The "Live Sound" of the Audya makes that keyboard an "enigma".

It's an enigma because it has so much promise and potential, but lacks of support, reliability, 3rd party styles / voices / programs, and company loyalty.

If the Audya was sold by Yamaha, I would probably own one. However, my personal experience with both the Audya and Ketron was horrible. The keyboard does not feel like it is finished. It lacks usable software tools for creating new styles based on their wave technology. Yes, many users will say they have a style creator, but I liken it to programming in assembly code. Everything Ketron tries to do seems 3rd rate from the manuals to the support network to software releases to software bugs.

Buying a Ketron, from my experiences only, is a huge risk. But the paradox is the wonderful LIVE sound!
