The EP–133 K.O. II Just Levelled Up
Teenage Engineering’s EP–133 K.O. II already made waves for packing serious sampling and sequencing power into a super‑portable form factor. With the latest hardware revision and OS 2.05 improvements, the K.O. II is more capable, more stable, and more fun than ever—perfect for beatmakers, sound designers, and musicians who want to create anywhere, anytime.
Whether you’re recording the sounds around you, chopping samples, building sequences, or turning quick ideas into full tracks, the EP–133 is designed to keep you moving fast and staying creative.
Bigger Sample Memory, Bigger Ideas
One standout upgrade: expanded sample storage of 128 MB.
That’s double the previous capacity and a huge boost for artists who like long takes, detailed textures, or bigger sample libraries. More room means more creative freedom—without needing to constantly delete older sessions.
Record, Resample, Sequence — Fast
The K.O. II is built around fluid, hands-on workflow:
✔ Built‑in microphone + speaker
Capture quick ideas or spontaneous sound moments anywhere.
✔ Record and resample with effects
Shape your samples with filters, pitch shifting, and characterful FX.
✔ Pressure‑sensitive keys + multifunction fader
Perform with dynamics, tweak parameters, and automate movements in real time.
✔ 12 stereo / 16 mono voice polyphony
Surprisingly deep layering possibilities for such a compact device.
✔ Punch‑in FX + 6 master FX
Instant fun, quick moments of chaos, and fast transitions during performances or sketching.
A Pocket-Sized Production Hub
The I/O options are impressive for something this small:
- 1× stereo input / output

- USB‑C power and data
Whether you’re integrating with a DAW, jamming with hardware, or sampling vinyl, the EP–133 connects without hassle.
Power it via USB‑C or 4× AAA batteries—ideal for travel, couch sessions, and outdoor sampling.
Song Mode: Your Track, Your Way
Scenes can be chained together for full arrangements. Build your sections, transition between patterns, and quickly structure an entire track straight on the device—no computer required.
Stereo Effects, Sidechain + Automation
The K.O. II lets you treat samples like a true instrument:

- sidechain pumping for instant groove
This is where the unit truly shines: fast, tactile, and endlessly tweakable.
