creating a smooth gain dip in a 1 knob filter sweep rack

Easy guys, just wondering if anyone has any ideas as to a solution for this?

I've created a simple hi-pass filter rack, with filter freq, resonance & also gain (via utility plug) mapped to 1 macro/controller knob...

here it is - https://rcpt.yousendit.com/610968887/2f ... 5a5ca41ffe

The sound of the filter is exactly as I want it EXCEPT for the area between 31-50 of a sweep (of the 127 controller steps) where the resonance gets a too little boomy - but if I move the resonance map either side I lose the sound I want from the filter outside of the 31-50 range.

sooo... is there a way, still using 1 macro/controller knob, to create a smooth gain 'dip' of a few db in gain whilst the macro goes through this small frequency band?

Cheers

you could try racking two different filters with slightly different Q setups and crossfade between them in the rack?

What clearscreen said. I often need to do this with my DJ Racks, adding extra layers in the rack just to help even out the volume.

Cheers guys, just had a chance to play with this - couldn't get the fades or attenuation as smooth for the sweep as I'd like with layers but did come up with another solution with gains (utility) at the start & end of the frequency bands (one to lose the boom, & an extra one for good measure to attenuate the harshest tops) - mapped to their extremes but turned off until they reach '0' on the 1 knob macro. works a treat!
screengrab below in case is useful for anyone else wanting to do the same
