The console of the organ features stopswitches which slide between two vertically positioned states: their upper position indicates that the stop is off, the lower means that the stop is engaged. There are various “pages” in the Hauptwerk™ displays containing close-up images of the stops. If you manipulate the stops or controls in one page, their on/off status will be synchronized with the other pages as well.
On the control pages of the virtual instrument some stop switches are pale red coloured, instead of white. This indicates that those stops are not available, since they have not yet been built in the actual instrument.
Note: All stop switches of the 1st manual are disabled (which is indicated by their red color), since in the actual instrument, which is planned to be a five manual symphonic organ, none of the stops of the first divsion have been built yet.
