The lead-synth entry in Teenage Engineering's Pocket Operator line, packing multiple real synthesis engines — FM, subtractive, wavetable, and physically modeled strings — into a credit-card-sized, batteryless-looking circuit board with no housing. Sixteen punch-in effects and sixteen arpeggio/chord play styles let melodies build themselves with minimal manual note entry.

A Silicon Labs EFM32 Gecko processor and Cirrus Logic DAC drive a hidden Knowles speaker beneath the animated LCD screen, and a jam-sync function over 3.5mm audio lets multiple Pocket Operators (or other synced gear) play together.
