The Fat Channel is a stock plug-in of Studio One and therefore a unique feature of Studio One. The Fat Channel is an integral part of the StudioLive mixers of all generations, which in the times of "Active Integration" (AI) was transferred to Studio One in order to be able to use the same sound processing in both worlds. The Fat Channel plug-in was designed as "container", which now can host the StudioLive Series III Fat Channel Plug-ins (modeled equalizers and compressors).
