Instructions transmitted via the Musical Instrument Digital Interface (MIDI) protocol, specifically designed for controlling show-related equipment, allow synchronization and automation across various performance elements. These messages can trigger lighting cues, audio playback, video projection, and other stage effects. For example, a single command could initiate a specific lighting configuration and start a pre-recorded soundtrack simultaneously.
The ability to remotely manipulate diverse equipment offers considerable advantages in live performance and presentation environments. It streamlines operations, reduces the need for manual intervention, and enhances the overall precision and impact of a show. This technology evolved to address the growing complexity of theatrical productions and the increasing integration of digital media into live events, leading to more sophisticated and cohesive performances.
