Befaco Promised €666 for Its Eurorack Groovebox. It's Shipping for 37 Euros Less.

What exactly do you get for the money?

Befaco and Tesseract Modular built ARK as a 40HP Eurorack format split across two units: an 18HP Core that houses the sequencer engine and the synthesis voices, and a 22HP Controller carrying the display, encoders, and most of the physical I/O. Together they run a 16-track sequencer with patterns up to 64 steps, switchable between deterministic, stochastic, and Euclidean logic per track, with 16 internal modulation sources keeping patterns moving without extra modules.

The synthesis side generates drum, bass, and melodic voices internally, plus sample playback from onboard RAM or a microSD card, so ARK works as a standalone instrument, not just a box you patch into a bigger rack. Per Gearnews, Befaco frames it plainly: "ARK is both: a versatile MIDI and CV sequencer and a self-contained instrument."

I/O is generous for a two-module box: 8 CV/gate output pairs, 6 CV inputs, MIDI In/Out on TRS mini jacks, clock and reset I/O, and a USB-A host port, all triggered from 16 Cherry mechanical buttons and four knobs.

Why did the price drop below the announced target?

When Synth Anatomy first detailed ARK in May 2026, Befaco's quoted price was €666 including VAT, pitched for a late-2026 ship date. ARK is now actually shipping, at $593 / £537 / €629, under that original figure. That runs against modular's usual pattern, where an ambitious boutique project tends to creep up in price between announcement and delivery, not down.

Does it work as a standalone instrument, or is this another sequencer you'll outgrow?

The spec sheet suggests Befaco built ARK to stay useful at every stage of a rack. Copy, paste, clear, and undo sit on dedicated hardware buttons rather than buried in a menu, carried over unchanged from the May prototype. Patterns can drive ARK's own voices, or leave the rack entirely over MIDI and the 8 CV/gate pairs, so it still works as a pure sequencer brain for a bigger system once you've outgrown its internal synths.
