MasterRig compressor limited to 2 bands?


I’m a total newbie to WaveLab Elements 9. I just want to know whether the MasterRig compressor and imager modules in Elements 9 are limited to 2 frequency bands only. I attempted to add more bands by clicking the (+ band) button but it’s grayed out. Is there anything I need to do to activate the ‘add band’ button? Or is this a limitation of the version of WaveLab I’m using? Please help.

The manual says the compressor and imager only have two bands in Elements.

Thanks for pointing that out. Scanned that part of the manual and totally missed it. Thanks again!
