FabFilter

I'm exploring Pro-Q 3 and love it so far. I'd like to experiment with isolating very limited frequency ranges in an audio signal. Make a chord from white noise, for example. Is it possible to drop the overall sound level to 0, then add in the specific frequencies I'd like to hear? I see this can be done by holding the solo button, but is there another way to do this?

I've had some success with creating a notch filter and making the Q as wide as possible, but this doesn't completely cut out the full spectrum of sound.

I hope this makes sense. Thanks in advance for any help.
