 - Size of pattern list (x4)
- Pattern table. It is the address of the
patterns. First is $00000000
- Size of ALL the pattern data
- Pattern data. Stored 'almost' like Protracker. The difference remains in the fact that you have to 'NOT' all the 4 bytes save for the 4 lower bits.

we get something like that:

pattern 0 :
  • row 0 | voice 1 | voice 2 | voice 3 | voice 4 |
  • row 1 | voice 1 | voice 2 | voice 3 | voice 4 |
  • row 2 ...
  • row 63| voice 1 | voice 2 | voice 3 | voice 4 |

    • pattern 1 : ...
    Note Packing :

       \           /         \/    \     /
        Note value         effect   effect
                                  parameter

  • Promizer v0.1 (as v1.0c and v1.8a) saves the "finetuned" pitch if the sample got a 'not null' finetune. Refer here where there are all the possible pitchs for each finetune

    • Follow Sample datas stored like Protracker. Nothing is packed..
