Analogue Filter for DJiinG - HELP NEEDED

[fosforo]

Hi to all,

i would like to build an analogue filter (resonance,cutoff,hp/lp) to use with my DJ setup.
The idea is to feed a CDJ into the filter and then the filter to the mixer.
I've searched around the web and came out some projects related to analogue synths (VCF) but they seems needing a CV to work.
So, i was wondering if someone could help me finding out a project or some idea to do that.
Any Idea will be very appreciated.

🙂

Many Thankx

Fabio

You would have to discount the Sallen-Key filter as it would require a potentiometer with more than 2 gangs for stereo, which makes it hard to find and expensive.

Maybe multiple-feedback filter is suitable, I don't know you will have to research that yourself.

Otherwise a voltage-controlled filter chip is the only other realistic option.

I found this one.
It's a copy of the original moog filter.
What i have to understand is how i can use it...

use a potentiometer as a cv generator?

if you find an analog filter that requires a CV to work, then just make a pot provide the CV to the filter. it requires no extra components, and voltage control filter designed for synths should work great for you. you can even use a VC pedal which is a big foot pedal like a "wah wah" connected to a pot. it will give you a control voltage for the filter.
