SND_PrepareSeq

Syntax

#include <nitro/snd.h>
void SND_PrepareSeq(
        int playerNo,
        const void* base,
        u32 offset,
        const SNDBankData* bank );

Arguments

playerNo The player number. Takes a value between 0 and 15.
base The base address of the sequence data.
offset The start position offset for the sequence data.
bank This is the bank data pointer.

Return Values

None.

Description

Prepares the sequence for playback.

Prepares the sequence for playback on the player indicated by playerNo. Any sequence that is already being played on that player will be forcibly stopped.

Sequence data is processed from the offset position (offset) from the base address (base).

For bank, bank, specify the bank which the sequence uses for sound generation. The SND_AssignWaveArc function must be used to combine the waveform archive with the bank in advance.

Call the SND_StartPreparedSeq function to play a sequence that has been prepared for playback.

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.
