Before I picked up the AX8 (read: last week), I had assumed Scenes allowed you to store parameter differences... e.g. different gain in Scene 2, or more delay, etc.. I wouldn't say I was disappointed, just surprised, that you couldn't alter parameters per scene.
If FAS did add this feature, you could indicate at a glance which parameters had changed against Scene #1 by highlighting their label in a different color (e.g. #FFF white instead of light gray, or a muted blue, etc.).
And like controller Damping, you could define a x-fade time between scene changes so you could fade to a new scene like Kempers new morphing feature (except for block bypassing, which would happen immediately). So essentially the same thing as a scene controller but automatically applied to all modified parameters between the current and target scenes. If you need a block to x-fade too, leave it ON in the target scene, and modify its Mix/Level parameter if it has one.
