Hello Domenik
Nice to know you still keeping in touch, I thought you might have left for good.
The demo itself shows what can be achieved with an open type keyboard, and I would suggest that you go through some of the other older demos on your site and clear them out, as they do not show off the Mediastation to its full potential.
As far as I am aware you still do not have a presence in the UK, and as yet never featured at any of the Festivals, which I think would benefit you, by allowing people to compare your product with others, and thus see and hear the benefits of an open keyboard, I know Wersi always go down well at the Festivals, and that is why I play one of their OAS instruments. (I have previously used both Hardware and Software based systems)
I hope you consider some of the above, and continue to develop the Mediastation.
Regards

Bill
