No, soloing is not what I want to do. Say I’m doing virtual or realtime soundcheck and want to listen to one or a few channels at a time through the PA. The current configuration disallows me from using mute groups because the mute group overrides the channel mute, and I have to hard-mute all channels before opening the mute group, and remember to un-hard-mute them before show. It’s not like there are many options for mute group control on the SQ-5 either, with limited soft keys.
