Quick demo of the MMM/Division 6, SQ816 sequencer. 
Highlighting the running mute. The running mute function kills the main gate when the button (or footswitch) is pressed.
The setup is two CV busses running two independent voice chains.
The B bus is fired from either the main gate or, from taps in the 2,3,5,and 7 stage gate outputs.
When the running mute is pressed, only the B voice chain comes through until the foot swith is released. Then, the main gate kicks in and all stages on both voice chains are triggered.

NOT a pro production. Just a quick recording while testing the system.
