A Hobbyist Just Gave the Elektron Model:Cycles the Synth Engines It Was Never Sold With

Elektron builds some of the most locked-down grooveboxes on the market: fixed engines, fixed I/O, one firmware per box, buy the model that has what you need. A developer going by 18nelli18 just ignored that premise entirely.

Their release, Modded Cycles, is free, open-source custom firmware for the Model:Cycles FM groovebox, and it does something Elektron itself has never offered on that hardware: it flashes the operating system from the pricier Model:Samples into the Model:Cycles, so a single unit boots both firmwares. Stock Model:Cycles owners get FM drum synthesis. Modded Cycles owners get FM synthesis and sample playback in one box.

What does the mod actually unlock?

The headline fix is audio I/O. The stock Model:Cycles only streams a stereo mix over USB, a real limitation for anyone recording into a DAW. Modded Cycles adds per-track USB output across all 6 tracks at 48kHz/32-bit resolution, so each track can be routed and recorded separately, the stereo mix no longer transmits over USB, but OS updates via USB keep working.

Then there's the synth-engine unlock: the custom firmware reads an owner's Syntakt OS file and loads two of its digital engines straight into the Model:Cycles, SY BITS (chiptune-style synthesis) and SY SWARM (supersaw-style synthesis). Neither engine shipped natively on this hardware; Syntakt costs roughly three times as much. The project also ships a stack of experimental, alpha-stage extras on GitHub: a seventh sampler machine with seven playback modes, resampling, a beat-repeat page with master effects, filter and resonance on the stock machines, and scale lock.

"The flasher puts the official Model:Samples OS inside your Model:Cycles firmware file. So you have both firmwares in one hardware."

Is this an isolated project?

No, it's part of a wider pattern. Days earlier, a modder going by Soejrd released Digisophie, unofficial firmware for the original Digitakt MK1 that adds an entirely new metallic percussion synth engine with 8 programmable parameters, again capability Elektron never shipped on that box. Both mods arrived within the same week, both are free and open-source, both target hardware whose official firmware Elektron keeps tightly scoped by model tier.

It's the same logic that produced dysentery and beat-link for Pioneer's Pro DJ Link protocol: hobbyist developers reverse-engineer a manufacturer's closed system and hand the unlocked version back to the community for free, no vendor involvement, no endorsement, source code public for anyone to audit or extend.

Why it matters

Neither mod is endorsed, signed off, or supported by Elektron, and flashing third-party firmware onto a $500-plus groovebox is squarely DIY-at-your-own-risk territory. But it puts real pressure on the model-tier business: if a free community flash can add FM-and-sample dual-mode plus two borrowed synth engines to the cheapest box in the range, Elektron's pricing ladder gets harder to justify to its own customers.
