Offset  Bytes   Description

0       2       Sample 1's segment (samples offset/16)
2       2       Sample 1's length
4       1       Sample 1's volume
5       1       Sample 1's finetune
6       2       Sample 1's repeat begin
2       1       1 = loop the sample, 0 = don't loop

10     10       SAMPLE 2 : like sample 1

.       .
300    10       SAMPLE 31

310	1	Song lenght

312     128     Song positions 0-127 (values 0-63)
440     8       not used (these are here to make the patterns start at a page
                        boundary)
