I found the EFM Wildcat on SynthDIY.com , I used VCF2 . Some of the schematics had component values missing , had to do a bit of trial-and-error to get it working , mostly around the resonance control ...

Thanks peter. I never thougt it can be so low and still functioning.

Hi all,

Am I missing some (basic) knowledge? I built the micro S&H from MFOS to add it to the MFOS SynthDIY but on the first test (breadboard) I realise that it consume nothing.

Hi ! I had similar problems with the VCF . The specified FET is like Unobtanium in UK , so I tried 2n5457 , 2n5458 and 2n5485 , no luck all round . Very faint audio output , all voltages seemed sensi ...

Hi all and thanks for the replies.

I undestand the need of a nice design if it was for a stable/1Voct etc modular.
This is why I said about a simple (not really 1Voct or anything) VCF.

Hi all,

Any pointers to a simple VCF to build alongside the MFOS SynthDIY that Im building?

The original one seems to be either really subtle for my taste or I tryed bulbing it 2-3 times without ...

I just tried to simulate this circuit in LTSpice, and I got pretty much the same results as you (<20mV output from a 1V input).
Probably something we're missing..

Which trimmer pins are 7.5V? Is it 7.5 on all pins?

Hi and thanks for helping.

Hi All,

Im building the synth DIY, the VCOs and the LFO are ok but it seems that my VCF is not working.

Im feeding 10khz Square 2 to 4Vpp and I dont see any action in the output.. maybe minor sq ...

Perfect for experimental coding and learning DSP.
I'll take one soon!

Im interested too!

Is there a possibility for a run??

perfect. thanks!

EDIT: I read a lot of pages from his blog and scanned a couple of french forums but even though he talks about 2 kits version, I cant find a link :S

Are you planning to release any schematic and source for this?
Thanks
