No. Nothing was pre-recorded and no musicians were off-stage
unless there was an understudy on who didn't play a particular instrument. In that case, there would be someone in the wings playing whatever was missing, and unless you were in the front on the very very far sides, you wouldn't have been able to see him or her. For example, I saw a performance when Angel Desai was sick, and Katrina Yaukey went on for Marta. She didn't play violin, so one of the understudies who did play violin covered those parts from the wings. Other than a situation like that, no, there were never any "ghost" musicians. The drum set was way in the back, in the corner of stage right. It was kind of difficult to see sometimes because of the lighting, but it was there.
And I echo the recommendations to watch the Original Cast Recording documentary if you like the show.
A work of art is an invitation to love.
