On the Prospectum website, the organ has now been moved to the category "Masterpieces".
http://www.prospectum.com/en/start.htmThere are photos, screen shots, and information of what you will get with the sample set.
I wonder whether you can virtually open the Brustwerk doors and get a it to sound a little louder?
Whether you like this type of organ (it's virtually almost a Schnitger) and these dry acoustics of this small church or not, I have to comment that the sound demos seem very realistic.
Let's just wait and see what the asking price is as this is is apparently a non-for-profit volunteer project, which is highly commendable and amazing in and of itself. In that sense we can't complain that it took so long to get it out.
