A system for communication among audio-related devices in an audio system includes a performance equipment manager that communicates with audio-related devices to monitor and control changeable parameters of a corresponding audio-related device. Each of the audio-related devices includes an audio node structure having components that are representative of the functionality of the respective audio-related device. Some of the components are representative of changeable parameters in the audio-related device. The performance equipment manager is configured to be selectively subscribed to one or more of the changeable parameters so that when a predefined condition occurs, the audio-related device is configured to automatically provide the current value of the changeable parameter(s) to the performance equipment manager.
