direct sound newbie--question about segments

Hey, I am using directx 8.0 direct sound. I have never programmed sound before and have been browsing some of the articles on this website. I have managed to load to sound files, which I can play simultaneously using the DMUS_SEGF_SECONDARY flag when I call PlaySegmentEx. My question is do I need to load a different segment for every single direct x sound file that I want to be able to play? What is a good way to store/organize in memory all these sound files. I'll put some sample code in here of the application I have at the moment. My thinking for the game is I need a background music that can just play straight through the level and loop, plus sound effects for many actions. Anyway, here is the relevent code that I have for this part. Also when I turn that flag on for the background music, the song goes REALLY slowly. Does this mean that the file is just too big to be a secondary sound file ?



//in GameInit()
CoInitialize(NULL);
    
CoCreateInstance(CLSID_DirectMusicLoader, NULL, 
                 CLSCTX_INPROC, IID_IDirectMusicLoader8,
                 (void**)&g_pLoader);

CoCreateInstance(CLSID_DirectMusicPerformance, NULL,
                 CLSCTX_INPROC, IID_IDirectMusicPerformance8,
                 (void**)&g_pPerformance );
// end of COM and DMusic setup
// init audio
g_pPerformance->InitAudio( 
   NULL,                  // IDirectMusic interface not needed.
   NULL,                  // IDirectSound interface not needed.
   g_hWndMain,                  // Window handle.
   DMUS_APATH_SHARED_STEREOPLUSREVERB,  // Default audiopath type.
   64,                    // Number of performance channels.
   DMUS_AUDIOF_ALL,       // Features on synthesizer.
   NULL                   // Audio parameters; use defaults.
);
// end init audio

CoCreateInstance(CLSID_DirectMusicSegment, NULL, CLSCTX_INPROC,

); // This function has a lot of stuff I did to it, explained below

WCHAR wstrFileName[MAX_PATH] = L"backinussr.mid";

//The above line's filename should be changed to whatever you wish to load
//It can either be mid or wav files. Maybe others, look it up.
 
if (FAILED(g_pLoader->LoadObjectFromFile(
    CLSID_DirectMusicSegment,   // Class identifier.
    IID_IDirectMusicSegment8,   // ID of desired interface.
    wstrFileName,               // Filename.
    (LPVOID*) &g_pSegment)))    // Pointer that receives interface.

    MessageBox( NULL, "Media not found, sample will now quit.", 
                "DMusic Tutorial", MB_OK );
   return 0;
} 

WCHAR wstrFileName2[MAX_PATH] = L"start.wav";
g_pLoader->LoadObjectFromFile(
		CLSID_DirectMusicSegment,
		IID_IDirectMusicSegment8,
		wstrFileName2,
		(LPVOID*) &g_pSegment2);

g_pSegment->Download( g_pPerformance );
g_pSegment2->Download(g_pPerformance);


//In HandleInput
	if (KEYDOWN(VK_LEFT)) {

		g_pPerformance->StopEx(g_pSegment,0,0);


	}

	if (KEYDOWN(VK_RIGHT)) {


g_pPerformance->PlaySegmentEx(
    g_pSegment,  // Segment to play.
    NULL,        // Used for songs; not implemented.
    NULL,        // For transitions. 
    NULL, //  DMUS_SEGF_SECONDARY,           // Flags.
    0,           // Start time; 0 is immediate.
    NULL,        // Pointer that receives segment state.
    NULL,        // Object to stop.
    NULL         // Audiopath, if not default.
); 
	}

	if (KEYDOWN(VK_UP)) {
		g_pPerformance->PlaySegmentEx(
			g_pSegment2, NULL, NULL, 
			DMUS_SEGF_SECONDARY,
			0, NULL,NULL,NULL);
	}

Note that everything works as it is supposed to, just I want to make sure before I actually throw this code into my game that I use the best method or organizing many sounds. Thanks!! Daniel
