1. A distributed stage lighting system with adjustable tempo, comprising:
- a plurality of controlled stage lights, distributed at a plurality of locations; and
a controller for said stage lights, said controller connected to said stage lights and including a system clock that maintains an indication of time;
said controller including a commanding element which sends commands to said plurality of lights at predetermined times that are set by the system clock in the controller and a time varying element which varies said indication of time in a way that causes said predetermined times of operation of said plurality of lights to be varied relative to one another.

Abstract
A time synchronizing unit operates to synchronize lamps with various indicia. Each of these indicia are tied to a system clock. The system clock is normally incremented at specified intervals, e.g., every 4 milliseconds. The system is to be synchronized with a stage lighting production such as a song. If the tempo of the song changes, the amount of time between interrupts changes. Hence the time when things occur will be varied as the system clock changes. This enables varying the time when the things occur without actually changing the program: the time is bent to accommodate the new tempo of the program.

14. A distributed processing varying system, comprising:
-
first and second distributed processing objects, each including lighting devices which are remotely controllable, said first and second distributed objects each including a processor which is commanded at certain times to carry out certain operations; a lighting controller, connected to said first and second distributed processing objects, said controller operating to provide commands to carry out said operations to said first and second distributed objects, said controller comprising a controlling system which commands operations to be carried out at determined times, a time changing element, receiving an indication of a new time synchronizing indicia, and a time synchronizing device, responsive to said time changing element, for synchronizing said operations with the predetermined times, said time synchronizing unit being changed by said time changing unit to thereby change the times when operations occur in both said first and second distributed processing units. - View Dependent Claims (15, 16, 17, 18)

19. A method of changing a timing of a system, comprising:
-
synchronizing a plurality of lighting events occuring at different separated locations with times that are set in a system clock; determining if said system clock needs to be modified to cause said lighting events to occur at a desired tempo; and modifying said system clock if modification is necessary. - View Dependent Claims (20, 21, 22, 23, 24)

25. A distributed lighting system, comprising:
-
a plurality of computer controlled lights, each being remotely controllable; a controller, having controls which control said plurality of computer controlled lights, and having an input representing information in MIDI format from at least one musical instrument, said controller including an element which synchronizes an internal timer with a temp of music represented by said information, and automatically changes controlling said lights according to said internal timer.
