Hi
The presets are files where you can save different configuration of your Xkey.
Only one preset is stored into the Xkey, all parameters are saved into a non volatile memory, that means each time you power off/on your Xkey, the parameters are restored.
There is no possibility with the current firmware to switch between presets without using Xkey plus software, as I mentioned above, one preset is saved into the Xkey.
regards
Jerome
