ca24 Global Parameter Control SysEx Message.pdf
This proposal allows the editing of global parameters in a device using Universal Real-Time System Exclusive messages. These global parameters may include effects parameters, system control parameters, or other non-channel-specific parameters. Because there may be more than one instance of an object containing global parameters in the same device, and these multiple instances may have similar parameters or even contain additional objects in an object hierarchy, an optional mechanism is provided for uniquely identifying the “slot” within the object hierarchy containing the global parameters.

When coupled with specific recommended practices for parameters and values, these messages will provide common parameter editing among a variety of playback devices.
