Not Peter, but, you're right. Here's a snippet from the T-RackS User Guide:
The Quad Comp is one of the four modules in the Multiband series of IK Multimedia plug ins for T-RackS. Multiband processing at the core of this plug-in splits the incoming signal into up to four frequency bands and treats each one separately with a dedicated set of controls. The width of each band can be finely adjusted so that the processing can be very selective (in case of a narrow band) or spread across a wider range. Each band is loaded with an optical compressor of particular effectiveness but with a very smooth sound and a full set of adjustable parameters.
