Modular Audio Devices is an ecosystem of handmade Eurorack modules designed in Italy, that aims at providing classic analog tools as well as modern digital ones. With its original idea going back as far as 2013, Modular Audio Devices has since then evolved into a complex line of yet-to-be modules for synths, controllers, audio interfaces, preamps, and so on. The first commercial product, AVCO, a classic analog oscillator based on the 3340 chip, is going to be released in the next weeks with a crowdfunding campaign to help fund its production as well as the development of future module
