Teenage Engineering EP–133 K.O. II 128MB Sampler

EP–133 K.O. II Sampler — From Idea to Track in Real Time

The Teenage Engineering EP–133 K.O. II 128MB is a portable sampler, sequencer and composer built around a fast, hands-on workflow. Record sounds through the built-in microphone or stereo line input, slice them live, and arrange patterns across four groups of 99 bars each. This unit is the right choice for producers who want a tactile, battery-powered groovebox for any setup.

What Makes the K.O. II Stand Out

The punch-in 2.0 effects engine is pressure-sensitive and lets performers mangle sounds in real time using the pad grid and the assignable fader. The super-segment hybrid display, the first of its kind, gives visual feedback for sequencing, sampling, and parameter editing without menus.

Tech Specs That Matter for Beat Making

Sampling engine, sequencer architecture, and I/O define what this unit can do in a session.

• Sample Memory: 128 MB — roughly 40 seconds of stereo audio at 16-bit / 46 kHz across 999 sample slots
• Voice Polyphony: 12 stereo / 16 mono voices with a 32-bit float internal signal chain and 24-bit ADC / DAC
• Sequencer: 9 projects, 4 groups × 99 patterns, 12 tracks per pattern — song mode up to 9,801 bars
• Twelve pressure- and velocity-sensitive keys with 50 gf operating force and PA66 polyamide housings
• Effects & I/O: 6 master send FX, 12 punch-in FX, master compressor, sidechain — plus USB-C, TRS Type-A MIDI in/out, analog sync in/out, and 3.5 mm stereo line I/O

Who This Sampler Is Built For

The K.O. II fits producers who want a tactile alternative to mouse-driven DAW sampling. Hip-hop beatmakers, lo-fi producers, and live performers can capture, chop, sequence, and effect sounds without booting a computer. Beginners get a curated pre-loaded sample library, while experienced producers get a portable sketchpad that runs on AAA batteries anywhere inspiration strikes.

From Pocket Operator to Desktop Champion

Building on the legendary PO-33 K.O! pocket operator, the K.O. II expands the same sample-and-sequence philosophy into a desktop unit with more pads and memory. The 128 MB version doubles the original 64 MB capacity.
