Nice job on the video--very helpful explanations. Would love to see more of these. Here's a link to some background on the SSI team and the SSI2144 (SSM2044 reissue) is used on the Sequential Prophet X. sonicstate.com/news/2018/06/07/-sound-semiconductor-filter-chip-for-prophet-x/
Thanks for the link! It's wonderful to see these chips (and even better ones) being made again. For years the assumption was there wouldn't be enough of a market to make it worth doing a run because the setup costs for making ICs is so high.
Yes, there's quite the comeback in these chips! Here's an article from a couple years ago: electricdruid.net/analog-renaissance/ This is an interesting company in Latvia (where they still have the technology to make older analog chips!), not only do they make their own version of the 2164 and many other "modern" 1980s era analog synth chips, they're remaking many other obsolete-but-desirable parts as well, such as the LM394 "supermatched" transistor pair, and the the earlier OTAs CA3080 and CA3280. (!) www.alfarzpp.lv/eng/sc/application.php Unfortunately most of these reissue chips aren't available from the usual big distributors such as Digikey and Mouser. About the closest to a "real" USA distributor I know of is Small Bear, smallbear-electronics.mybigcommerce.com/ which only carries a few of the parts made. If they don't have the part you want, the alternative is third-party sellers on ebay and reverb.com.
These videos are golden! I'm not huge on math, but these provide excellent information regardless. For an example, the video on the ladder filter is the most comprehensive one on the subject out there without going into NASA-levels of math while keeping it practical. I really hope you'll continue these after this whole pandemic thing.
Very Nice Congratulations Adoro os chips CEM para circuitos de Sintetizadores analogicos. A muitos anos atrás cheguei a conversar com um dos responsáveis do fabricante desses chips. Pena que não comprei alguns. Thank You very much Cheers from São Paulo-Brasil
Love this videos!!! thank you men! Im learning a lot with this videos. I have a question regarding this video: Why most synths use OTA´s (or some 2164 clone) and not blackmer vca´s? Arent they worse? thank you very much for the videos!!!

Thank you for your kind words!
Wow now this is the kind of stuff I’d love to have studied at uni
Ha, found you! Watched your EMS2006 series, could only hope that you would do something like this. But here you are :D . Thanks for everything.
Big fan of these videos!
In the functional block diagram of the SSI2144 chip, there's also an oddly shaped trapezoid OTA! :D
That is indeed such a weird chip! Its OTAs have differential outputs.
Whoooooaaaaa!!!! 🎛🤖⚡
Very Nice

Awesome video, thanks!
You are welcome! :)
Another fanastic video :3
I wonder if I can use it on a basic VLF metaldetector... so a bolt won't blow your ears off when you are listening for the faint zip sounds..
