Leonardo Laguna Ruiz of Vult spoke with us about modelling electronics, modular synthesizers, and modulating sound. We talked in detail about applied digital signal processing.

Leonardo’s website is www.vult-dsp.com. Check out the Freak Filter, the user manual alone is a course in signal processing. You can buy finished or DIY versions on vult-dsp.com/store. 

The physical hardware is a Eurorack module (wiki) but the Vult modules are also available for the VCV Rack, a Eurorack simulator that you can use to build your own modular synthesizer. 

Leonardo has a YouTube channel where he goes in depth on signal processing: youtube.com/c/LeonardoLagunaRuiz. He’s also written about modeling vintage analog sound on the Wolfram blog.
