How do I bind multiple mixes together? So if I drag down the slider for a channel on one mix, it will drag it down for the others at the same time for simultaneous output adjustment?
MCAs aren’t supported, but you can have any mix follow your main mix by setting that mix to POST fader.
To expand on Scott’s post double patch the channel you want to simultaneously control all the mix sends on, the second channel will be used to control the mix sends all set to post fade, on the second channel be sure to un-assign it from the main mix output.
You can use the head amp gain.
