Spill expand…
Both are techniques to show tracks that are controlled by a VCA.
Yes they are slightly different.
On the S6 you can spill left/right from the VCA master. With the Nuage you hit expand and everything connected to that VCA will show on the surface.
It’s not the same but they IMO serve the same purpose and do the same job.
Important side note is that expand does not fully work over eucon and that is a big drawback. I can’t understand why Steinberg has not been able to implement this for eucon.
