Cubase artist render track - how to go back?

I rendered an instr.track and the track muted out like it should. The rendered track shows up under the original but its muted.
But how do I get it to turn on again if I want that? Its a Kont instrument and I wanted to see if it lightened up the cpu load.
Also how do I delete the whole render and go back to original?

Ctrl-Z

how do I do it by menu…?

Can you post a screenshot of the muted track?

I think the moderator knows what I am referring to… ?

Have it your way then. Good luck and good bye.
