The Jesusonic is a fully programmable effects processor for guitar, bass, vocal and general use. Effects can interact with eachother (for example, a volume detection effect can trigger a tremolo effect), or (especially in the case of the Jesusonic CrusFX 1000) with the user (you can assign triggers to effects like loop samplers, for example). A wide assortment of built-in effects are included and users can modify effects or write completely new effects on the fly.

Supports CoreAudio for i/o (though input and output is limited to the same device).
