ModulTone Mid/side mixing plugins
Plugins that give the middle and the sides of a stereo mix their own controls. You get more control over a wide, or even huge, stereo image, and a mix that still sounds right in mono.

Made on my own sessions.
My name is Ivo Janssen and I'm a pop producer, mixer and songwriter. I made these plugins to quickly make my mix sound professional when I need it most. I tried making the controls as easy as possible while still giving you enough options to play with. The plugin MS Saturator came out of a chorus that wouldn't land: parts right, balance right, and the bus mix still sitting in the same narrow space as the verse. Everything since has come from that.
