist.
Last night I played the opening of a new Lexus dealership in Trenton NJ - there were lot's of high income folks strutting around, and in the main showroom there was a jazz trio - digital piano, upright bass & drums. No vocals. Very smooth and classy sound. I was at the other end of the dealership in the service area, where the food was, so I muted all the "gingerbread" parts in the arranger except for bas & drums and I emulated the same basic style as the band out front - the sound was VERY well received, and after an hour or so, I was really getting into the "openness" of the arrangement. I still played a lot of manual bass but I was experimenting with using better, more complex chord voicings and syncapations with my piano hand, so I put the bass on "auto" to free up my brain a little. I played more jazz standards that night then I have in a while! It was a great excercise in "less is more". I highly recommend it to all of you. Turn OFF some of the arranger parts, and fill in the arrangment YOURself! You'll have more fun - sound fresher, and get paid
exactly THE SAME !!!!!!!! THE SAME !!!!!!!
(there's a moral there)
