Unique ten-band filter designed specifically for electronic sound synthesis and processing
The RESONANT EQUALIZER (EQ) is a unique ten-band filter designed specifically for electronic sound synthesis and processing. Except for the top and bottom frequency bands, the bands are spaced at an interval of a major seventh. The Resonant Equalizer is designed to produce formant peaks and valleys similar to those in acoustic instruments.
There are three equalized outputs: the two COMB outputs provide the sums of the two alternate filter bands, while the two top outputs are the (identical) mix of all filter bands. Please note that there is no sharp separation between the bands, moving any frequency knob will have an influence on both COMB outputs. This equalizer is special in that the bands can be set to be resonant: when the knobs are in the middle position, the response at the main EQ Output is flat. When the knobs are positioned between the 9 and 3 o’clock position, up to 12 db of boost or cut is set at the band. If the knob is set beyond the 3 o’clock position, the band will become resonant, simulating the natural resonance of acoustic instrument formant structures. Below the 9 o’clock position, increased band rejection is achieved.
The Random*Source version of the filter is a licensed and authorized adaptation of the legendary Serge equalizer for Eurorack. It adds an input mixer with 2 inputs that can be built/used to attenuate or amplify/distort the input signal(s) before they are sent into the EQ and a Feedback section (knob and phase switch) which allows to feed back the output signal or the inverted output signal (depending on the Phase switch). Adding inverted feedback leads to phase cancellation effects - unlike the “normal” feedback, level decreases and the signal thins out.
Now - licensed by Serge - the legendary EQ is available as DIY kit for Eurorack.

Now we have a black panel for the ResEQ as preferred by some. The ResEQ has been around for quite a while. What I had hoped for is an expander module with CV over all the frequency bands. Add gate sequences and have fun! Much more exciting to me than any visuals ;-) I heard rumors that there is a 4u version of ResEQ with CV control. Anyone?
That would mean building 10 VCA's into the module, not an easy feat and that would be pretty expensive. I've never seen a VC ResEQ, but a fixed filter bank like Bark Filter or Fumana might be what you're after.

I have owned/checked out Antumbra Bank, ADDAC601, Ladik F-110, MMI 295, Moog-inger 914 and guess what - none sounds like the ResEQ. It is very non-linear, with a gnarly resonance where all the bands effect each other. An instrument rather than a processor. VC control would be essential for automating the movement of those knobs. I cannot move more than two of them, much less with any precision. So, no, there is no replacing the VC ResEQ.
For individual outputs of the Res EQ bands: talk to Pierpaolo Cimino (username RTFM).

Thanks, that's interesting. Did he do that for you?
No, but he contacted me a couple of days ago to tell me he has this option for the Res EQ. Great builder (has learned me a lot and got me into DIY) and very nice guy to deal with.
Right, Pierpaolo/RTFM is a great guy to deal with, know that from many occasions.
Pierpaolo is a great builder, I still have a uOc build by him from years ago and still works perfectly like day one!!!

His build quality is SOLID.
Never a problem in about half a dozen of his builds in years.

who is we? where can i get this repanel?
These merchants probably sell this module. Huh?
