M2-105-UM_v1-01_Property_Exchange_Foundational_Resources.pdf
This specification defines three Foundational Resources: DeviceInfo, ChannelList, and JSONSchema.

M2-106-UM_v1-01_Property_Exchange_Mode_Resources.pdf
This specification defines two Resources, ModeList and CurrentMode. If a Property Exchange Device has Modes, then it should support the ModeList Resource and CurrentMode Resource.

M2-101-UM_v1-1_MIDI-CI_Specification
MIDI-CI defines an architecture that allows Devices with bidirectional communication to agree to use extended MIDI capabilities beyond those defined in MIDI 1.0, while carefully protecting backward compatibility. MIDI-CI features “fall back” mechanisms so that if a Device does not support new features MIDI continues to work as defined by MIDI 1.0. Goals of MIDI-CI design:
Fully backward compatible: supports continued MIDI 1.0 functionality for any Devices that do not recognize extended MIDI features enabled by MIDI-CI.

1. Allow easy configuration between MIDI-CI Devices.
2. Sender can know the capabilities of a Receiver.
3. Sender and Receiver can negotiate auto-configuration details
4. Define method for negotiating choice of Protocol between Devices.
5. Define method for using Profiles.
6. Define method for Discovering, Getting, and Setting a wide range of Device Properties. 

M2-103-UM_v1-1_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.

M2-107-UM_v1-01_Property_Exchange_ProgramList_Resource.pdf
This specification defines the ProgramList Resource. If a Property Exchange Device has Programs selectable by Bank Select and Program Change messages, then it should support the ProgramList Resource.

M2-108-UM_v1-01_Channel_Resources.pdf

This document defines three Property Exchange Resources: ChannelMode, BasicChannelRx, and BasicChannelTx. These Resources are used to Get and Set information related to the choice of MIDI Channels which are actively in use by a Device.

There is an additional Property Resource defined to address the use of MIDI Channels, ChannelList, which is not defined in this document but is in MIDI-CI Property Exchange Foundational Resources: DeviceInfo, ChannelList, JSONSchema. Devices which have complex usage of MIDI Channels should also implement the ChannelList Resource.

M2-109-UM_v1-01_LocalOn_Resource.pdf

This document defines the LocalOn Resource which uses Property Exchange to Get and Set the "Local On/Off" setting of a Property Exchange Device.

M2-110-UM_v1-01_MaxSysex8Streams_Resource.pdf

This document defines the MaxSysex8Streams Resource which uses Property Exchange to discover how many simultaneous System Exclusive 8 messages are supported by a Device when using the MIDI 2.0 Protocol.

M2-111-UM_v1-0_Get_and_Set_Device_State.pdf

The Property Exchange Resources described in this document allow for an Initiator to send or receive Device State, or in other words, to capture a snapshot which might be sent back to the Device at a later time. The primary goal of this application of Property Exchange is to GET the current memory of a MIDI Device. This allows a Digital Audio Workstation (DAW) or other Initiator to store the State of a Responder Device between closing and opening of a project. Before a DAW closes a project, it performs the GET inquiry and the target Device sends a REPLY with all data necessary to restore the current State at a later time. When the DAW reopens a project, the target Device can be restored to its prior State by sending an Inquiry: Set Property Data Message.

M2-112-UM_v1-0_ExternalSync_Resource.pdf

This document defines the ExternalSync Resource. If a Property Exchange Device has a clock which is able to synchronize to external MIDI sync messages, then the Device should support the ExternalSync Resource.
