0 1 word marker, value=0x6669
2 108 bytes song message
0x6e 1 byte NOS = number of samples saved (0-64)
0x6f 1 byte NOP = number of patterns saved (0-128)
0x70 1 byte loop order number
0x71 0x80 bytes order list
0xf1 0x80 bytes tempo list for patterns

this is repeated 8 times for every row and the array of 8 of these is
repeated 64 times for each pattern.

bits:
BYTE[0]: BYTE[1]: BYTE[2]:
aaaaaaaa bbbbbbbb cccccccc


4 bit volume command value

aabbbb = 6 bit instrument number command:
0 = a
note value = (12*oct)+note 1 = b
2 = c
special values for byte 0: 3 = d
0xfe = no note, only volume change 4 = e
0xff = no note or volume change 5 = f

special value for byte 2:
0xff = no command


0x1f1+ rest of file samples
