1) Very likely - I think sometimes the input and output parameters were reset when updating.
2) the volume in amp section and cab section were ONE parameter displayed in TWO places - ie. when changing the cab volume, the change was also seen in the amp volume. They removed one of them (ie. the display of the parameter). Only a UI change, not a change of sound or number of parameters available.
Ah.
Well, you can't have cabs by themselves, they're always a part of a rig. Meaning, you can't load "just a cab" in the kemper, they're always loaded as part of a rig with an amp section. So the parameter is stored with that rig, and thus not lost.
Then what is actually happening when I load a rig and then save off just the cab? It shows up as a standalone cab at that point which I can load into any rig. And if I'm not mistaken that cab maintains it's own set of parameter independent of the rig from which it originated. Or am I completely overlooking something??
I don't know exactly what goes on behind the scenes. I would think that - also in the earlier OS 3.3 - the cab is separated from the parameters of the rig (eg. the cab volume). That's just an assumption on my part, but I'd think that's how it works.

Right, that's my assumption as well, and how it appeared IIRC. Meaning the cab volume became specific to that instance of cab that was saved off separate from the rig. So when the OS upgrade subsequently occurred the cab no longer had a volume parameter. Which is understandable. But I had specifically set the volume of one cab up a few notches. Which is the basis for my question of what then happened to that setting? Is it tossed away entirely as no longer having any meaning relative to the cab, or is the intrinsic baseline cab volume now adjusted relative to the last volume setting prior to the OS upgrade?
Not sure I explained that very well.

Hmm... I don't know, to be honest. Did the cab volume parameter "carry over" to the rig you applied the cab to earlier?

That a saved cab maintains its own set of parameters is correct. But volume is not one of them as @Michael_dk has pointed out because previously it reflected the amp volume in another place.
Also bear in mind that with Studio Profiles the saved cab will always contain a portion of the amp it was profiled with.

Ingolf brings up a very good point - if the cab was indeed saved INCLUDING any tweak to the volume parameter, how would the kemper apply that cab to another profile which had already had its AMP volume tweaked? I think there's no change to this functionality in the later firmwares.
Ah, so you can hear a difference. Maybe that boost is now baked into the cab portion as it was saved separately.
I guess you could just find the cab in the original profile and save that separately again - problem solved?
In that case, I suspect that maybe that cab just has a higher volume. Sometimes it seems that some rigs are louder than others even though they shouldn't be. Might be a frequency thing. Maybe check that the volume in hte AMP section of that original rig wasn't set higher than zero?
Interesting topic. I suggest contacting support.
I never stored cabs with volume changes separately so this question didn't come to my mind when the update came.
Perhaps there's something written in the release notes.
