I know exactly and in detail how digital sound creation works.... so again : Where does the AD-conversion take place in these keyboards? (There is no AD conversion at all in a Tyros, except only while making audio recordings)

Sill no answer who of you really touched/played both machines? (no one)

Why do you guys feel the need to always comment/compare instruments of other brands? Whenever other members comment equipment that you choose your reactions are touchy.
Wersi and Mediastation (ordinary PC boards running Windos or Linux) are way overpriced, sound way outdated, and need (external) VST's to make it produce a decent sound.

Mediastation did not make it and Wersi is heading for the next bankrupt. Please wake up and realize the Yamaha stuff sounds much better and more musical than the 'open arrangers'..... and yes : Out of the box!
Stop commenting machines other people like/choose using only YT demo's.

As far as I know Ensnareyou did only write about his 'superiour equipment' *My arranger") with no limitations at all. Please show us what you are capable of in a YT demo. That might impress us?
