The Teenage Engineering Pocket Operators are highly popular devices — pocket-sized synthesizers packed full of exciting sounds and rhythmic options. They’re also remarkably affordable.

The beloved series of pocket-sized instruments reaches its 10th birthday ... the PO-14 Sub bass synth and the PO-16 Factory, ...

For a pocket synthesizer this has a lot to offer, even if you plan on using it as something else entirely thanks to the versatility of the Cortex M3.

Inside there’s a full subtractive synth engine, and space for 12 presets. Editing can be handled by connecting the Minichord to a computer over USB and opening up the web-based interface.
