to rec my trash I am now using Guitar Rig 2, but here is the problem: both with clean or distorted, listening carefully it is possible to notice a "noise" while the instrument is silent.
I downloaded the demo clips from the main site of Native Instruments, but that noise is not present (and they are claiming to use the same Guitar Rig 2 as me :) ) so... where is the secret? how can I remove that annoying noise?

thanks :)
