SONAR saves all settings in files, location is OS dependent, but it is under User folder (normally "hidden").
For example, /users/UserName/Application Data/Cakewalk/
You can search your disk for "ACT Data" folder (yes, with space) or for Cakewalk.ini file (it will be in "SONAR <version>" subfolder).
There are the following Control Surface related files:
- "ACT Data" files. genericpluginparams.xml and sonaract.xml keep all ACT mapping. Modifications done in ACT mapping are immediately saved there. They are system wide, independent from project and SONAR version.
- Current configuration for Control Surfaces, inclusive settings within surfaces, are saved in "SONAR <version>"/ctrlsurface.dat file. These settings are SONAR version dependent, but project independent. The file is rebuild by SONAR once removed or corrupted (the configuration will be lost).
- "Shared Presets"/<OID>/. Saved presets for all Surface Plug-ins, each preset is saved in separate file, the file name is the preset name (so easy to find).
It is good idea to have a copy of these files, or the whole "Cakewalk" folder (it is around 5MB only).
