Sounds like a watered down version of XV5080 synth sounds played back with cotton stuck in my ears. Typical Roland to utilize sounds from their high end devices, resample them at lower rates, and put them in a cheaper unit using really poor AD/DA's. At least it's not expensive so I'm sure it will sell well.
Oh ok I wish I didn't bother posting this! I think it sounds fine to me.
Btw does the Audya & Korg contain chillout / ambient styles? The last Korg I owned was a PA1X and I didn't recall it having any back then. Great keyboard though.
