An advanced 4 track sequencer for eurorack!

Sequence 4 voices with CV, Gate, and Modulation! Complex per-step configurable parameters provide capabilities to effortlessly create intricate sequenced arppegios as well as tempo synced modulation outputs that can change instantly on any step - steps can contain Rhythm or Pitch probabilities or be modulated externally in many different ways, providing an exteremely power yet still intuitive sequencer!


Fluxus One presents each user with a diverse set of features. Designed to be immediately intuitive, the pathway of learning allows a user to grow into the module.
