Hey! Here is a little video showcasing how the Sublevel system is implemented on Republic RT.
A pretty unprepared and not very professional demo. Still, happy that all these buttons and input boxes are finally working as intended.
I do my recordings, normally, pretty late at night. Expect some mumbling or nonsense, from my side 
.
I hope you like the feature and the way the levels can be handled.
Best!
