IVGI can deliver very soft and subtle saturation, that feels at home on the master buss.
It is equally capable of very dense and dirty distortion effects to spice up single tracks. IVGI gives you a sensible amount of controls to manipulate the character of the saturation itself. It offers a unique ASYM MIX knob to alter the symmetry of the signal without affecting the harmonic content much. Usually, asymmetry leads to an increase of even order harmonics. But in IVGI's case, dialing in the asymmetry makes the negative part of the signal “cleaner”. This way you can preserve the dynamic structrure of the source better and get a more transparent result. Actually, you can think of ASYM MIX as a transparency control. IVGI also lets you alter the frequency dependency of the saturation with the RESPONSE control. IVGI is internally calibrated to 0VU = -18dBFS.
