hey soens, 
 
i agree to a large extent with what you are saying, but you need to remember that rapture and dimension are *quite* old.  I found the gain staging inside the synths very helpful when using multiple samples, because there IS a bit of attenuation going on per element.  That means for me, as an end-user, it is actually less trouble layering multiple samples without hitting red.  Oddly, more times than not, if you copy the same one shot into EVERY element in dimension and play back at velocity=127 then you get 0db (or quite close).  This was to me very good thinking on Rene's part because it's easy not to clip.  
On the other hand, you can take the same sample and drag it into Kontakt then remove the ADSR envelope and push the velocity modulation intensity to 100% and when you play the root note against the original sample with inverted phase it will null.  
I don't think either way is a limitation by any means, just a different way of working.  But this is why we have hammers and screwdrivers.
 
Best, 

@Soens - I also meant nothing combative or anything like that, in my earlier post, in fact I hadn't even thought about the issue and thought it cool that someone had contemplated it.
 
I was just trying to make the point that since the beginning of time, synths have had volumes all over the place, not only between different synths, but also between different presets for the SAME synth.
 
Having grown up with that being the case, I learned to just accept that this was the way of the world, so I just tweak each and every preset without even thinking about it.
 
There isn't even a standard on what actual note C0 maps to, let alone volumes, so I just muddle my way through it and try not to paly too many wrong notes (jazz).  :)
