I did over a month of research going to several music stores looking for a main keyboard. I've owned an XP-50 in addition, and the W7 is a much better synth--ricer, fuller sound, and MUCH MUCH MUCH easier to use. It's a creative tool... just wish it had more support on the internet. If you're interested in starting some sort of mailing list/discussion group, or if you have any questions about this synth, feel free to mail me at jmandell@students.wisc.edu. I could even create a W7 web page if anyone is interested.
Comments About the Sounds:
Wonderful electronic sounds, high quality samples. And I'm picky
