The synth responds to velocity changes. How is responds is program dependent. The velocity layers are defined in the sfz file(s) associated with the program. CSC does not expose its program elements making it difficult to analyze the program details. It is possible to see this information in DPro and Rapture, the two synths playback modules used in CSC. The program names are the same between the CSC, Dpro and Rapture so it is possible to use DPro and Rapture to see which sfz file(s) make up the program. If the program is from a DSF expansion pack, sometimes it is possible to figure out the sfz file(s) use but it is guesswork because they only exist as CSC programs.
