# SND_SetChannelPan

## C Specification

      #include <nitro/snd.h>

      void SND_SetChannelPan( u32 chBitMask, int pan );

## Arguments

`chBitMask` | The channel bit mask. It specifies which channels to control.
`pan` | The pan. Takes values in the range of 0 (left) to 64 (center) to 127 (right).

## Return Values

None.

## Description

Changes the channel pan.

The channel bit mask `chBitMask` specifies which channels to control. The channels are represented in order, with the lowest bit representing channel 0. Only channels whose representative bits are standing are controlled.

### Caution

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.
