Infusion Systems I-CubeX USB-microDig MIDI implementation uses the following data format for all system exclusive messages:

Byte	Description

125 (7Dh)	Manufacturer ID
{DEV}	Device ID
{CMD}	Command or Message ID
[BODY]	Main Data
247 (F7h)	End of System Exclusive

Manufacturer ID

The manufacturer identifies the manufacturer of a MIDI device. Infusion Systems uses the number 125 (7Dh). Infusion Systems does not own the manufacturer ID 125 (7Dh). This ID is usually reserved for general educational and/or research equipment. Please ensure that you do not have any devices with manufacturer ID 125 (7Dh) in your MIDI chain.

Device ID

This ID identifies a specific USB-microDig in setups with multiple USB-microDigs. This setting should remain 0 for use of the USB-microDig in stand-alone mode. Host mode allows for device IDs other than 0.

Command and Message IDs and [Main Data]

The Command and Message IDs and [Main Data] form the protocol for communication with the USB-microDig. The protocol consists of commands that are sent to the USB-microDig and messages that are sent by the USB-microDig. The Command and Message ID description and [Main Data] formats are described starting on the next page.
