Over the last years, I have built a lot of synthesizer circuits. Every time a model a synthesizer piece I end up building a circuit that I use as reference. These circuits can be breadboard circuits, commercial DIY kits, or full PCBs. Most of the times I end up doing nothing else with these circuits and I either destroy them, put them in a box, give them away to friends or I add them to my rack.
In a few occasions, I make full eurorack modules. For example, some years ago I designed the PCBs and panel for a Steiner-Parker filter. I gave away the boards to some of my friends and I believe that there are 4 "copies" in existence.
For all the other modules that I have designed (and shown pictures) people often ask me if they can get one. Usually, I'm a bit reluctant because there could be small issues that may need fixing in order to have polished product. Additionally, if I want to turn these modules into products I need to make sure there's a minimum demand that justifies the development efforts.
The last module I designed is the Wolv wave shaper.
I designed this because I wanted to model the circuit originally conceived by Ian Fritz. This resulted in the virtual Wolv version.
The main reason why I decided to build this is because, as far as I know, it is a very different type of waveshaper. It also seems to be not very popular since I could find just a couple of videos of people showing it. If you want to have an idea on how it behaves, you can check the following video:
