MM_MIM_DATA

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 of 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:

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 Values

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.
