Extremum is an effects processor built with one huge goal: to turn even the most simple sounds into insanely interesting, tonally rich and exciting new material. It features a collection of phaser, chorus and filter algorithms comprised of up to 256 stages, producing extreme, radical but still finely controllable transformations. And to take it even further, Extremum has its own tempo-synchronised modulator with multiple waveforms, variable lag and chaos.

It would not be a Sinevibes product if Extremum did not feature a stylish, subtly animated user interface. With its clean layout and colour-coded controls, you will hardly ever need to glance into the user manual. The graphics also do not tax your Mac's main processor and support displays with retina resolution.


  • Six extreme effect algorithms: 256-stage phaser with 16 feedback lines, 8-voice three-stage chorus, 16-stage positive/negative comb filter, 8-stage positive/negative barber-pole phaser.
  • Modulation generator with 8 waveforms, adjustable lag and periodic chaos.
  • Advanced transport sync algorithm with support for tempo and time signature automation.
