Ok pleased that’s working.
You should be able to use Mirage presets too. Perhaps Floe just has somehow lost track of where the Mirage presets are. You can direct it to where the presets are and it should scan them all.
To do that, first try is to click the 3-dots icon near the top-right of Floe, and click ‘Add Mirage Folders’. Open the preset browser to see if presets have appeared.
If still no presets, try adding the Mirage folder manually. Open the preferences panel in Floe this time (gear icon). And then on the Folders tab, add the Mirage preset folder. On Windows, Mirage presets are probably in C:/Users/Public/FrozenPlain/Mirage/Presets or C:/Users/name/Documents/FrozenPlain/Mirage/Presets. On macOS, it would be /Library/Application Support/FrozenPlain/Mirage/Presets. Here’s some more docs about Floe folders: https://floe.audio/docs/key-concepts/folders
Third option would be to download all packages again, and ‘install package’ for each one.
