M2-103-UM_v1-2_Common_Rules_for_MIDI-CI_Property_Exchange.
Property Exchange is a set of MIDI-CI messages used to access a wide range of properties in MIDI devices. The exchange of properties takes place between a MIDI-CI Initiator and a MIDI-CI Responder.
This Common Rules for Property Exchange document provides a complement to the MIDI-CI specification by defining details of the Property Exchange mechanism and rules for the data payload in MIDI-CI Property Exchange messages. Further Property Exchange specifications define schemas and various data payloads that use the rules in MIDI-CI and this document to achieve specific tasks.
