This tiny, handheld synth features two light sensors, two pots, and two buttons. It’s an easy build, even for newbies, soldering together very quickly with no difficult steps. I love how snug the little guy is, but this compactness comes at a price: no enclosure and no speaker. To hear the Pico Paso, you’ll need a ¼” mono cable to connect it to a mixer or amp.
