| Type Name | IMidiMessageReceivedEventSource |
| Type | WinRT Explicit Interface |
| IDL | IMidiMessageReceivedEventSource.idl |
Interface which contains the event definition used by any class which raises the MessageReceived event. This is defined in an interface so that message processing plugins and the MidiEndpointConnection type can be used interchangeably in an event handler.
The MessageReceived event is raised synchronously, and needs to be handled quickly and efficiently by the calling application.
Applications are typically much faster than devices at handling messages. However, failing to drain the incoming message queue fast enough can result in transmission errors. With MIDI 2.0 there is no upper performance limit on devices, and USB 3 and Network MIDI devices, among others, are capable of transmitting a large number of messages in a very short period of time.
If you need to do long-running processing of incoming messages, add them to your own incoming queue and have them processed by another application thread.
