As far as I can see, Mute groups on SQ are hard, i.e., the only way to unmute a channel that’s muted as part of a mute group is to deactivate the mute group. This is often inconvenient, and it would be great to be able to use the channel mute key to override the mute status of that channel.
The main use case for this is where I have a mute group across a whole band stage, but then an anouncement is needed from the main vocal mic. The only way to unmute that mic is to deactivate the mute group – which obviously unmutes everything – hardly ideal.
