SND_SetPlayerTempoRatio 
Syntax
#include <nitro/snd.h>void SND_SetPlayerTempoRatio( int playerNo, int ratio );
Description
Changes the tempo of the sequence being played by the Player specified by playerNo.
The original tempo is multiplied by ratio/256 to get the final tempo value. (The value does not accumulate each time function gets called.)
Note
This function is an ARM7 reserved function. After this function is called, its processing will occur only after the command is issued with the SND_FlushCommand function.
If program execution must be synchronized with process completion, first use the SND_GetCurrentCommandTag function to obtain the command tag immediately after calling this function. Then, after the command is issued, use the command tag and call either the SND_IsFinishedCommandTag or SND_WaitForCommandProc function to confirm that processing has finished or to wait for it to complete.
