The MC-202 and SH-101 used cheap ceramic caps in the filters. I've built 2 Res-EQs one with styrene and WIMA caps and the other with ceramics as a test, the ceramic version has a much more attractive sound IMO.<br>

<div>Hi folks,</div>
<div><br>
</div>
<div>What kind of caps are the grownups using for the VCFs in their synths, especially their polysynths?
<br>
</div>
<div><br>
</div>
<div>I've checked out pictures of voice boards in the DM12, minilogue, and prologue, and I don't see anything sticking out past the SMDs except for some electrolytics, so I assume NP0/C0G is the norm? I don't have much modern stuff to peer inside. In most of
the vintage stuff that I own and have opened, I see polystyrenes. I'd love to know what some of the current, more upscale manufactures are using in their polys.<br>
</div>
<div><br>
</div>
<div>In my own filters, I've noticed polypropylenes often make a sweeter sound than C0Gs, but not always. For eg in high distortion types like my MS20 version, I can use just about anything and it sounds more or less the same. But if I wanted to clone something
like an SH-101 vcf, I'd choose polystyrenes and work from there. The behri version must have C0G though, yeah? They aren't stuffing TH parts, right?<br>
</div>
<div><br>
</div>
<div>In the world of hifi/mastering gear, attractive looking WIMA packages, non-polar electrolytics, and the like, seem to add credibility to a product. I don't see this trend perpetuate in the commercial-synth market, despite VCF-fetishes. At least I haven't
noticed any big manufacturers bragging about their caps. Can the pros design for C0G and make it sound just as good as would something fancier? Or would my DM12 sound a wee bit better if I could somehow bodge in 48 polypropylenes?</div>
