IDirectMusicInstrument8::GetPatch

Retrieves the patch number for the instrument. The patch number is an address composed of the MSB and LSB bank selects and the MIDI patch (program change) number. An optional flag bit indicates that the instrument is a drum, rather than a melodic instrument.

HRESULT GetPatch(
  DWORD* pdwPatch
);

Parameters

pdwPatch
Address of a variable that receives the patch number.

Return Values

If the method succeeds, the return value is S_OK.

If it fails, the method can return one of the following error values:

DMUS_E_NOT_INIT
E_POINTER

Remarks

The patch number returned at pdwPatch describes the full patch address, including the MIDI parameters for MSB and LSB bank select. In addition, the high bit is set if the instrument is specifically a drum kit, intended to be played on MIDI channel 10. This is a special tag for DLS Level 1, because DLS Level 1 always plays drums on MIDI channel 10. For more information, see MIDI Channel Messages.
