Auxilarry ....
From the 2nd video, isnt that a role keyboard olayers often have in bands, even if they are the only keyboardists?
A basist, a drummer, and 2 guitarists domt leave much room for keyboads.. espescially the gutarists seem to have the habbit of trying to fill the whole soundspectrum...
most bands today use 2 or 3 keyboard players each playing different parts this is where the synth workstation shines....
