KORG format file structure
There are three types of files: .KMP files for multisamples, 
.KSF files for samples, and .KSC files which handle the first 
two as a collection. Similar to the AIFF format, .KMP/.KSF 
files consist of chunks.

Unless stated otherwise, all data is Big Endian.

●

When a Korg format file saved on the TRITON Le is loaded 
by the TRINITY,
• Of the parameters for each song, the following 

parameters are ignored (the chunk that includes the 
parameter is given in parentheses)

• Of the parameters for each sample, reverse playback 

and loop off settings (included in the attribute 
parameters of the SMD1 chunk) will be ignored, and 
will be handled respectively as forward playback and 
loop on. Only the twelve types of sampling frequency 
supported by the Trinity will be loaded correctly, and 
if the frequency is unsupported, the next lowest 
frequency will be selected.

• Split sample files cannot be loaded.

●

When a Korg format file saved on the TRINITY is loaded 
into the TRITON Le,
• Compressed sample files cannot be loaded.

• Multisamples that use internal samples of the Trinity 

will be assigned identically-numbered RAM samples.

These consist of the following chunks.

●

• Attributes

●

If the .KSF filename is “SKIPPEDSAMPL”, it will be treated 
as a sample skipped during loading.
If the .KSF filename is “INTERNALnnnn”, internal samples 
will be used.

●

●

There are four types of structure for these files. One consists 
of a Sample Parameter chunk, Sample Data chunk, and Sam-
ple Number chunk (SMP1 + SMD1 + SNO1). Another con-
sists of a Sample Parameter chunk, Sample Data chunk, 
Sample Filename chunk, and Sample Number chunk (SMP1 
+ SMD1 + SMF1 + SNO1). 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 SmartMedia 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 con-
sist of the Sample Parameter chunk, Sample Number chunk, 
a divided Sample Parameter chunk, and a divided Sample 
Data chunk (SMP1 + SNO1 + SPD1 + SDD1), and the second 
and subsequent files will consist of a divided Sample Data 
chunk (SDD1).
