We just upgraded from an M1 to an MV. When we quit Vista, the old M1 would send no signal through the DMX out ports, which allowed our wall panel to take over. With the new MV, when we quit Vista the DMX output is held (frozen) to whatever it is right before the Vista application is closed.
Is there any way to change this functionality so that it sends no DMX signal when Vista is not running, like the M1 did?
(Our current workaround is either unplugging the cable from the DMX out port or powering down the computer, but we would like to keep our computer running for other reasons and would prefer to not have to unplug cables.)
