The SWITCHMATRIX 4x4 has four inputs and four outputs; via dedicated, iluminated buttons you can make freely every connection between these, no matter if CV or audio signals. Each routing / connection setting can be stored in one of 64 preset memories. Selecting the presets is possible by up/down triggers, CV, and of course by two up/down buttons.
A performance mode makes it possible to switch between 16 presets by simply pressing one of the matrix buttons - quite handy for live use!
