I setup a soft key to a mute group that mutes all FX send/receive.
I have 4 mute groups: all I/O, just fx send/receive, all input but st2/3, all input but lead vocal mics. I then assign soft keys: MG 1, MG 2, MG 3 and cancel all PAFL.
Before firmware update this was done in the USB Audio page but that page has been moved/removed with the 1.1 update. Now you have to select a channel, select processing, select preamp, press the Fn button for source select. Now you get the Source Select page.
There must be a better way to easily select Qu-Drive USB from the Qu-Drive pages.
