In a simplistic way, The Mod Medusa could be described as a Euclidean LFO : an “algorithmic” modulation source which produces variable period LFO signals synced to rhythmic patterns. Those patterns are generated by algorithms such as the  classic Euclidean one or from different algorithms adapted from the Shakmat White and Knight’s Gallop. The Mod Medusa has 4 outputs which generate 4 correlated LFOs, giving different “polyrhythms” according to the chosen mode.

Generated waveforms can easily be twisted using the symmetry and shape parameters which continuously morph the signal into different waveshapes. The range of  panel controls and assignable Gate and VCA Inputs turn the Mod Medusa into a strong performance tool. A very unique but cohesive approach to modulation which leads to instantaneous and original results!
