Small enough to fit in your pocket and powered by a pair of AAA batteries, the Teenage Engineering PO-28 Pocket Operator Robot Synthesizer features synthesized sounds and waveforms as well as a micro drum kit with 16 punch-in effects including distortion, repeat, filters, fill-ins, glitches, and noise effects. The synthesizer parameters can be locked, while a 16-step sequencer, which holds 16 patterns in memory, can be chained into a song with up to 128 patterns. An integrated clock and alarm clock expand the creative possibilities of the instrument. A jam-sync function with 3.5mm audio in and out connections allows for multiple synthesizer units to be linked together.
Using high-quality components with low-power consumption, the synthesizer is cleverly designed with a Silabs EFM 32 Gecko CPU, a Cirrus Logic DAC, and a Knowles speaker placed under a novel animated LCD on a single circuit board. A foldout stand makes it easier to play and rear panel speaker solder terminals allow you hook up the unit to a larger sound system. An optional tailor-made silicone pro case (sold separately) adds anti-slip feet, battery protection, and professional-feel buttons to this very unique music-making device.
