The manual has referenced a setting in
Preferences > File > Folder Locations since the introduction of the ProChannel. To my knowledge, there has never been a preferences entry dedicated to Prochannel presets. The location is controlled by the
ProChannelStripPresetFolder registry key in
HKEY_CURRENT_USER\Software\Cakewalk Music Software\SONAR Producer\X3\UserPaths Either directly modify the registry or use mklink to create a directory join to the actual location.
For example, if the Prochannel presets are located in "C:\Cakewalk Content\SONAR X3 Producer\ProChannel Presets" and need to be relocated to "D:\CW\Presets\PC":
1) Move the presets to "D:\CW\Presets\PC"
2) Delete "C:\Cakewalk Content\SONAR X3 Producer\ProChannel Presets"
3) Open the cmd prompt and issue the command:
mklink /j "C:\Cakewalk Content\SONAR X3 Producer\ProChannel Presets" "D:\CW\Presets\PC"
