Tony,
I think that there is way too much reverb in many songs. I did like Sleepwalk, but have a feeling that they somehow "sampled" the Rhodes intro from the Larry Carlton rendition. The Rhodes was, however, very good.
I hate to repeat myself, but I still do think that the sound is not as clean as other keyboards, like the Yamahas (Tyros or 9000) or the Rolands (VA7 or 76). So I would say that the Genesys is maybe good for gigging, but not so good for a home studio, sound-wise.
I did like the Bossa Nova style in One Note Samba, but I think that the drum fills in Sleepwalk are too heavy and inappropriate.
Well, you asked for an opinion, you got it...
