Waves OneKnob Filter

Does anyone else have this?

I just bought it on a sale as I thought it might sound a little better than Abletons filter, however for the life of me I can’t seem to change it from a low pass filter to a high pass? Is it not possible? It seems weird and unusual they’d only make it one sided so clearly I’ve missed something, I’ve been looking all over, I’m torn! I even tried the online video, but it just shown 52 seconds of the low pass filter.

Ableton 9 autofilter uses cytomic filter dsp which is pretty much the best out there.
