MM_MIM_DATA message
The MM_MIM_DATA message is sent to a window when a complete MIDI message is received by a MIDI input device.
MM_MIM_DATA
wParam = (WPARAM) hInput
lParam = (LPARAM) (DWORD) lMidiMessage
Parameters
-
hInput
-
Handle to the MIDI input device that received the MIDI message.
-
lMidiMessage
-
MIDI message that was received. The message is packed into a doubleword value as follows:
Requirement Value Description High word High-order byte Not used. Low-order byte Contains a second byte of MIDI data (when needed). Low word High-order byte Contains the first byte of MIDI data (when needed). Low-order byte Contains the MIDI status. The two MIDI data bytes are optional, depending on the MIDI status byte.
Return Value
This message does not return a value.
Remarks
MIDI messages received from a MIDI input port have running status disabled; each message is expanded to include the MIDI status byte.
This message is not sent when a MIDI system-exclusive message is received. No time stamp is available with this message. For time-stamped input data, you must use the messages that are sent to callback functions.
