    The macchiato is a superb little device that is easy to play and even easier to transport. The controls are very functional, providing a customizable sound that fits any tone of melody I want! Each knob has a different purpose to help you fine tune the sound of your synth, allowing a wide range of tones to fit into one small instrument. I could mess around with the macchiato for hours and still not run out of variety. I love my mini synth!

    I’ve been messing around with simple theremins and guitar effects pedals for the last year or so, and was eager to branch out into simple synthesizers. A coworker showed me the Macchiato, and I think I had placed my order within thirty seconds. The kit is well designed, the instructions are well written and in-depth (they also include a lot of “how this works/why this is does what it does” type of information, which I was very thankful for), and it was a blast to build. Within a couple hours I was beeping and booping, learning about LFOs and different wave shapes. This thing is endless fun, and I could not be happier with my purchase! They’re also made right here in Chicago, which is awesome.
