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's base sound is comparable to the DESK mode in the big brother SDRR.
Just as SDRR, IVGI reacts dynamically to the input signal. Even the modelled fluctuations react dynamically and also change depending on the drive setting, so that it doesn't get in the way of the SOUND. Stereo tracks benefit from it's modelled crosstalk behaviour. Just as its big brother SDRR, IVGI features a "Controlled Randomness", which determines the internal drift and variance inside the unit. It contributes to the livelyness and realness of IVGI's saturation character. All internal processes are modulated to some extent to make this possible.
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.
