All,

 I've recently spent some time on an unknown (to me) protracker clone format. I don't know the name nor the author. The material is found only in Devils prods, so .. I've made up this very original name "Devils replay"

 I started looking at this when handling this No Reality demo by Devils. Rather quickly, I found that it's the very same format as found in Colors demo, also by Devils.
 Cybfree, once again, quickly reminded me that this format was already beaten - more precisely, the musics from Colors were already converted. Great !, so, I can write a quite converter myself for the others.

 That's exactly what I did. It took me 3 days because I'm still not great at coding, but it's done. So, first, all the cases found are here:

 The format itself is somewhat unique in that it does things I've not seen elsewhere. Promizer could be a distant cousin of some sort

standard protracker header until 'M.K.' at 1080
1084          short         size of pattern data [A]
1086 + [A]    short         size of reference table [B] - must be at an even position
1086 + [A]    short         sample data
+ 2 + [B]     

pattern data:
192 bytes per pattern
3 bytes per row:
 0 byte : filter
 1 short : address to read in reference table

Reference table:
contains rows of output unpacked notes - so up to 16 bytes.
depending of the filter, above, the blocks of word/short are stored
filter : abcd-efgh
output: in 16 bytes
B1 B2 B3 B4 B5 B6 B7 B8 B8 B10 B11 B12 B13 B14 B15 B16

  a     b     c     d     e      f       g       h
if the filter bit is set, the corresponding output is stored in the reference table.

 I guess that's it. No sure I was too clear on this one. Please, report back if you want more details.

 Again, huge thanks to Cybfree for the help.
