Halion Sonic Bug?

I think I spotted a bug on my system; when I load Halion sonic, I can hear a low modulated and distorted sound coming out of the plugin even if there is no patch loaded…
Anyone having the same problem?

up!

Didn’t spot that last night during setting everything up.
Does it show up visually in the mixers ??

Yes it does show on the meters.
I also got the bug with NI Massive and Kontakt too… looks very random.
When I get the bug on one instrument, I can’t use it in the project anymore, others work fine for now but It seems the bugs comes for no reason on any VSTi.
I’ll probably have to reinstall everything and pray…
