Possible to control freq via pot for RDFX/WRHX?
Posted: Sun Mar 22, 2015 9:07 am
I figured out how to control frequency and resonance for two pole filters using MULX with a POT input, but these filters do not use RDFX or WRHX/WHLX.
Before I spend the rest of the day slamming my head into the wall I'm wondering if it's even possible to pot control freq and shelf with the RDFX/WR?X combination. If so, a hint would be vastly appreciated!
Update: nice section on this in the Knowledge base. Quick answer = it's a little more complicated.

This example covers adjusting the shelf depth via control. How about the frequency?
Thx,
