pub unsafe static kMIDIPropertySingleRealtimeEntity: &'static CFStringAvailable on crate features
MIDIServices and objc2-core-foundation only.Expand description
device property, integer
Some MIDI interfaces cannot route MIDI realtime messages to individual outputs; they are broadcast. On such devices the inverse is usually also true – incoming realtime messages cannot be identified as originating from any particular source.
When this property is set on a driver device, it signifies the 0-based index of the entity on which incoming realtime messages from the device will appear to have originated from.
