KSF (KORG Sample File) files
There are four types of structure for these files. One consists
of a Sample Parameter chunk1, Sample Parameter chunk2,
Sample Data chunk, Sample Number chunk and Sample
name (SMP1 + SMP2 + SMD1 + SNO1 + NAME). Another
consists of a Sample Parameter chunk1, Sample Parameter
chunk2, Sample Data chunk, Sample Filename chunk, Sample
Number chunk, and Sample name chunk (SMP1 + SMP2 +
SMD1 + SMF1 + SNO1 + NAME). The latter structure is in the
case where the sample data of the Sample chunk is empty,
and uses the sample data of the .KSF file specified by the
Sample Filename chunk (shared sample data).
When saving to a floppy disk and a single media cannot
accommodate all of the data, it is possible to automatically
divide the file and continue the save operation.
When a .KSF file is created in this way, the first file will
consist of the Sample Parameter chunk1, Sample Parameter
chunk2, Sample Number chunk, and Sample name a
divided Sample Parameter chunk, and a divided Sample
Data chunk (SMP1 + SMP2 + SNO1 + NAME + SPD1 +
SDD1), and the second and subsequent files will consist of a
divided Sample Data chunk (SDD1).
• Sample parameter chunk1
Note: Sample parameter chunk 1 is used by the TRINITY
series, TRITON series, and TR.
• Sample parameter chunk2
Note: Sample parameter chunk 2 is used by the OASYS,
TRITON series, and M3.
• Sample data chunk
• Attributes
• Sample number chunk
• Sample name chunk
• Sample filename chunk
If the .KSF filename is “SKIPPEDSAMPL”, it will be
treated as a sample skipped during loading.
If the .KSF filename is “INTERNALnnnn”, internal sam-
ples will be used.
