Noel96 and all the others,

I've checked all the possibilities of the count-in and here's what I got:
Code:
1-3- 1234    ->   123 123
1-3- 123-    ->   123 123
1-3- 12--    ->   123 12-
1-3- 1---    ->   123 1--
1-3- -2-4    ->   123 -2-
1234 1234    ->   123 123
1234 123-    ->   123 123
1234 12--    ->   123 12-
1234 -2-4    ->   123 -2-
1234 1---    ->   123 1--
1234 ----    ->   123 ---
---- 1234    ->   -2- 123
-2-4 -2-4    ->   -2- -2-
-2-4 -2--    ->   -2- -2-

First, there is no 4th beat at all. Secondly, different patterns are repeated (No 1,2,6,7 and the last ones)

Maybe and hopefully there is someone out there in the Biab community who understands the pattern and can explain the trick behind it.

Any suggestions are welcome
