<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Thanks to their use in mobile phone, ceramic capacitors have come on a long way in the past 20 years. You won’t find microphony in any of the good brands
(I always specify Samsung or Yageo), be they NPOs or X7Rs. Imagine what a smartphone would be like if it was microphonic ?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The only time I can think of a ceramic in a filter sounding different would be in a Moog ladder if you were running flat out – at very high voltage swings there
is a slight capacitance change with voltage, though this is more with X7Rs than NP0s. I imagine commercial synths just keep the signal levels down to stop this becoming an effect. <o:p></o:p></span></p>

<p class="MsoNormal">Hi folks,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">What kind of caps are the grownups using for the VCFs in their synths, especially their polysynths?
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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?<o:p></o:p></p>
