    Teenage Engineering EP-133 K.O. II: A Knockout Redefinition of the Sampler

    The sampler that started a movement just hit Round II — and it didn’t come to play nice. The Teenage Engineering EP-133 K.O. II is the evolution of the cult-favorite PO-33 K.O.!, rebuilt from the circuits up to deliver a full-blown, stage-ready music workstation. Still small enough to fit in your backpack, but now packed with heavyweight features like velocity-sensitive pads, punch-in 2.0 effects, a high-res sequencer, and fader automation that would make a DAW blush.

    This isn’t a sampler. It’s a sampler, sequencer, composer, MIDI controller, and full-blown chaos machine all rolled into one beautifully minimal slab of gear. The EP-133 K.O. II turns sound into weaponry — letting you slice, mash, and mutate samples with freakish speed and precision. It’s the most musical piece of plastic you’ll ever fall in love with. And yes, it punches way above its weight.

    Teenage Engineering EP 133 KO II Twelve Pressure Pads

    A Tiny Box Full of Ridiculous Power

    Teenage Engineering's EP-133 K.O. II might look cute, but don’t be fooled. Whether you’re sketching beats on the couch, slicing loops mid-set, or crafting a 10-minute experimental odyssey, the KO II gives you the tools and the freedom to do it your way.

    • 12 Pressure- and Velocity-Sensitive Pads: Dynamic, expressive performance control — play it soft, smash it hard, and everything in between.
    • Record + Automate All 12 Fader Assignments: Real-time tweaking with instant automation. Filter sweeps? Pitch drops? MIDI chaos? All fair game.
    • 9 Projects, 80,000 Notes Each: Let that sink in. You’re not running out of ideas — you’re just running out of excuses.
    • Patterns, Groups, and Song Mode: 4 groups per project, 99 patterns per group, and 12 tracks per pattern for samples or MIDI. Build full songs, live sets, or abstract rhythmic art — you do you.
    • Variable Pattern Lengths + Loop Mode: Per-group pattern lengths (1–99 bars) and OB-4-style loop sliding for ultimate groove control.
    • Live + Auto Sample Slicing: Chop samples in real-time or let the machine do the dirty work.
    • 6 Send FX + Master Compressor: Shape your sound with onboard reverb, delay, distortion, and more. Then glue it all together with a fat compressor.
    • Punch-In FX 2.0: Trigger real-time effects with pressure sensitivity — ideal for live manipulation and general sonic mayhem.
    • High-Resolution Sequencer with Swing + Quantize: Stay loose or lock it in. Swing it however you want, the EP-133 K.O. II doesn’t judge.
    • 46.875 kHz / 16-bit Sampling + 32-bit Float Signal Chain: Sounds clean, hits hard, and leaves your WAVs smelling like vinyl.
    • Drag-and-Drop Sample Tool: Transfer samples fast and get back to the music. 

    It’s modular-level creativity in a device that’s portable enough to throw in a gig bag without sacrificing an inch of capability. That's about as cool as it gets.

    Get Yourself a Full-Fledged Workstation

    Don’t let the minimalist look fool you — the EP-133 K.O. II is a creative control center disguised as a sampler. Thanks to a full range of I/O — including USB-C, MIDI in/out, sync in/out, and stereo audio connections — the Teenage Engineering EP-133 K.O. II acts as a flexible hub for whatever setup you’re running. 

    Hook it up to your drum machines, synths, grooveboxes, or DAW, and you’ve got full sample sequencing, MIDI control, and live performance FX all in one compact unit. It even supports external sync at 8th, 16th note, or Sync24, so you can lock into just about anything with a pulse. And when it’s time to move from your studio to the stage? Just unplug your cables and go.
