If you would like to try NotePerformer in conjunction with Live Stage and Live Space, you might want to look at the custom playback template for NotePerformer that was built by @David_Tee
To make this work you would need to import the Playback Template, then go to the NotePerformer Expression Map, and open up the Expression Map Data section. Check “Apply Stage Template settings”. You will then be able to use both Live Stage and Live Space. (Each instrument will show up on its own channel on the Dorico mixer, so you can also tweak away there.)
