Hey, Thanks a lot for a quick reply.
Doing VST reset did the trick. I have been looking for a solution of this last 4 hours :(.
Now I have a new problem (not related to this): when I use the SI Drum kit, I hear a loud ring associated to playing any of the tom and bass drum. I can hear this same ring while using SSD5 drums instrument.
Only plugin where I do not get this ringing noise is in mt drum kit 2. Any idea why?
