Third batch of the old school VCA has landed. A few minor changes have been implemented in the design to get rid of the annoyances I encountered using them. And since I’m the C-level executive of S&C, whatever I say goes! I also empty the trash bin and mop theRead More

For another project I’m working on I needed a multimode filter. For the uninitiated, its a single filter that has a HP/BP/LP function, and does it all simultaneously. An OTA design is fairly common for this type of filter, so that’s what I did. Now, there are a zillion differentRead More

I accidentally, a filter. Who knew that could happen. Maybe I’m picking something up about that whole electronics stuff after all. One can dream. But here it is and I proudly call it VCF-2, quite original, I know. But I ran out of cool sounding names a while back soRead More

There’s that saying that you’ll never have enough VCA’s in your modular system. IMHO you never have enough of anything in a modular, but let not digress. VCA’s are useful little buggers that you simply can’t do without. I’ve build a variety of them in the past, mostly incorporated intoRead More

You cannot build a modular without any mixer modules. I’ve made quite a few mixer modules by now and I noticed I hadn’t put anything up online. So, I’m rectifying this oversight with this post.Read More

One needs an LFO. How else could you go wob-wob-wob?Read More

I’ve been asked if I could do a workshop about synth building. While there are no solid plans to do so yet, I was thinking about what to build during such a workshop. It would be cool to have something to take home you’ve build yourself during the workshop, andRead More

I found myself short of an ADSR in my system and it annoyed me to no end I hadn’t thought of buying a few more. Instead of hitting the favourite Eurorack module dealer for my fix I went googling to see if I could cook up one of my own.Read More

This is an envelop follower. Since I build an input module I kinda wished I had one of these so I made it a little project, fun for the whole family well, not really, but anyways..)Read More

Since Coolaudio started reissuing old IC’s used in various synths I always eyed the V3340, which is a reissue of the CEM3340 chip as used in many classic synths such as the Roland SH101, Prophet 5, Memory Moog and plenty of others. It’s, in essence, a fully featured 1V/oct oscillatorRead More
