Description
Quick Summary
The Teenage Engineering PO-33 K.O! is a compact micro sampler and sequencer designed for fast sampling, beat making and portable music production. It lets you capture sounds through the built-in microphone or 3.5 mm line input, then sequence, edit and process them with effects and parameter locks.
With 40 seconds of sample memory, 8 melodic sample slots and 8 drum slots, the PO-33 makes it easy to turn almost any sound into a playable instrument or beat.
What Makes the Teenage Engineering PO-33 K.O! Special?
The PO-33 is built around instant sampling. Record a voice, instrument, record, phone, synth or everyday sound, then use melodic mode to play samples chromatically or drum mode to divide material across the trigger keys. This makes it equally useful for melody creation, drum programming and experimental sound design.
Its sequencer adds parameter locks, a step multiplier and 16 effects for hands-on pattern manipulation. Effects include looping, octave shifts, stutters, scratch-style effects, reverse and retriggering, making the PO-33 particularly effective for creative live performance and beat manipulation.
Who Is It For?
The PO-33 K.O! is ideal for beat makers, electronic musicians, producers and samplers looking for a compact hardware instrument that makes it easy to capture and transform sounds.
It is particularly well suited to hip-hop, lo-fi, electronic music and experimental production, while its pocket-sized design makes it a useful travelling sampler or addition to a wider Pocket Operator setup.
