The midiOutReset function turns off all notes on all MIDI channels for the specified MIDI output device.
MMRESULT midiOutReset(
HMIDIOUT hmo
);
Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following:
Value | Description |
---|---|
MMSYSERR_INVALHANDLE | The specified device handle is invalid. |
Any pending system-exclusive or stream output buffers are returned to the callback function and the MHDR_DONE flag is set in the dwFlags member of the MIDIHDR structure.
Terminating a system-exclusive message without sending an EOX (end-of-exclusive) byte might cause problems for the receiving device. The midiOutReset function does not send an EOX byte when it terminates a system-exclusive message — applications are responsible for doing this.
To turn off all notes, a note-off message for each note in each channel is sent. In addition, the sustain controller is turned off for each channel.
