Celestia sits on a balcony on the other side of the machine from you, to intervene in case something goes catastrophically wrong. You stand near a hand-wheel that controls the transmission, in front of a big sliding bar that indicates the transmission’s current setting. A paddle with one red and one green side rests on top of a notepad on the control box. Behind you sits a guest you requested Twilight bring; a musician with absolute pitch.  The gray earth pony holds ready a cello, and a violin sits on a table beside her.
