There is nothing like having your hands on a keyboard. Or an acoustic piano. Those are the things you can't really replace.

To some degree. I think that I've always been very much of a chordal person. The chords are the foundation of everything. Some of Yes' stuff is very linear, albeit complex, but it's single-line melodic stuff. So I kind of had to wear a different cap working with Yes. It's not so much chord-based.

Styx has their own style of music, and I think that's justifiable, the same way that Asia and Yes have had - Yes particularly has a unique style that seems to have transcended all styles of music for 43 years.

I think that Yes' music is kind of on its own out there, and it goes through different chapters, and that involves different people. I don't think it's a case of 'any year is better than any other.' They can all co-exist quite comfortably.

With NOAH, you can create some stunning, yet original soundscapes. Therefore, as a performance tool, it really comes into its own because you can make one single performance which has a lot of detail.

I've always been fascinated with the juxtaposition of technology in music, not only in recording, but in the keyboard. It's amazing the way you can apply technology to an art form.
