Parameter

Description

nEventUniqueId

The unique identifier of the MIDI event reported by the MidiDevicesEventReceived event. After calling this method the event is internally deleted from the queue of MIDI events so this unique identifier becomes automatically invalid.

nDeviceUniqueId

Reference that, on return from the method call, will contain the unique identifier (returned by a previous call to the MidiDevices.Open method) of the MIDI input device which generated the event.

nMidiCommand

Reference that, on return from the method call, will contain the number representing the MIDI command value or the MIDI status message (hexadecimal values from F0 to FE)

A detailed summary of available MIDI commands/messages can be found inside the web site of the MIDI Manufacturers Association

nMidiChannel

Reference that, on return from the method call, will contain the number representing the MIDI channel which received the MIDI command.

nMidiData1

Reference that, on return from the method call, will contain the number representing the first parameter related to the MIDI command.

nMidiData2

Reference that, on return from the method call, will contain the number representing the second parameter related to the MIDI command.

nTimeStamp

Reference that, on return from the method call, will contain the time stamp of the event expressed in milliseconds elapsed from the moment in which the MIDI input device was opened through a call to the MidiDevices.Open method.
