[edit] Loading and playing tracker modules with FMod

FMod makes it very simple to play tracker modules:

The Fmod system is initalized with a call to FSOUND_Init()

#include <stdio.h>
#include <conio.h>
#include <time.h>
#include "fmod.h"
 
void Pause(clock_t Delay);
 
int main(int argc, char* argv[])
 {
  int Index;
 
  FMUSIC_MODULE *Song;
 
  // Initalize the Fmod System at 44Khz and 32 channels
   if(FSOUND_Init(44100, 32, 0))
    {
     printf("FMOD Init OK\n");
    }
   else
    {
     printf("FMOD Init Failed!\n");
     return 0;
    }

We load our tracker mod with FMUSIC_LoadSong()

// Load our tracker module
  Song=FMUSIC_LoadSong("distant.mod");
 
   if(Song==NULL)
    {
     printf("Load song failed!\n");
     return 0;
    }
   else
    {
     printf("Load song OK, Press any key to stop playback\n");
    }

FMUSIC_PlaySong() and FMUSIC_StopSong() control the playback, here I've used FMUSIC_SetMasterVolume to fade out the track.

// Play the tune
  FMUSIC_PlaySong(Song);
 
  // Wait for a keypress
  getch();
 
  printf("Fading...\n");
 
  // Fade the song out nicely
   for(Index=256;Index>0;Index--)
    {
     FMUSIC_SetMasterVolume(Song,Index);
     Pause(1);
    }
  // Stop playback
  FMUSIC_StopSong(Song);

Finally a call to FSOUND_Close() cleans up Fmod.

// Shut down the FMod system
  FSOUND_Close();
 
  return 0;
 }

This function provides a short delay to allow the music to fade slowly

// Delay execution for a few milliseconds
void Pause(clock_t Delay)
{
 clock_t ExitTime;
 
 ExitTime=Delay + clock();
 
  while( ExitTime > clock() ) ;
}

Note: You'll need to link in the fmod library, "fmodvc.lib" or whatever is appropriate for your compiler.
