void SND_SetTrackPanRange( int playerNo, u32 trackBitMask, int panRange );
playerNo |
The Player number. Takes a value between 0 and 15. |
trackBitMask |
This is the track bit mask. It designates which track to use. |
panRange |
The pan range. Takes a value between 0 and 127. |
Changes the track pan range for the sequence playing on the player specified by the player number playerNo
.
The track bit mask, trackBitMask
, designates which track to use. Each bit expresses a track in descending order track 0 as the lowest bit. Operations are performed only on tracks with active bits.
panRange
specifies the range of change for the pan set in the sound data. The values between 0 and 127 represent a range of 0% to 100%. The default value is 127. Setting a smaller value narrows the range of change for the pan set in the sound data.
The pan range setting only affects the pan set in the sound data. The pan set by the SND_SetTrackPan
function is not affected.
This function is an ARM7 reserved function. After this function is called, processing occurs only after the command is issued with the SND_FlushCommand
function.
When it is necessary to synchronize something with the completion of the process, first use SND_GetCurrentCommandTag
to obtain the command tag immediately after calling this function. After the command is issued, use the command tag and call either the SND_IsFinishedCommandTag
or SND_WaitForCommandProc
function to confirm that the process has finished or to wait for it to complete.
