int MusHandleSetReverb(musHandle handle, int reverb);
It sets the reverb offset value for the channels associated with the specified sound handle. The reverb offset is used as a base value for the reverb settings defined in the sound data, and the sound data's settings are scaled based on the remaining possible settings (128 - reverb).
The handle must be a sound handle returned by MusStartSong(), MusStartSongFromMarker(), MusStartEffect(), or MusStartEffect2(). If a handle of zero is supplied, this function will always return zero.
The reverb value should be within the range of 0 to 0x7F (127). The default reverb offset for all channels is 0. This value is used in the following manner to calculate the channel's reverb level:
channelreverb = reverb+(((128-reverb)*datareverb)>>7)
Number of channels which have been changed.
void ReverbFromDepth(unsigned long handle, int depth)
{
/* depth in range 0-32767 */
MusHandleSetReverb(handle, depth>>8);
