I tryed it today. But it did`nt changed anything.

But it was very interesting , because a found something new out !

I made the "gate" Modul direct after the Input and than to the Sampler-Modul.

( Sampler rec in )…and close the gate 0 db ( Signal didn´t reach Threshold at all ) Close. 

The "crackle" came definitely from the Sampler-Modul .

I recorded this crackle also . It ´s 36ms long ! no matter what kind auf Audio-Signal came in.

Means also Softed Attack Audio Material !. And it´s alltime the same.

I think it´s the "Trigger-Prozess" from/in the Sampler-Modul itself.
