Installation Paths:
Under the Installation Paths tab you can select the installation path for both the plug-in files (Windows only) and the Sound Data for your XLN products.
The sample libraries for the instrument plugins are called Sound Data. The Sound Data can be installed in a custom location for each of the instrument plugins, this can be done by defining an installation path under the plugin name in the Installation Paths tab.
RC-20 Retro Color and DS-10 Drum Shaper are not listed because they are effect plug-ins and don't contain any sound data.
Under VST 2 plug-ins (64-bit) you can see and set the location of your installed XLN Audio VST 2 plug-ins. The VST 3 versions are by default installed to:
