The EC-Mute is a 2HP expander to the VPME Euclidean Circles. It is running on the same Firmware as Schleußig so it basically offers the same performance friendly way of switching channels of the Euclidean Circles on or off.
Grouped switching: press GROUP and select multiple channels to go either on or off as soon as GROUP is released.
Synced switching: when SYNC is activated and a global clock is present switching of said groups starts at the beginning of a bar (quarter note, half note, two bars, 4 bars – user selectable). Perfect drops after breaks etc.
