Just to expand slightly on what Steffen said, this is a workaround to create pop-group-like keys:
– set up different layouts of the surface with the strips you want in each
– save each one as a Scene
– use the Recall Filter for each Scene to block everything, with the exception of the Strip Assigns
– these Scenes will now recall different surface layouts and nothing else
– assign a bunch of SoftKeys to recall these Scenes
– check SoftKeys are safe in the global Scene Safes, so their assignments doesn’t vary with every Scene you recall
An alternative to the Scene Recall on SoftKey is the combo function Sel Mix PAFL Scene. Monitor engineers love this because with a single button press you can:
– Select an Aux master (for example to tweak the wedge GEQ)
– Select the same Aux as the active Mix (sends on faders)
– Activate PAFL on the same Aux
– Recall a specific Scene with a strip layout dedicated to that Aux (typically just the channel contributing to the monitor send)
