The DownloadInstrument method downloads an instrument to the
HRESULT DownloadInstrument( IDirectMusicInstrument* pInstrument, IDirectMusicDownloadedInstrument** ppDownloadedInstrument, DMUS_NOTERANGE* pNoteRanges, DWORD dwNumNoteRanges; );
Pointer to the IDirectMusicInstrument8 interface of the instrument whose data is downloaded.
Address of a variable that receives a pointer to the IDirectMusicDownloadedInstrument8 interface.
Address of an array of DMUS_NOTERANGE structures. Each entry in the array specifies a contiguous range of MIDI note messages to which the instrument must respond. An instrument region is downloaded only if at least one note in that region is specified in the DMUS_NOTERANGE structures.
Number of DMUS_NOTERANGE structures in the array pointed to by pNoteRanges. If this value is set to 0, the pNoteRanges parameter is ignored, and all regions and waveform data for the instrument are downloaded.
If the method succeeds, the return value is S_OK.
If it fails, the method can return one of the error values shown in the following table.
To prevent memory loss, the instrument must be unloaded by calling both IDirectMusicPort8::UnloadInstrument and IDirectMusicDownloadedInstrument8::Release when it is no longer needed.
