Make a “Keep Multiple Listen option” on/off on Headphones.
off (default) : Keep Listen buttons on each channel (auto-disengage previous Listen when tapped on another channel)
on: maintain previous tap(s), allowing multiple channels listen thru headphone (manually tap Listen you want to engage/disengage).
I have all out assigned to stage monitor. I monitor thru phones A, I wish I could routing on the fly a group of channels (say, drums, drums and bass) during stage. I miss this analog mixer like feature, keeping Listen button on and simply sum the signal…
