The MIM_DATA message is sent to a MIDI input callback function when a MIDI message is received by a MIDI input device.
MIM_DATA dwParam1 = dwMidiMessage dwParam2 = dwTimestamp
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.
Time that the message was received by the input device driver. The time stamp is specified in milliseconds, beginning at zero when the midiInStart function was called.
This message does not return a value.
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.
