For some installations where more most of the users are just using the Q control APP with no access to the mixer (in these cases it’s a QU Pac) and the system power is a remotely controlled sequencer it would be handy to have the option to assign “shutdown” to a softkey.
For safety you would need to hold the button for maybe five seconds to prevent accidental shutdowns.
The softkey could be assigned to Q Control for proper shutdown remotely.
