Befaco ARK
16-track Eurorack groovebox: sequencer, synth/sampler engines, CV, MIDI and mixer in one.
40 HP Eurorack module
Befaco ARK, developed with Tesseract Modular, is a 40 HP Eurorack groovebox that folds a 16-track sequencer, a bank of synth and sample sound engines, harmony/scale tools, an internal modulation engine, and a mixer with FX and master dynamics into one detachable, two-part module. Each track runs a deterministic, stochastic or Euclidean sequence into its own engine or CV/gate generator, and its output can be sent independently to the eight CV/audio outputs, eight gate outputs, or MIDI. The left half gives hands-on step editing (Note, Velocity, Length, Chance plus per-step tools), while the right half's screen, four encoders and menu buttons handle device editing, modulation and mixing.
Features
- 16-track sequencer with deterministic, stochastic and Euclidean modes
- Per-track sound engines: synth voices, samplers, or CV/gate generators
- Percussive engines (bass drum, kick, snare, FM perc)
- Bass/lead engines (acid, lead, bells, rubber, modal) and polysynths for chords
- Sample playback with slicing from internal RAM or microSD card
- Harmony tools based on chord progressions and scales
- Internal modulation engine with up to 16 sources
- Internal mixer with FX and master dynamics
- 8 dual CV/audio outputs and 8 gate outputs with flexible routing
- 6 assignable CV inputs (A-F)
- Full MIDI sequencer: generation, recording and parameter control (TRS MIDI in/out)
- Clock and reset in/out for system sync

- Step 1— Backlit Cherry-MX pad 1 in the 4x4 performance grid. In Step mode it toggles step 1 of the current pattern on/off (its LED shows step state
- Step 2— Backlit Cherry-MX pad 2 in the 4x4 performance grid. In Step mode it toggles step 2 of the current pattern on/off (its LED shows step state
- Step 3— Backlit Cherry-MX pad 3 in the 4x4 performance grid. In Step mode it toggles step 3 of the current pattern on/off (its LED shows step state
- Step 4— Backlit Cherry-MX pad 4 in the 4x4 performance grid. In Step mode it toggles step 4 of the current pattern on/off (its LED shows step state
How-To Guides
- Program a kick-drum track
- Add generative variation
- Send a bass voice out as audio + gate
- Slave ARK to an external clock
- Play engines from MIDI and record
- Modulate a parameter with an internal LFO
