Problems with downloads?

Sample set contain tremmed samples of whole stops. In the package there are two ODFs (organ definition files). One is dedicated to users, who have enabled wind supply model. Second one is for the others. The only difference between these two ODFs is tremulant engaging mechanism. With wind model enabled there is smooth crossfade between untremmed and tremmed sound. Without it, it just retriggers notes, which is less realistic. It was impossible to include those two behaviours in one ODF, so choose the right one for you and delete or do not install the other one.

To use the sample set, you need to extract downloaded file and open the file with .organ extension. If you can't extract downloaded file, please try to use 7-zip (for Windows).
Important: For best realism please uncheck option Release sample scaling, which is located on the first tab of Audio/Midi Settings.

GrandOrgue versions of sample sets usually comes in two versions, which vary in size of graphic interface. Sample set images are created prospectively to meet the requirements of displays with high resolutions. Legacy versions of GrandOrgue, contrary to Hauptwerk, had very poor image scaling algorithms, so resized graphic interface become uglier and illegible. Still, the size of the window doesn't fit to display resolution after first load of the sample set, so if it exceeds you need to resize it somehow. Window size should be saved for next organ loads. That's why I decided to make a version(s), which has smaller size (usually 70% of original), which should fit most of the modern displays.

The interface of every sample set for Hauptwerk contains tabs. Their counterpart in GrandOrgue are panels, which are accesible from main menu. This is the place where you find other pages of sample set, if they were provided.
