Molten Music Technology’s Robin Vincent dives headfirst into the Neutral Labs Luna—a Lunetta-inspired box of sonic chaos that’ll have your patch cables in a twist. This isn’t your average solder-and-play kit; it’s a proper challenge, full of oddball components and instructions that read like a cryptic treasure map. Robin’s signature blend of dry wit and hands-on honesty makes the journey as entertaining as it is educational. If you’re keen on unpredictable noise machines and don’t mind a bit of sweat and solder, this one’s for you, mate.

Molten Music Technology Gets Loony: Building the Neutral Labs Luna Synth
Luna: Synth Oddball in a Box
Molten Music Technology kicks things off by introducing the Neutral Labs Luna, a synth that’s as far from vanilla as a kangaroo is from a city tram. This isn’t your standard bleep-bloop machine—it’s a Lunetta-based beast, paying homage to Stanley Lunetta’s logic-chip experiments from the 70s and 80s. The Luna’s all about metallic screeches, gritty textures, and sounds that’ll make your neighbours question your life choices.
Robin’s first impressions are a mix of curiosity and mild confusion, which is exactly what you want when facing a synth designed to break the rules. The Luna exposes all its ins and outs on the front panel, inviting you to build your own temporary musical computer. If you’re after polite, predictable tones, look elsewhere—this box is for those who like their sound design with a side of chaos and a dash of unpredictability.
"The Luna, as far as I can work out, is some kind of weird mystical synthesizer that nobody ever thought of before."

The Build: Soldering Mayhem and Bag Roulette
Jumping into the build, Robin finds the Luna kit lovingly bagged but the instructions about as clear as a dust storm at dusk. Each step is a new adventure—sometimes you’re hunting for the right bag, other times you’re wrestling with components that seem to have a mind of their own. The manual’s conversational style is charming but leaves plenty of room for head-scratching and the occasional soldering mishap.
The process is intricate, with a mountain of patch sockets, pots, capacitors, switches, and LEDs to wrangle. At times, it’s like herding emus—especially when trying to keep everything aligned for the front panel. Robin’s patience is tested by the lack of photos and bullet points, but he powers through, offering plenty of real-world tips and a few laughs at his own expense.
This is not a kit for the faint-hearted or those who want instant gratification. Expect to spend hours soldering, double-checking, and occasionally muttering under your breath. But if you love a challenge and don’t mind a bit of chaos, the Luna rewards you with a sense of accomplishment that’s hard to beat.
Deep Dive: Features and Creative Potential
Once assembled, the Luna opens up a playground of sonic possibilities. Robin gives us a guided tour of the synth’s layout—five oscillators, a mixing section, low pass gates, effects, and a quirky interface that encourages experimentation. The design is unapologetically weird, inviting you to patch, tweak, and discover new sounds with every session.
The Luna’s creative potential is massive for those willing to explore its labyrinthine logic. It’s not about instant hooks or polished presets; it’s about getting lost in the noise, finding happy accidents, and embracing the unpredictable. If you’re the type who loves twisting knobs just to see what happens, this synth will keep you entertained for ages.
Live Testing: Embracing the Chaos
"The beautiful thing about Neutral Labs boxes is that they are in many ways incomprehensible but also experimental and fascinating and absorbing and glitchy and crazy."

Robin puts the Luna through its paces in real time, and the results are as wild as a BBQ gone wrong. The synth spits out glitchy rhythms, metallic drones, and unpredictable sequences—sometimes behaving, sometimes going off the rails. It’s a hands-on demonstration of the Luna’s experimental soul, with each patch leading to new sonic territory.
Watching the Luna in action is a reminder that some things just can’t be captured in words. The real magic is in the unpredictable interplay of logic circuits and patch cables—something best experienced with your own ears (and maybe a fire extinguisher handy). If you want to hear the Luna’s full madness, you’ll have to check out the video for yourself.
Build Reflections: Tips and Room for Improvement
Robin wraps up with some honest feedback on the build process. While the Luna kit isn’t impossible, it could be a lot smoother with clearer instructions, more photos, and a step-by-step approach. Soldering the entire front panel in one go is a recipe for frustration, and breaking the process into smaller chunks would make life easier for everyone.
He suggests that including a specialised tool for tightening nuts and a more structured manual would turn the Luna from a soldering slog into a more enjoyable project. Still, the sense of achievement at the end is real, and the Luna’s wild, experimental character makes the effort worthwhile for any synth nut who loves a challenge.
"While I quite like the conversational approach, it's not very... it doesn't lend itself to trying to do something which is quite difficult."
