Hi there,

Just a quick feature request.
Would it be possible to implement a negative gain scale for future versions of ProQ?

Main usecase for me:
Boost certain frequencies before distortion or any other processing, then cut them after.

The harmonics or effect of the boosted frequencies will be more pronounced, but you can dial back any resonances created afterwards by copying the preset and reducing the gain scale to a negative number until it's fixed.

I could think of a number of other usecases, but this specifically would be a huge one for me.

Cheers, thanks for all the hard work!
