3B6h           1         Number of pattern to play
3B7h           1         7Fh (set that way for some
                         OLD NoiseTracker replayers )
3B8h         80h         pattern table

438h           3         { 'W','N',0x00 }  ID string
43Bh           1         real number of pattern (thx Gryzor's ProWiz !)
43Ch           ?         Pattern datas.

 each pattern takes 400h bytes
 row 00 | channel 1 | channel 2 | channel 3 | channel 4 |
 row 01 | channel 1 | channel 2 | channel 3 | channel 4 |
  ...
 row 63 | channel 1 | channel 2 | channel 3 | channel 4 |

 each channel is coded that way :

 0000 0000  0000 0000  0000 0000  0000 0000
 \       /  \       /   |   \  /  \       /
 relative    sample     |  effect  effect
   note      number   unused       value
  number     0 -> 1f


relative note number (PTK):

C-1 to B-1 : 856,808,762,720,678,640,604,570,538,508,480,453
C-2 to B-2 : 428,404,381,360,339,320,302,285,269,254,240,226
C-3 to B-3 : 214,202,190,180,170,160,151,143,135,127,120,113

becomes (WN):
