Samples can be exported together with the corresponding program or layer as VST presets, or on their own. In both cases, you use the “Export Samples…” option on the Program Tree context menu. For VST presets, the corresponding dialog has additional preset options.
•To export a VST preset, select the program or layer in the Program Tree. On the context menu, open the Import/Export submenu, and select “Export Samples…”.
