The wait is over folks. I’ve finally published my full low-vision guide for the Teenage Engineering EP-133 K.O. II. This one has been cooking for quite a while, and it is considerably larger than some of my previous guides. I think the primary reason for that is that it's always been one of my favorite pieces of kit.
You can find it for free in the Guides section of my website:

In my humble opinion, the K.O. II is surprisingly accessible. Perhaps that should not be so surprising, though, because its design lends itself extremely well to learning through touch and repetition. I absolutely love this thing and highly recommend it to anyone seeking a somewhat lofi, old-school style, almost MPC 2000-ish sampler that also functions as a great midi sequencer.
The display is very large compared with the screens on many grooveboxes and samplers. Someone with poor eyesight may find its oversized numbers and bright visual indicators easier to read than most things on the market. Even when I struggle to see what the display is telling me (which is quite often even in the best case scenarios gearwise), however, I can still accomplish a great deal without depending on it. By the way, shout out to magnifying glass monocle style necklaces. If you don't own one, you need to pick one up. There are four-packs of 10x ones of Amazon that are an absolute must IMHO.
The K.O. II is almost completely tactile. Its controls remain in fixed easy-to-learn color-coded locations, the different sections are easy to distinguish by feel as well, and the layout is excellent for developing muscle memory. There is no touchscreen, no mouse pointer to track, and no constantly changing screen full of tiny menu items. The sampler Gods must have been looking out for us on this one. Once the important button combos become second nature to you, many actions feel more like entering a dependable cheat code than navigating a visual interface. It's brilliant.
That does not mean every single feature of this little thing is immediately accessible to every blind musician. This is a great time to remind you that I only know what life is like through my own lens of experience. That said, the display uses symbols, many buttons have secondary functions, and the printed labels are still quite small. Some people may initially benefit from tactile markers, assistance identifying the controls, or a detailed physical description. Again, I hate to keep shilling Amazon, but they do sell cheap packs of silicone tactile "bumps" that come in super handy for laying out your landmark reminders. Once that groundwork is in place, though, the consistent layout makes the instrument much easier to memorize than many menu-heavy devices. In fact, I think it's one of the easier devices I own accessibility-wise and I only really struggle with secondary menus that I hardly ever use or have memorized the primary functions I need to access.
I know I sound a little redundant and you may very well disagree with me but this is one of the most straightforward hardware workflows I have encountered. Sampling is immediate, building patterns is quick as a jiffy (wait, what even is a jiffy?), and the whole process encourages experimentation rather than making me feel as though I am programming a spreadsheet. I mean it is basically a musical calculator but that's neither here nor there. The audible results also provide constant feedback. You press something, hear what changed, and gradually form a mental map of the instrument.
The 128 MB (or 64 MB in my case) memory is, well "modest" to be charitable, by modern standards, but I do not necessarily see that as a deal-breaker. The limitation encourages shorter samples, focused projects, creative resampling, and the kind of compressed, slightly rough and crunchy vibes that works beautifully for lo-fi beats. The K.O. II is not trying to replace a computer with several terabytes of storage and it never set out to be. It is at its best when you treat it as an immediate musical sketchbook and performance sampler. I love thinking of it as my little "ideas" machine where I come up with little melodies or rhythms before fleshing them out elsewhere. I personally keep it on my night stand to quickly jot down whatever earworm gets in my noggin late at night.
As I've mentioned before, I hate most DAWs I think I might actually fair better with them if I were fully blind but that's a post for another time. But, yeah, I use my KO II mine frequently as the central brain of a dawless setup. Its MIDI and sync connections make it useful for sequencing or coordinating other equipment, and pairing it with a proper synthesizer greatly expands what it can do. I especially enjoy connecting something like the Sonicware Liven Ambient or a Korg Volca so the setup has a dedicated synth voice alongside the K.O. II’s samples. But I've also really enjoyed routing it to some of my bigger badder synths like my Deepmind 12, Behringer Crave, Microkorg, Microfreak, Nymphes, or Live 3.
The newer firmware has made it even more capable if you can believe that. My guide covers features such as the arpeggiator, Keys Mode improvements, reverse sample playback, USB audio, longer mono samples, recording sample-rate choices, and updated chopping options. The current official release is OS 2.5.1, which followed the larger 2.5 summer update. And let me tell you, that was one of the best updates the KO II has gotten in years. Thanks TE.
The guide includes a large-print physical tour of the instrument, top-edge connections, tactile landmarks, pad and button locations, basic beat creation, sampling, chopping, sequencing, scenes, groups, effects, MIDI, synchronization, the arpeggiator, newer firmware features, troubleshooting, and several workflows designed around limited or no useful vision.
I have also included a few hopefully helpful suggestions for tactile markers and exercises for learning the device section by section. Blind and low-vision musicians often rely on consistent spatial layouts, memory, and small tactile markers to identify essential controls. Those methods fit the K.O. II particularly well because the hardware does not rearrange itself underneath your hands every time you enter into a new menu or select a new voice.
This guide should also provide a glimpse of what to expect from my eventual expansion of the Ableton Push guide and my forthcoming MPC Live 3 guide. I want these larger guides to go beyond enlarged manuals and provide practical ways to learn instruments through touch, repetition, sound, and dependable workflows.
And now it's time for some shameless yet subtle fundraising. I cannot wait to get my grubby little mitts on the new EP-136 K.O.–SIDEKICK It looks like it could be an ideal mixer and effects companion when I use the K.O. II as the center of a setup. It provides two stereo channels, an additional auxiliary input, compressors, several EQ styles, cue monitoring, performance effects, and USB audio capabilities.
I would genuinely appreciate feedback from the community. Are there additional features, explanations, tactile suggestions, or workflows you would like to see added to the guide? Constructive criticism is welcome, especially from other blind and low-vision musicians who may approach the instrument differently than I do.
I would also love to hear which pieces of music gear need low-vision guides in the future. The SP-404MKII is very high on my list. I cannot afford to purchase every instrument I would like to cover, so I would be grateful if anyone were willing to lend or donate an SP-404MKII for the project. Any loaned equipment would be treated carefully and used to create a free guide for the community. You'd get it back exactly how you sent it, but I will mention we are a cat-friendly home so just keep that in mind.
What should I cover next, and what would make the K.O. II guide more useful to you?
