Modular Musical Synthesizers are very, very cool. They are also very, very expensive and complicated. The bar to entry, both in terms of cost and understanding, preclude a lot of people from trying it out. What I envision is a simple modular synthesizer comprised of self contained modules that won't require racks or enclosures. They connect to each other with patch cords, and the circuitry is designed such that it is impossible to damage anything by making a wrong connection. Think ... if Lego designed a synthesizer. . . .
I see the user of this system being someone who wants to try try synthesizers without shelling out a couple thousand dollars. Or a first synth for a teenager on a limited allowance. Or a tool in an elementary school classroom, or a rugged instrument for a high school, both of which exist with hugely constrained budgets. Low cost and totally open. I'd love to see what people can do with this.
Separate BOMs are provided in the GIT Repositories given with each build log.
The modular nature of my HackaDay Prize entry suggests that I will be building a lot of small PIC based circuits. For quite a while I was a huge fan of the tiny PIC Proto board produced by TAUTIC Electronics. Unfortunately they are not available any more so I decided to design my own, and while I was at it, design it to fit into the enclosure I hope to be able to use for my synth modules.
