BIGZUN EUKLID Eurorack Euclidean Rhythm Generator 4HP Dual Trigger OLED Module

BIGZUN EUKLID – Dual Euclidean Rhythm Generator, 4HP Eurorack Module (assembled and tested)

EUKLID is a dual Euclidean rhythm generator in just 4HP. Feed it a clock, choose how many hits should fall on how many steps, and the module spreads them as evenly as possible – just like many traditional rhythms of the world. Two channels of different lengths drift apart and meet again, so two simple settings grow into long, evolving polyrhythms.

What it does

• 2 independent channels, A and B: STEPS 1–32, HITS 0–STEPS, ROTATE, pulse length (10 ms trigger or 50 % gate)
• SPN auto-rotation: the pattern shifts by itself every 1–8 cycles
• CLOCK and RESET inputs, OUT A and OUT B gate outputs
• Animated 0.91" OLED screen – both patterns as rings or columns, current step and the edited value in large digits
• 3 buttons: −, +, MENU (hold MENU to enter and leave the menu)
• Settings are saved automatically
• Factory setting: A = 5 of 16 (bossa nova), B = 7 of 13 – together they line up only every 208 clock pulses
• Great for kicks, hi-hats and envelope gates, polyrhythmic sequencer clocking and slowly evolving Berlin School patterns
