TL;DR: Cyma Forma, the French team behind the ALT drone synth, has teamed up with artist Bambounou to create the RND — a one-button, multi-layer random synthesizer that generates over 4 billion unique sounds with no saving, no tweaking, and no presets. It’s a deliberate anti-workstation that forces you to stop playing and start listening, and we at Noxal are both terrified and intrigued.
- One big black button triggers a four-layer sound built from eight synthesis engines (subtractive, FM, acid, noise, speech, Karplus-Strong, supersaw, additive) — no two presses are the same.
- No sound saving, no editing on the hardware — you press, you get a sound, you lose it forever. Over 4 billion possible sounds, all generated on the fly.
- USB-C audio transmits all four pre-reverb layers independently, plus four MIDI channels with nine control modes; analog sync and MIDI clock in/out are included.
- Pre-orders open at €125 + VAT, shipping starts late June 2026 — and at that price, we’re already wondering how many coffee beans that could buy instead.

The Anti-Synth Philosophy
Let’s be honest: most of us spend more time tweaking knobs than actually making music. We at Noxal are guilty of this — I once spent an afternoon dialling in a filter sweep on a Monologue while my coffee went cold and my inspiration evaporated. The Cyma Forma RND is a direct rebuke to that behaviour. It’s a one-knob machine that says, “Stop playing, start listening.” And by “one knob,” they mean one big black button.
The RND is a collaboration between Cyma Forma (founded by two Vincents, which sounds like a French art film) and French artist Bambounou. The idea is dead simple: you press the button, a random sound emerges. You press it again, a new sound. None repeat. None can be saved. Each press is a fresh sonic universe that vanishes into the void the moment you hit the button again. It’s like doom-scrolling for sounds, and I have to admit — I pressed it a lot at SynthFest France 2026. It’s addictive in the way a slot machine is addictive, except the payout is a four-layer, multi-synthesis patch instead of a jackpot.
This is not a synthesizer for control freaks. It’s for people who trust the machine. And honestly, after years of menu-diving and patch-cable spaghetti, that’s a breath of fresh air. Or maybe we’re just getting old and lazy. Either way, the RND is a deliberate anti-workstation — and we respect that.
Inside the Random Engine
Under the hood, the RND is a digital multi-timbral synthesizer that builds each sound from four layers. Each layer is drawn from one of eight synthesis engines: subtractive, FM, acid, noise, speech, Karplus-Strong, supersaw, and additive. That’s not just a random selection — each instrument has its own “musical DNA,” as the developers put it. The result can be a sequence, a one-shot, or a drone, and the engine also includes a sound mixer, five filter types, and various modulators.
What’s remarkable is that these aren’t pre-designed presets or samples. Each sound is generated from scratch, and Cyma Forma claims over 4 billion possible combinations. My expectations were low — with random, you usually get a lot of noise and unusable garbage. But I pressed the button more than ten times at the show, and every single sound was melodic and usable. It’s like the synth has a built-in sense of taste, which is more than I can say for some of my own patch designs.
The engine also includes 20 musical scales to keep everything in key, so you’re not just getting random notes — you’re getting musically coherent randomness. It’s controlled chaos, and it works.
Hardware and Connectivity
The RND hardware is compact — which is obvious when the only control surface is a single button. But it’s surprisingly well-connected. The USB-C port handles audio and MIDI, transmitting all four pre-reverb audio tracks independently. That means you can record each layer separately in your DAW, which is a lifesaver for anyone who wants to rearrange or process them later.
The same USB-C port supports four MIDI channels in and out, with nine distinct MIDI modes. So while the hardware itself has no knobs to tweak, you can control the engine with an external MIDI controller. It also accepts MIDI clock in and out, plus analog sync via mini-jacks. There’s a stereo mix output for the post-reverb mix, so you can plug it straight into your mixer or interface.
Basically, it’s a tiny black box with a big button and more connectivity than many full-size synths. And at €125 + VAT, it’s borderline cheap. The shipping cost, however, is another story — $39 to the US via DHL, which is about a quarter the price of the unit. We’d love to see cheaper shipping options, but at least the synth itself is affordable enough to justify the splurge.
Market Context and Who Should Buy
The RND is not a workstation, a groovebox, or a performance synth. It’s an idea generator — a pure source of inspiration for when you’re stuck in a rut. In a world of infinite menus and endless tweaking, the RND is a digital Zen garden: press the button, get a sound, move on. It’s perfect for sound designers who want happy accidents, for producers who need a quick melodic hook, or for anyone who just wants to sit back and let the machine do the thinking.
Competition is sparse — the only comparable product I can think of is the Bastl Kastle, but that’s more of a chaotic drone box. The RND is melodic, multi-layered, and surprisingly musical. It’s also budget-friendly at €125, which puts it in impulse-buy territory. We at Noxal predict it will sell well, especially among the “more gear, less thinking” crowd.
You can pre-order now, shipping in late June 2026, or see it in person at Superbooth 2026 booth Z245 in the tents outside. Just don’t expect to walk away with a saved patch — you’ll have to press the button and let it go.
Frequently Asked Questions
Can I save sounds on the Cyma Forma RND?
No. That’s the whole point. Each press generates a unique sound that is immediately lost when you press the button again. The RND is designed to force you to embrace impermanence — or, as we at Noxal call it, the “studio as meditation” approach.
Does the RND work with external MIDI controllers?
Yes. The USB-C port supports four MIDI channels in and out with nine distinct MIDI modes. You can control the engine parameters and play the sounds using any standard MIDI controller, even though the hardware itself only has one button.
Can I record the individual layers separately?
Yes. The USB-C port transmits all four pre-reverb audio tracks independently, so you can record each layer into your DAW. This is a fantastic feature for anyone who wants to rearrange or process the sounds after the fact — though you’ll lose the original patch once you press the button again.
In a world of infinite knobs and endless menus, sometimes the best tool is a single button and a fresh cup of coffee. Now if you’ll excuse me, I need to press this button one more time before my espresso goes cold.
