Installing musescore4 and musesounds on Ubuntu Studio

Hi there!
What would be the best way to install both musescore 4 and muse sounds in a ubuntu studio environment?

I tried installing musehub, downloaded musesounds, and then using the last nightly release. But in Playback Configuration it doesn’t shows Muse Sounds as an option, just MuseScore basic.

I’ve read somewhere that is best to install ms4 from musehub, but apparently I don’t have that option in musehub.

Thanks a lot for everything!

PS. Sorry if my english is too bad 😛
