Montuno... read up about how you will have a very limited ability to load new styles into the S950. I think you will find yourself disappointed. At best, you will only be able to get a tiny few more in there, and you won't be able to load them in and out on the gig. If and when Yamaha get around to making them. They include NO tools for you to be able to do this for yourself - in fact, these styles are as protected and proprietary as the old arrangers that you couldn't make styles for, and the only new styles you ever got where what the manufacturer ONLY ever sold you...

Yamaha need to do pretty much a total makeover of this feature for it to be of any PRACTICAL use.
