STAGE EFFECT CONTROL METHOD AND APPARATUS

摘要

Stage effects (20) are moved by a computer (12) which has stored data indicative of individual stage effects (20) to be moved, their start and finish positions, the speed of movement, and timing and order of movement. The computer (12) controls drive assemblies (24) for moving the effects (20) by a program which, while the program is running, displays on the monitor (16) data concerning movement of the effects (20) and enables the operator to modify at least some of the data previously established.
