Make the world your creative playground.

The teenage engineering EP–133 K.O. II is a powerful sampler, sequencer and composer. Record sounds around you, sequence your samples and loops, tweak and automate filter, pitch and more, add stereo effects, compressor and next-generation punch-in effects—go from idea to track faster than ever.

Get Ready for Round 2

Meet the next evolution of the world's most sold sampler. Based on the legendary PO-33 K.O!, the new EP–133 K.O. II adds more power, more sampling capabilities, a fully reworked sequencer and brand-new punch-in 2.0 effects. The EP-133 K.O. II introduces a workflow that lets you go from idea to track faster than ever. It's Pocket Operators gone pro.

The Champ Is Here

A versatile machine with an impressive set of features, K.O. II is the new champion in and outside the studio. Unrivaled by anything in its class, this is the sampler you've always wanted at an incredible value. Record sounds around you, sample your voice, favorite synths, vinyl records or whatever audio that you've got on your phone.

Sequence Your Samples and Loops

Make use of the curated selection of drums, bass and keys that come pre-loaded on your K.O. II. Tweak and automate things like filter, pitch and more ... add stereo effects, compressor and next-generation punch-in effects. The sequencer engine of the K.O. II provides an intuitive, fast way of building up beats and variations using four groups with 12 patterns each. Like most DAWs, you can instantly swap patterns per group, experiment with different combos to find what beat and bass lines work together. The commit button helps you freeze a point in time and move on, adding a verse or a break. It all happens in real time while playing.
