Curious if you'd notice similar from circuit emulator synths like Diva: https://www.u-he.com/cms/diva https://www.u-he.com/cms/diva

  The Diva is good, but doesn't sound like an analogue synth.

  Where can I find information on simulating circuits -- the underlying algorithms and models? Does it take in account factors like temperature (I hope so)?

    Here's a good place to start - the blog of Urs, the guy who made Diva. https://urs.silvrback.com/ https://urs.silvrback.com/ Andy Cytomic is also doing good work on analogue filter modeling https://cytomic.com/index.php?q=technical-papers https://cytomic.com/index.php?q=technical-papers

      This isn't analogue modelling though -- you're just using KVL/KCL to derive the transfer function H(w) and applying the same transfer function as a digital filter. It's literally the first thing I would do if I wanted to come up with something that sounded the least bit like the real thing. I was using my own FIR derivation of a third-order low-pass Butterworth filter to do software synthesis in 2008 while I was in high school. This is truly basic stuff. Real analogue modelling has things like noise, hysteresis, and a dependence on such broad factors as temperature and even EM fields.

        I guess I should have done my own digging. THIS (and really anything Spice does) is REAL analog modelling: https://pdfs.semanticscholar.org/f03a/310c40a48be62206ce5ff1352bd61e88599e.pdf https://pdfs.semanticscholar.org/f03a/310c40a48be62206ce5ff1...
