Ok, i make mistake with sawtooths, maybe. I think i am close with my patch, what only i need is proper EQ now only and it will be the same or very close i think
FBX patch
In this sound example you can hear first sylenth (i download the mp3 from first post), then Dune 2, etc..
mp3
PS: the big diference is with unison voices and reset phase. Then i must add one voice with non reset phase because dune2 reset is more agressive then sylenth, for me.
