Small enough to fit in your pocket and powered by a pair of AAA batteries, the Teenage Engineering PO-16 Factory Synthesizer features multiple real synthesizer engines including FM, subtractive synthesis, wave table, and physically modeled strings with 16 punch-in effects including delay, bit crusher, and filters. It also includes 16 punch-in arpeggio and chord playing styles. The punch-in play styles are a quick way to create melodies. The concept is to minimize the effort of entering a complete series of notes in a sequence by simply adding one or a few notes and then allowing the punch-in function to fill in variations of the notes that follow.

The synthesizer parameters can be locked while an auto compressor and hardware limiter ensure adequate signal generation without clipping.

A 16-step sequencer features 16 available patterns and up to 16 patterns can be chained together. An integrated clock and alarm clock expands 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 fold-out 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.
