IVGI ~ Saturation & Distortion


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 reacts dynamically to the input signal. Even the modeled 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 modeled crosstalk behavior.

IVGI features a Controlled Randomness, which determines the internal drift and variance inside the unit. It contributes to the liveliness and realness of IVGI’s saturation character. To achieve this, all internal processes are modulated to some extent.

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.

IVGI also lets you alter the frequency dependency of the saturation with the RESPONSE control.

CamelCrusher ~ Compressor | Distortion


CamelCrusher is a free ‘colouring’ multi-effect plugin. It offers two characteristically different distortion sounds which can be blended together to create a wide variety of tones and textures. Great for guitars, drums and plenty more!

There’s also a warm, smooth analogue-style low-pass filter with buckets of resonance. Assign a MIDI controller and start tweaking!

Finally, let’s not forget the easiest-to-use compressor you’ll find anywhere. It can ‘phatten’ up your sound as quickly as you can turn up the ‘Amount’ knob! Find out more in the manual.

Best of all, CamelCrusher is available free of charge!

Features:

  • Two different distortion types.
  • Warm, analogue-modelled resonant low-pass filter.
  • High quality, easy-to-use compressor, with ‘Phat’ mode.
  • Powerful ‘MIDI Learn’ function.
  • A collection of useful Preset patches to get you started.
  • Randomize for instant inspiration.”
