I don't use the onboard styles. my sd1 is a platform where i can play my loops and samples. the greatest thing about sd1 is that it is the only keyboard i know that have 1 touch selection of 8 sounds and samples. I change sounds a lot. sometimes twice in a single bar, so this is very important to me that the Audya had the same feature.
the worst thing is the limited sampler, and that it have glitches and "hick ups" and I own two sd1s so i know it is the instrument's fault.
my guess is that AUDYA will not be that expensive. it must compete with other keyboards and it can be a little more than the competition but not a lot more.
