Muse Sounds are a set of highly sophisticated plugins which provide amazingly realistic playback for MuseScore. You can install them using the Muse Hub application. If you don't have Muse Hub installed you can get it by going to musescore.org and selecting this download button. You can also find a direct link in the description below. Once the Muse Hub is installed you'll see the available Sounds here in the main section and also in the sounds section. Just select the sounds you want and they'll begin downloading right away. Once they're fully downloaded, just launch MuseScore and the new sounds will be assigned by default. Bear in mind that if you've not yet downloaded the sounds for a specific instrument family MuseScore will default to its native sound font Muse Basic instead. Also make sure to try out our new suite of VST effects which you'll find in the effects section. Once downloaded these can be applied in our new mixer panel. Thanks a lot and take care!
