  • Very Impressed
Color: EP–133
Playing the drums is fun. Playing guitar is fun. So why shouldn’t playing a sampler be fun? I’ve only had one evening with the EP-133 and I have already had more enjoyment with it than I have in 4 years of owning an SP-404SX. I tried for years to vibe with the 404 but it always lead to frustration. I thought if I gave it more time and practice it would click but I gave up and decided to try a new company. As a long-time Teenage Engineering hater I approached the EP-133 with skepticism but it really is as instantly fun and user-friendly as people say it is. Favorite aspects so far: the Punch-in effects and the display. The screen just looks awesome and the icons are really cool and fairly intuitive. I haven’t delved into sampling and deeper functions yet- made one beat and have been spending hours playing with the effects and learning the fader controls. The punch-in effects are so gd fun. Criticisms: I wish the enclosure was aluminum but the overall construction and material quality is very nice. I think people’s complaints about the durability come from the initial batch with the fader issue. I build cabinets and furniture professionally and guitar pedals on the side so I know craftsmanship when I see it. I think this thing is built to last. The potentiometers have a little wobble but it’s absolutely nothing compared to how bad the SP-404’s are. The pads on the EP-133 are very small, tightly grouped, very touch-sensitive and made of smooth plastic, not rubber- so accuracy is an issue. Final thoughts: Thing is friggin sweet. It’s so nice to sit down with a sampler and have fun for once. If you’re on the fence read the manual and if you see no real dealbreakers give it a try. Buy a used one and resell it if you don’t vibe with it. ... show more

  • An Instant Classic and Creativity Supercharger
Color: EP–133
As a longtime fan of Teenage Engineering's design philosophy, I had high expectations for the EP-133 K.O. II, and it has completely blown them away. This device is pure, distilled fun. It's a sampler that removes all the friction between having an idea and making a beat, and it has quickly become the centerpiece of my creative workflow. The Workflow: Immediate and Inspiring This is where the K.O. II truly shines. The workflow is incredibly fast and intuitive. From sampling a sound off my phone or its built-in mic to chopping it and sequencing a pattern takes literal seconds. The layout, reminiscent of a vintage calculator, is brilliant. Every button has a clear purpose, which encourages you to play and experiment rather than get lost in menus. The "commit" function, which duplicates your pattern and lets you build on it, is a genius way to evolve a track without losing your original idea. Sound and Performance: The K.O. II has a sound all its own—it's punchy, a little gritty, and full of character. It makes samples sound better just by being inside it. The real magic, however, happens with the live performance features. The "Punch-In FX" are absolutely incredible. Being able to add stutters, filters, and other effects on the fly is not only fun but a powerful tool for transforming a simple loop into a dynamic performance. The pressure-sensitive keys feel great for adding variation to your patterns. Design and Vibe: In typical Teenage Engineering fashion, the K.O. II is a design masterpiece. It's lightweight, durable, and the perfect size to throw in a backpack. Running on batteries and having a built-in speaker makes it the ultimate portable music-making machine. It's a device that begs to be picked up and played with, wherever you are. Conclusion: The EP-133 K.O. II is more than just a sampler; it's an instrument of inspiration. It's perfect for both beginners who want to learn the ropes of sampling and seasoned producers looking for a fun, fast, and powerful tool to capture ideas. It's one of the most enjoyable pieces of gear I've ever owned, and I can't recommend it highly enough. ... show more

  • My new favorite toy!(with an important message)
Color: EP–133
Let me preface this by saying I sympathize with everyone who received a faulty unit or damaged the fader when installing the cap. Teenage Engineering cannot sell a product with such a glaring design problem and poor quality control. At the very least they should have the fader cap preinstalled. Now despite that intro, I'm about to do a complete 180 and gush about this little machine. Having received it completely undamaged and opting to use a Lego pumpkin for the fader cap, I have felt nothing but overwhelming joy in the short time I've used the KO II. Having no experience with music production outside of playing around with FL Studio and my OP 1, the KO II is welcoming in its approach to beat-making and anyone can put together a solid track in no time. The illuminated icons and 8-segment display give me all the info I need without needlessly clunky menus, making the musical process feel intuitive. The preloaded sounds feel punchy and the onboard effects, while a little limited, have a lot to offer and don't even get me started on its sampling capabilities. The actual body of the device feels solid in the hand and all the buttons, dials, and slider have a good feel to them(assuming the unit passed QA before shipping). My only real complaint is that the onboard speaker is kind of faint, especially on the lower frequencies but I assume most of you are probably going to use headphones or some other audio output. In conclusion, I have high hopes for the KO II. According to the TE, this is the start of their new "EP" series and from what I've seen on the body it looks like there are Lego peg holes on both sides of the unit which leads me to believe there will be more of versions that can be connected to make an entire EP panel, but I'm getting ahead of myself. In an ideal world, I'd give this my full recommendation to anyone even slightly interested in music production. But the truth of the matter is it wouldn't be fair to everyone who was promised this magically little device and got a hunk of malfunctioning plastic instead. I hope this review does reach TE because I think its message resonates with the community; We love the idea but we're disappointed with its execution. ... show more
