Musician builds awesome Arduino-powered MIDI controller, and so can you

DIY Arduino MIDI Controller - The MIDI Machine
Making music can be an expensive hobby, particularly if you don’t set limits on the equipment you’re willing to shell out for.

That’s the fate musician Alex Coover, aka Glacial Geyser, came close to experiencing when he set out to get his hands on a new piece of musical equipment. Or, rather, it’s the fate that certainly would have befallen him if he didn’t turn out to be so darn good at DIY projects.

“The keyboard that I use to write music doesn’t have a pitch bend or modulation wheel,” Coover told Digital Trends. “I started looking on the internet for a stand-alone unit and I couldn’t find anything that fit what I was looking for. It seemed that what I was searching for simply didn’t exist unless you were willing to buy a whole new keyboard. I didn’t want to spend that kind of money, so I started considering building my own.”

Jump forward in time, and Coover is the new, proud owner of a homemade, DIY, Arduino-powered MIDI controller, which he calls the Midi Machine.

“I’d never used an Arduino before, and nor I had done too much with soldering other than a few repairs on things I already owned,” he continued. “I enjoyed [the project], although doing the programming for the Arduino was the part I felt most lost on!”

It seems to have been a worthwhile endeavor, however, because the finished product doesn’t just contain pitch bend and modulation wheels, but also two 75mm 10k faders, 10k knobs, and a nifty splattered paint effect for good measure.

“I’ve heard from a lot of people who want to do something similar,” Coover said, regarding the feedback he’s received regarding his homemade instrument. “Most of them have very supportive — although I’ve heard from a few people who tell me I should’ve been using 3D printing. They were disapproving of the fact that I did this by hand, and that I was being such a caveman about cutting out pieces of plastic myself!”

While Coover had to experiment to build his MIDI Machine, however, he’s made it easy on other budding musicians by detailing the step-by-step instructions on an Imgur page, which makes the whole process as easy as learning a new guitar chord.

As for Coover, he told us that the completed MIDI controller has turned out every bit as well as he hoped.

“I’ve been using it every day since I finished it,” he said. “With this controller, I can use it as a drum machine, as well as using the knobs to add effects. At some point in the next couple of years, I want to release a new album — using this as a key instrument in the production.”

We’re confident it’ll be worth the wait!

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."
