I need to download each online available Preset separately. Is there a way to download all at the same Time ?
If you click the 'Playlists' button in the top right of your screenshot, you will be able to download multiple presets in playlists, rather than clicking each patch individually.
You can also download the Extended Library package from your My ROLI account.
Just sign in to your My ROLI page, and under your products registration, look for "Equator Extended Library," and click the download icon for your operating system.
Once the installer has finished downloading, open it from your downloads folder to install the additional presets.
Hope that helps,
