SoundToys is one of the most legendary manufacturers of professional plug-ins.
The aim has always been to hit the "magic" of analog effects machines, and some of their plug-ins have a very special status in a professional "toolbox".
Plug-ins like Echoboy and FilterFreak have for many years been go-to plug-ins if you wanted analog-sounding delay and filters that sounded just right.
In recent years, SoundToys has set in motion the development of even more exciting plug-ins such as Radiator, Primaltap, etc.
