Thank you guys for feedback, I'll forward these infos to the relevant people so that they will hopefully produce demo videos in the studio (but it will take some time so a bit more patience is required )

Chris A: yes it was definitively bad timing I hope too we can meet in Frankfurt. (but I don't have infos if the company will be there so I make no promises :-) ).

aliev: AFAIK first keyboards will be shipped in about 3 months. They will be available through european distributors too so you don't need to get them from the US.
Regarding styles and presets, don't worry the guy that is making them has worked for a few major keyboard brands so he knows what he does. But as said final judgement can only be made when high quality mp3s will be available or better trying out the real keyboard.

cheers,
Benno
