Teenage Engineering PO-33 K.O. is a remarkably powerful pocket-sized sampler that fits in the palm of your hand yet delivers professional-grade sound quality. With a built-in microphone, 40 seconds of total sampling time, 16 sample slots (8 melodic + 8 drum), a 16-step sequencer, and 16 pattern memory locations, the PO-33 K.O. is designed for both spontaneous creativity and serious music production.
Record audio directly via the internal mic or through the 3.5 mm (⅛”) stereo input, then assign samples to 8 chromatic melodic slots for pitched playback or 8 drum slots for one-shot triggering. The intuitive 16-step sequencer supports parameter locks, swing, and real-time recording, allowing you to build intricate rhythms and melodies. Chain patterns together or switch them on the fly for dynamic, evolving performances.
Despite its miniature size, the PO-33 K.O. features a built-in speaker, fold-out kickstand, and runs on 2 AAA batteries for true portability. It syncs seamlessly with other Pocket Operators and compatible hardware via Jam Sync (audio pulse through the 3.5 mm jack). Whether used as a sketchpad, beat machine, or live performance tool, the PO-33 K.O. proves that big ideas come in small packages.
