- Sample Name
- finetune (signed word)
- Sample Size / 2
- ?!?
- Volume (0 - 40h)
- Loop Start / 4 (or / 2)
- Loop Size / 2 |
Note: about this loop start /4 or /2,
I keep it that way knowing there were the two possible cases in UNIC format.
UNIC2 file I have, have all this value /4

- Number of pattern to play
- Noisetracker byte set to $00
- Pattern table
- Pattern datas. |
Patterns are stored one after another and each is 300h bytes long.
One pattern is like this (like PTK) :
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 |
The note packing :

0000 0000 0000 0000 0000 0000
| \ / \ / \ /
| relative effect effect
| note value
| number

unused
|
Effect :
Just note that pattern break effect command (D**) uses HEX value
in UNIC format (while it is DEC values in PTK). Thus, it has to
be converted !
relative note number:
