The final MaxforLive device of the Modular Series XL pack is an Audio FX device, Isotonik FX was born out of frustration with Beat Repeat. It works on buffered audio and slices the incoming audio into 1/8ths which can then be retrogressed via MIDI whilst the original audio continues playing, much like the Slip mode on CDJ’s. You can set how long the repeat cycle is for the slices to bring some glitchy stuttering that always remains on beat and on time.
