Hi, i plan to build a true stereo filterboard for Shruthi/Phoenix.
Ok we have some filterboards … but not in stereo …
The Plan . Two filter one for R one for L . Adjustable with CV 1 and CV 2.
The schematics is ready , today i have made a first test how i can add CV1/2 and the frequency control.
It is possible to set the L channel to LFO1 and the R channel also to LFO 1 but with 180 -degree so that it gives a nice stereo modulation .
With the mod Matrix it is also possible to control Filter R with ADSR 1 and Filter L with ADSR 2.
More comes soon . Next i will build the first prototype and post some pictures and the schematics .
Can you add a Pan/Balance destination to the mod-matrix? LFO-controlled panning was one of the nice features of my old Waldorf Miniworks standalone filter.
Hi Benne,
seems that it is too special. in spite it sounds very interesting i have less response. @Toneburst, yes this is the trick , you can modulate the Filter R in the mod matrix with the LFO1
and Filter L also with LFO1 but -180 degree. So it should give nice panning . Also you can select all sources and send it to CV 1 and CV2 . CV1 is filter cut R , CV2 is filter cut L . On the Picture you see at first the double LOG converter for Filter L and filter R.
Next more and the first schematics. BTW i will also improve the VCA . I have here a new circut and it seems that it works better than the original SMR4 one.
Let you surprise , i also let me surprise how it sounds .
Hi, 2 vca, yes,separately controllable, no. This because i have only two cv controls.
But i think 2 filter controllable is more than ok.
We will see , ahh… hear.

Andre, I don’t think you can judge to potential market for a eurorack filter from the lack of interest in a Shruthi filter board - the eurorack market is much bigger. However, so is the competition.
Hi Guys , i know it with the eurorack, but we have a lot projects in the pipeline before…
The stereo filter is for me to warm up. I build it just for fun because i will hear how it sounds.
I have made the schematics now since a jear . BTW , it is the improoved degenerator filter board . Yes and than the degenerator. It is a little bit silent with the degenerator , but , we work hard on it . The software is round about 80…85 % ready. And Rolf had become gray hairs…This is the next Big project . Rolf and i phone nearly every day to discuss the schematics and the software functions . and AFTER this, in plan is a euro rack sampler. We have now all the C++ procedures ( the same like in the degenerator ) and we can use the same CPU ( maybe a better one ).
This comes hopefully in the beginning of next year. And than we start with some other eurorack modules.
Than there are some small things like a stereo filter BOX and i think since 2 years about a DIY vocoder. Oh God give me more time…
short form .
1:) stereo Filter for Shruthi------ for christmas-----
2:) degenerator
3:) eurorack Sampler
4:) maybe a stereo filter box , based in the P4 filter, 2 LFO’s, Ring, soft dist … Rack and standalone.
5:) and if i feel mad enough a 12 band vocoder …
After the Degenerator we will design all modules in this way that you can use it as a eurorack module or standalone .
