I just got it so I haven’t had too much time with it, but so far this thing is exactly what I was looking for. It is set up so you can make music instantly and easily. I am not in the music industry and have no experience making music with a sampler other than a few attempts at the KO pocket operator. I tried the SP-404mkii but it was way too daunting to figure out for me (and the velocity pads on mine were defective). However, this thing is set up so you can start jamming as soon as your turn it on and it’s simple enough for beginners.As with any teenage engineering product I’ve bought, it can do way more than I expected and I look forward to learning more about it. I have an OP-1 I intend to connect this to once I play around with it more. The TKO ii is more user friendly than the OP-1 in my opinion.I had no issues with the Fader but I babied it while attaching the knobs knowing it was an issue for some. Hopefully they have just corrected it. I sprang for it knowing some reviews were bad and I don’t regret it so far. I’ll update if anything changes.

Just received my EP 133 in the mail. It took about a week to deliver to South East US. I'll start by saying this is not my first TE product. I own a few Pocket Operators, an OG OP-1, and a TX-6. One thing you should know about TE, that even though "Engineering" is in their name, their products aren't always 100%, and this usually causes a lot of frustration with people. Including myself. With my OG OP-1, I had to return it 3 times because of keys re-triggering. Overall, it's a design flaw, and not a one-off issue.With the EP-133 I read many reviews stating the fader knob was delicate, and could come defective. Happy to report that is not the case with my unit. It works flawlessly. I've also seen people state putting the knobs on the fader is hard, honestly, it's not, and just be gentle squeezing it in. It's basically a LEGO piece with a star socket. Just don't jam it on there, wiggle it until it slides on. It's also not meant to go all the way in. There is a stopper on the protruding stick where the knob goes. The rest of the knobs are smooth and easy to install.Going to play with it for a bit and maybe update this review. But like all TE products, these are not for everyone. There's a niche, and most of their products require a certain level of organic creativity. Hope those reading this and make the decision to buy aren't burnt with defective units. Just be gentle.

The fader. It sticks out, kinda like a sore thumb. And it loses its rigidity quickly. I'm talking wiggly after month one. Even after obtaining an A**log Case for light transport.Other than the fader, I love this thing. This feels like what the Pocket Operators were always aiming to become. It's fun and the keys are insanely Tactile.But there needs to be a KO II.2 that fixes the flaw with the fader. Cause we all saw the vision but it didn't work out.

Great fun to use, chromatic octave in 12 keys is great for transpositions, keys are quick, with far less pressure than most minisynths. A joy to play with. The earlier hardware issues seem to be dealt with.

After debating weather to get the original K.O., I recently discovered the K.O. II and started to look into it some more as I had been interested in a proper sampler and not just use my Casio SK-1 or Yamaha VSS-200.After reading about the complaints regarding the fade slider having issues, I decided to bite the bullet. The price wasn’t terrible and I figured I’d get it because my electronic capabilities would be sufficient to replace the slider if needed.I got the sampler and I have to say that the packaging looks great. It instantly invokes the thought of a record LP. My wife was even surprised at the packaging, as it did not look like a synth package.Opening the package was a challenge. That thing is in there extremely snug. There are finger holes to remove the sampler but if you tug too hard you will probably rip the outside sleeve. I gently shook it out on my bed with my finger guiding it.So far my biggest complaint stems from the packaging. While beautiful and extremely functional, it may be too functional. Like an IKEA box, no space was wasted, and this led to the curiosity of why Teenage Engineering shipped this without the knobs attached on the slider and pot.Not attaching the knobs only saves about 1/4” of space and they surely could have made the box bigger to account for such dimensions. I would think this might alleviate some of the issues people have had with the knobs, as I have read it may stem from people attaching them to firmly but as I opened the box, I also noticed marks on the inside where the packaging rubbed against the knob less pots and slider. I am sure that any good hit or jostling could potentially cause some damage, like when you ship a Faberge egg with zero packing peanuts.I followed some YouTube video suggestions carefully, such as gently attaching the knobs and when it came to the slider, not pushing it all the way down and attach the knob while the slider is positioned all the way up or down. I did notice the knob on the slider was a bit harder to get on than the volume or BPM knobs.The unit itself feels well built and while the buttons are plastic, the tapping seemed alright and played into the retro aesthetic. The lights and display are very intuitive and the inner packaging has a quick start cheat sheet. I wish there was a heavier duty instruction manual but I knew going in that probably wasn’t going to happen knowing Teenage Engineering. I was able to start making my own sound bank within 5 minutes.So overall, I feel this thing is worth the money. Who knows. Firmware updates in the future may resolve some issues and if they do a revision on packaging or components you might be able to get this one at a good price, although I doubt it as their products seem to hold value really well.…and after a thorough testing the fader is broken out of the box. Does not respond one bit. Looks like this will be returned and while the sampling and use seemed easy out of the box, what good is it if this is faulty from the beginning?!

Real cute, love that it has a mic and speaker so you don't need to anything else to use it. That said, no resampling? No arpeggiator? Only one effect at a time, to the whole group? It's just not worth it - and beyond that, it's so lacking it feels like a waste of time to learn it in a deep way. Menus are a deep dive, interface is not at all intuitive. For $400 it's a really expensive toy, but it doesn't feel like a true instrument. Gimmicky. Disappointing.

Watch some reviews and tutorials before purchasing to get the full sense of how capable this piece of tech is— a decent midway between all of TE's instruments. It's not a "must have" device, but worth it for the experimental aspect.

I said what I said.

Chegou em perfeito estado e em menos de 20 dias recomendo

Me encanta mi nuevo juguete. Está bien hecho y es muy intuitivo. Empiezas a hacer música desde el principio. Es liviano y portátil y, después de un largo día frente a la computadora, es fantástico tener algo con lo que puedas sentarte en un rincón y jugar.

Fonctionne super bien, idéal pour arriver rapidement à des bonnes sonorités.En revanche est arrivé avec le cache qui ne tiens pas en place, c’est domage…

Der EP-133 KO II ist ein echtes Biest, wenn es um kreatives Sounddesign und spontane Ideen geht! Die Sampling-Funktion ist so einfach wie genial – ich kann direkt alles aufnehmen, was mir in die Ohren kommt, und es im Handumdrehen in Beats oder Melodien verwandeln. Besonders stark finde ich, wie intuitiv das Ganze aufgebaut ist: Kein langes Einarbeiten, sondern einfach direkt loslegen und experimentieren.Trotz seiner Größe steckt erstaunlich viel Power drin: Der Sound ist fett, die Effekte vielseitig, und das Sequencing bietet genug Tiefe, um komplexe Patterns zu bauen. Vor allem live bringt der KO II richtig Spaß, weil man ihn so dynamisch spielen kann. Perfekt für spontane Jams oder als Ergänzung zu anderen Geräten wie dem OP-Z.Einziger Kritikpunkt: Die Bedienoberfläche ist bewusst minimalistisch gehalten, was für Einsteiger anfangs etwas gewöhnungsbedürftig sein kann. Aber wer dran bleibt, wird belohnt – und zwar mit einem Gerät, das den kreativen Flow einfach nur pusht. Für mich ein Must-Have für kreative Musikproduktion!
