How can I backup my (user-) presets?
The presets you create (user presets) while working with a plug-in are stored in XML-files named like "preset_xyz.xml", where xyz is the name of the preset.
Windows:
This files can be found in your "My Documents" folder under MolecularBytes\<plugin-name>\userprograms\.
For atomicreverb on Window-10 for example: C:\Users\<username>\My Documents\MolecularBytes\AtomicReverb\userprograms\
You can include this file in your backup program. If you are creating backups of your "My Documents" folder anyway, you don't need to do anything - your presets are saved automatically.
Mac:
The files can be found in your user folder under ~<user>/Library/Audio/Presets/MolecularBytes/...
There's a folder for each plug-in containing the XML files of the user-presets.
