This is really an improvement compared to the free Muse Sounds library. The only drawback with this library is the limited articulations every instrument has, but this could be solved with the release of the Strings PRO library or something like that (do not replace it but complement it). The other BIG PROBLEM with this and ANY PAID LIBRARY in MUSESCORE is that when the server gets disconnected (seems to happen when there's an upgrade for Musescore or Museghub for example) or when you get logged out of the app, YOU CAN'T USE ANY PAID LIBRARY, so when you work on a project all the instruments go back to the BASIC MIDI sounds which are awful. Please FIX THIS, it doesn't happen with the free libraries it's very counterproductive. I'll keep posting about this for every library I own until you resolve it.
