Use Quick Channels
Quick Channels are instrument or source-centric whole channel presets which
allow the user to mix quickly by adjusting multiple parameters with just a few
controls. They are useful for non-technical users who don’t want to get lost in
menus and parameter values, but also for more technical users who need to work
fast but may want to make more in-depth adjustments later.
