BRAND: ADDAC System

MODEL:  ADDAC402 4 Voice Heuristic Rhythm Generator Eurorack Synthesizer Module

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for an ADDAC System ADDAC402 4 Voice Heuristic Rhythm Generator Eurorack Synthesizer Module. The ADDAC System ADDAC402 4 Voice Heuristic Rhythm Generator is a powerful 20HP Eurorack module designed for complex gate and trigger generation. It uses mathematical algorithms and "heuristic" rules to create non-linear, polyrhythmic patterns across four independent voices.

SPECS:

• The module features seven distinct modes that define how patterns are generated: 
  • Euclidean: Evenly distributes a set number of "fills" (active steps) across a defined pattern length.
  • Golomb Rulers: Creates patterns where no two marks have the same distance between them, resulting in inequal, sparse distributions.
  • Probabilistic: Uses the "fill" knob to set the percentage chance that a gate will be output, creating unpredictable variations.
  • Game of Life: Based on Conway's cellular automata; patterns are "born" or "die" based on the state of adjacent steps.
  • Footwork’n: An "inducted error" mode based on a code bug that generates organic, evolving rhythmic events.
  • Pong: A voltage-controlled version of the classic arcade game where gates are triggered when the "ball" hits the walls or paddles.
  • Gate Sequencer: A standard 32-step sequencer for more traditional, manual pattern building
• Voices: 4 independent voices, each with a dedicated gate output and a complementary inverted (logic NOT) output.
• Physical Size: 20 HP width and 5.5 cm depth.
• Memory: Includes 16 storable preset slots to save and recall complex configurations.
• Controls: Features a clear OLED screen, global swing control, play/pause trigger inputs, and dedicated "Step" and "Fill" knobs for each channel.
• Power Consumption: Max current draw is approximately 150mA.

• Eurorack Power Cable
