On the QU-16, is it possible to monitor different mixes from the same output, and be able to switch between them without changing the physical output? For example: I am the bass player and sound man in my band, and we use in-ear monitors. I need to be able to monitor my mix (5/6 out) and also be able to switch to main LR mix at times to hear the mix in main FOH speakers. It would be nice to set up a soft key to switch between the 2 mixes. For that matter, it would also be nice to switch between the drummer, and guitar player mixes (7/8 and 9/10) to be able to check what they are hearing in their mixes. Thanks in advance for any advice.
