Hi @netjera,
As you suspect the Custom Moods on the Fantasy Player are just a local thing on that device = meant for a quick save of the current state (they are not even particularly safe from getting wiped by the device etc).
For customisation that syncs across all your devices, you’ll do that in the Web Player. MOODs that contain ONLY elements in the already existing SoundSet can be saved in the Web Player without any sub level, but you’ll need a SuperSub for mixing and matching our content from anywhere in the app OR for importing your own samples.
The 2nd and 3rd video on this page: https://syrinscape.com/about-syrinscape/ do a pretty good job of showing what you can do in the Web Player WITHOUT and then WITH a SuperSyrin sub.
Also = Hi!
