Reverb doesn't work and create buzzing and noises

Hi !

I already succeded once or two adding a Valhalla reverb on a “The Grandeur” library for instance, but I had an issue when trying it over my Violins I of my string section.
I appears that when I activate the reverb, the reverb doesn’t sound like it supposed to be, it creates saturation / noises and buzzing ! I also tried changing the presets and no matter wich one I take, the same thing is happening

Thx in advance for you help !

I don’t know, but maybe this question will point you in the right direction (or not! :slight_smile: )

Why does the input show a signal when you switch on the reverb?
