Wish Mix Control in Filter Block

would be great to have a simple dry/wet mix control (as in most other blocks) in the Filter block.
a feature that can be found in most modern synths, that can be very powerful especially when using more extreme filter types such as Bandpass etc., which can then be blend with the dry signal for more subtle textures...

+1 Especially.....now that the filter block has the LFO built into it; it is or can be more easily used as much as an "effect" block ::: please, please, please. I am using it as a filter sweep (fx), and I want to be able to (most easily) control the wet/dry mix
 
I made an account just to ask for this! The mix feature is very useful on my Moog Low Pass filter. Was a bit bummed to not see a mix feature on the mix page.

Thanks.

A lowpass with mix is a lowshelf.
I'm probably ignorant, but I thought a lowpass filter had infinitely increasing rolloff below EDIT: above the cutoff frequency, where a low shelf in cut mode eventually flattened out. Am I missing that those are equivalent when there's a mix control?

That's a highpass.

A lowpass with "direct" signal mixed in is a lowshelf. A highpass with direct signal mixed in is a highshelf. In fact in the analog domain that's a common way of making low/high shelf filters.

It's intuitive as well. Take the direct signal and add/subtract some lowpass filtered signal. Now you have a bass boost/cut, i.e. lowshelf.

Yes of course, I misspoke. It's been a long week...

Hmmm, I guess that's true, hadn't thought about it that way.

FWIW the Lowshelf2 and Highself2 types are "analog" types and derived using "k + low/high pass".
