AudioPilz vs. cyma forma RND: The One-Button Synth That Flips the Bird to Tradition

AudioPilz dives headfirst into the wild world of the cyma forma RND, a synth that’s got less respect for convention than a punk at a wine tasting. It’s a one-button wonder (or disaster, depending who you ask) that spits out random patterns and sounds like a slot machine wired to a broken Speak & Spell. In typical Bad Gear style, expect brutal honesty, sharp gags, and a teardown of whether this device is a meme, a miracle, or just musical ragebait. If you like your synths unpredictable and your reviews with extra bite, this is your jam.

Meme or Machine?

The cyma forma RND lands on the desk like a punchline at a synth nerd convention—one bloody button, a daft name, and the sort of concept that makes old-school producers spit out their lukewarm lager. AudioPilz introduces this thing with the kind of savage energy reserved for gear that’s destined to split opinion. From the outset, he’s not pulling punches: it’s described as the unholy offspring of a novelty toy and a half-baked art school thesis, which sounds about right if you’ve ever dreamed of a synth that’s practically trolling its user.

It’s a deliberate swipe at tradition, with AudioPilz poking fun at how the RND seems more like ragebait for purists than a serious instrument. The whole premise is about randomness—no patch memory, no tweaking, just press and hope. The first impression? This is gear for the terminally bored, the brave, or those who think traditional workflow is for cowards.

This godforsaken love child of a novelty toy even Teenage Engineering would be ashamed to put to the market, and a 2005 liberal arts…

Random Chaos: The Sound Engines

The results of Sima Forma's nuclear football for experimental musicians are gone forever as soon as you press the button again.

Under the hood, cyma forma RND is a Frankenstein’s monster of digital synthesis—eight engines, each more unpredictable than the last. AudioPilz lists them off with the confidence of someone bracing for weirdness: Subtractive, FM, Acid, Noise, Speech, Karplus-Strong, Supersaw, and Additive. What you get is a random combo of up to four instruments, four voices each, all spat out as drones, sequences, or jingles, with Euclidean rhythms doing the heavy lifting. The catch? Once you press the button again, whatever you had is gone forever—proper existential synth anxiety.

Editing is almost entirely off the menu, which is a kick in the shins for anyone who likes control. You can nudge things about with MIDI—volume, reverb, transpose—but mostly it’s about embracing whatever Frankenstein patch the machine coughs up. AudioPilz makes it clear: if you want predictability or fine-tuned sound design, this synth will drive you up the wall. For everyone else, it’s pure chaos in a plastic box.

Accidental Genius: Inspiration from the Abyss

Despite all the limitations, there’s a weird sort of magic here. AudioPilz admits that the randomness, while sometimes frustrating, can genuinely spark ideas you’d never arrive at sober or with a more sensible bit of kit. Patches and patterns that seem like a joke at first can end up as the backbone of a track, especially if you’re willing to ride out the wheel of fortune. Sure, sometimes you get utter rubbish, but sometimes you strike gold—and isn’t that what keeps half of us up at night, waiting for inspiration to smack us in the face?

It is surprisingly usable in spite of the gambling like approach and will certainly turn a few heads both in real life and on social media.

Build, Bargains, and Blowing Hot Air

The cyma forma RND doesn’t pretend to be a luxury item. AudioPilz sums up the build as fine for what it is—plastic, yes, but not total tat. There’s an LED that blinks along like a cheap disco, and the price tag won’t make you cry into your pint. It’s a far cry from the wallet-busting price of some so-called boutique gear, landing closer to the cost of a decent night out. Still, the lack of physical MIDI out and the meme-worthy design means it’s likely to split the crowd like a dodgy kebab at closing time.


Press Play, Embrace Chaos

If you really want to know what this synth is about, you’ve got to hear it in action. AudioPilz’s techno jams show off the glorious mess of sounds it throws out—sometimes brilliant, sometimes bonkers. You’ll get a better sense of its unpredictable charm by watching the video than reading any review, because let’s face it: the real experience is in the noise, not the spec sheet. If your idea of fun is letting randomness dictate your next banger, this one’s worth a listen.
