A process of staging a live or pre-recorded performance that follows a schedule is disclosed. The performance involves electronic and mechanical media that are computer controlled, preferably so as to create a virtual reality of events. When an action that is not normal to the schedule occurs, the timing, speed, or sequence of one or more media activities are adjusted to compensate for the action so that the action does not adversely affect the continuity and totality of the performance to the audience. Computer hardware and software embodiments include a script of a scheduled performance and a control program that steps through the script while allowing for flexibility and adaptation of the performance in response to an action that is not normal to the schedule. A control interface to the sensory stimuli device may be provided to sensory stimuli associated with the performance by the control program.
