Synthesizers used to be big. Very big. The Teenage Engineering x Cheap Monday Pocket Operator is a synthesizer, but it isn't big. In fact, it's small enough to fit in your pocket, yet still offers a host of analog controls, high-quality components like a Silabs EFM 32 gecko CPU, Cirrus logic DAC, and Knowles speaker, and features like an LCD with animated graphics, real synthesizer engines, punch-in effects, 3.5mm input and output, and a folding wire stand. Available in three models: Rhythm, a drum machine, Sub, a bass line maker, and Factory, a melody synthesizer.
