CME WIDI K.O. II: The EP-133 K.O. II Goes Wireless!
Cables are annoying – especially in a portable setup. If you own a Teenage Engineering EP-133 K.O. II, you can now get rid of the spaghetti once and for all. CME, known for innovative wireless MIDI solutions, has announced a new WIDI adapter specifically for the K.O. II.
The WIDI K.O. II adapter plugs into the sampler’s MIDI jacks and perfectly matches the EP-133’s sleek design. The adapter is powered via MIDI and acts as a virtual MIDI cable, allowing you to easily connect the K.O. II wirelessly to other devices, such as the Teenage Engineering OP-XY, your DAW software on macOS, Windows, or Linux, or even mobile devices running iOS or Android. Sweet!
CME also offers WIDI adapters for conventional MIDI devices, allowing you to connect the EP-133 K.O. II wirelessly to any synth in your setup.
According to CME, the Bluetooth 5 connection has an ultra-low latency of only 3 ms. You can expect a range of about 20 m / 65 ft. A smart connectivity algorithm ensures stable plug-and-play connections with minimal interference, even in larger setups involving multiple devices.
The CME WIDI K.O. II is compatible with the Teenage Engineering EP-133 K.O. II and the EP-1320 Medieval.
Until October 31, 2025, you can pre-order the CME WIDI K.O. II from Thomann* at a special introductory price of $38 /£34 / €39. After that, the price will increase to $59. According to CME, the WIDI K.O. II will begin to ship on November 1, 2025.

Teenage Engineering EP-133 K.O. II Champions Update With Resampling and Much More!
[09 April 2025] A new firmware update is now available for the Teenage Engineering EP-133 K.O. II. Called the “Champions Update”, the compact sampler now comes with a number of new features that are sure to be on many a wish list.
This will surely please a lot of people. The latest firmware update for the Teenage Engineering EP-133 K.O. II includes some really cool new features. And they were definitely on the wish list of many users. Let’s take a quick look at the new features:
OS 2.0 provides resampling. A pattern can now be recorded with effects in a new sample. This means that a new sample can be created from sample stacks in combination with effects, which is of course an absolutely ingenious feature and gets even more out of the small sampler. What’s more, hands-free sampling is now possible, which means less finger acrobatics!
Just as cool, and at least as desirable, is the new Song mode. You can now link multiple scenes together to create a larger arrangement. There are 99 song positions, and combined with pattern lengths of up to 99 bars, it sounds very promising.
Sidechaining does exactly what it says on the tin. For example, it is now possible to lower the bass when a kick drum is played. This works via MIDI. And let’s stay with MIDI, because MIDI Thru is now also supported. Nice!
And somehow it’s funny that this wasn’t one of the features from the beginning: polyphony has been increased! With the OS 2.0 update, the Teenage Engineering EP-133 K.O. II can now play 16 mono and 12 stereo sounds simultaneously. You can’t believe your eyes! But yes, that’s exactly what it says on the website. As a reminder, before there were 12 mono and 6 stereo voices.
There are also larger note intervals, improved pitching for the sounds and a few other minor improvements that also improve the workflow. In short: a really good update that Teenage Engineering has given us so close to Easter. It makes the little sampler even better. A big thank you for that!

Teenage Engineering EP Sample Tool
[21 March 2024] The Teenage Engineering EP Sample Tool is a free web application that makes it easy to keep your samples organized on the EP-133 K.O. II sampler. Drag&drop samples from your computer to the device and vice versa, all from the comfort of your web browser.
The new EP Sample Tool from Teenage Engineering is a free browser app that makes short work of importing and exporting samples to and from the EP-133 K.O. II. The app recognizes the sampler when it’s plugged in and gives you easy drag&drop access to its memory. You can import and export samples, rearrange them in memory, and even trim the sample start and end points. Neat!
The Teenage Engineering EP Sample Tool is available free of charge on the manufacturer’s website. Unfortunately, though, it appears that it only works in Google Chrome as of now.
The EP-133 K.O. II is available from Thomann*.
EP-133 K.O. II
[22 November 2023 / Robin Vincent] This is certainly one heck of an upgrade over the original Pocket Operator. The PO-33 K.O! was a palm-sized, stripped-back micro sampler with 40 seconds of sample memory and a frantic interface for under one hundred pounds. The EP-133 K.O. II, while following a similar format, looks to be from some other planet, it’s much bigger than you think, and I have to say, it’s pretty stunning. It evidently blends a lot of different Teenage Engineering vibes. It has the opulence of the OP-1 screen and the precision of the TX-6 and TP-7, yet the Pocket Operator’s fun still shines through.
The design and layout are top-notch, everything we expect from T.E. But there’s also an abundance of controls, a generosity in the front panel that’s not as typical. At the time of writing, all I have is a photo and some specs, and I am seriously intrigued.
So, what do we get?
EP-133 K.O. II is a mobile sampler, sequencer and composer. That combination of features is probably what we’d usually call a groovebox. There’s an integrated microphone and speaker and a teeny weeny 64MB to sample into. It can handle 6 stereo or 12 mono voices and has room for 999 individual samples. It samples in 46.875kHz(?) and 16-bit with 32-bit internal processing.
It deals in Projects where each of the nine available Projects can contain 80,000 notes. These are managed through Patterns in Groups of four, where a Pattern has 12 tracks for samples and MIDI. All controls can be recorded and automated, with or without looping.
The numerical pads are pressure and velocity-sensitive with polyphonic aftertouch. They can be used to trigger samples and also drop in effects. There are six built-in send effects and a master compressor.
On the physical connections front, you get a 3.5mm stereo input and output, sync in/out, MIDI in/out and USB-C. 4x AAA batteries can also power it.
It is super thin and super lovely to look at with a sumptuous screen that, at the moment, I’ve got no clue what it does. I imagine all will become clear as soon as this launches.

Needs resampling
Wonder if it is possible with a firmware update?
I wish I could sample in while hearing the track playing …. Tall ask – but, if I wanted to sample myself playing keys/synths and stack layers to build a track I would need to play each layer with the song in my head from memory – the rearrange/chop to fit- I get that that is how most samplers work – just would like more live sampling options where I could hear the track to play parts along to
Are we able to record the punch in effects is my biggest question??????
But I don’t understand what’s new. This web sample tool is available from the day of release of the EP-133 K.O. II.
Hello, I did see the newsletter featuring this tool, and then this piece of news. Honestly this tool has been available since the release of the machine I cannot understand the value of this news and the hype. Sorry.
“As a reminder, before there were 12 mono and 16 stereo voices.”
You mean 12 mono and *6* stereo voices,,,
Thanks! typo… 😉 corrected.
