" Sonus Paradisi's first sample set appeared in 2003, later adding to the larger Hauptwerk.cz project.
The Virtual Pipe Organ Project offering historic "virtual" organs from the Czech Republic is named Sonus Paradisi, and sound samples which inspired this composition may be found at the site by clicking on the name itself. For my purposes as composer, I employ these samples through the MyOrgan program (now no longer offered), though more sophisticated players employ the Hauptwerk virtual organ program to play such sound samples.
[ 2 ] The stop sample is named Kryt. Jiri Zurek clarifies the Kryt "is the wooden stopped flue pipe of rather thin scale (mensura). Literally, the Czech word Kryt means the same as German Gedackt, it simply means "covered" (i.e., stopped pipe). So, it is rather generic name of a stop. The Czech Kryt can also be described by the Latin name Copula, Kopula, Koppel, I even saw the spelling "Koputa." It is all the same thing, although the scale may vary from organ to organ giving slightly different timbre."
