Random Noise on EZD Kick & Snare Track


Sometimes i get a strange noise out of the kick and snare track of EZD in Cubase Elements 8 without any active input or output. This happens on every project since few days. I didnt change anything. Upgraded from cubase 7 to 8 didnt help.
My Specs:
Intel i5-4460 3.2Ghz
8GB DDR3 1333Mhz RAM
Samsung SSD Evo 850 250GB
Steinberg UR22

All drivers are uptodate.

CPU load and noise track on the screenshots.

Any ideas?

Ok, i got it. Its, somehow, because of the Melda Production Plugins…they just worked fine…and now, theyre making noises.
