The PO-20 arcade features 16 synthesis-based video game, console and chiptune sounds, which are controlled via the built-in step sequencer.

The pocket synthesisers from the cult Swedish manufacturer Teenage Engineering have no casing, so all components and the circuit board are directly visible and form part of the design.

Power is supplied by 2 standard (AAA) micro batteries.

In addition, every Pocket Operator features an animated LCD display, a built-in speaker, a bent-wire stand, Jam Sync for synchronising with other devices, line in and out inputs (3.5 mm jack) and, conveniently, a built-in alarm clock.

Automations can be recorded per step using Parameter Lock.

Effects available include filters, bit crusher, delay and stutter, amongst others.
