Yeah I guess they fulfill some rolls but not others, hence things like the S5 and S6 and many other surfaces out there. For me it is kind of like the pan law, different consoles had different pan laws and didn’t really give values on panner you just got an idea of what the relative change was with the panner and went with it.
Pro Tools pan law was fixed (and other DAW’s) until version 9. Cubase and Nuendo always let you tweak which was cool and part of what draws people to their software no doubt. So when we can’t tweak it is frustrating.
If you ever figure out a way to do this please post back because I would love to know! I wish I could have been of more help.
