Hi FransN

I have not heard the Wing so cannot say how the sound compares.

The demos on You Tube are of the early prototype, the production models have the sound and styles set up by Music Store, as it will be competing with all the other arrangers that they sell. (Yamaha, Korg etc.)

I believe demos are currently being produced, so hopefully it will not be too long before they become available.

Best way is to contact your local Wersi Service agent http://www.wersi-promotion.nl/ who will probably have more details.

Regards

Bill
