You were the one stating “Ok but how exactly would that giant thing (…)” implying that a Prime 4 with bigger 7" jogs would turn into a “giant thing”, hence I demonstrated that it can remain exactly the same size as the current Prime 4 by making better use of the surface are, like other gear (with even bigger jogs) manages to do as well. This has nothing to do with “Apples vs Oranges”. I have clearly marked the affected areas, none of those include any AiO-specific controls, just the mixers and effects.
One of the reasons I really like the SC Live 4 is the mixer layout. Most reviewers praise it for the “club standard” layout, but I add to that the much more compact arrangement of controls, like on the DDJ-1000. In other words, the gaps between the EQs, faders, etc. on the P4 are unnecessarily big. I guess because they wanted to align it perfectly with the screen. However, this plus the two EFX banks, really limited the remaining area for the decks, and with that, the (rather) small jogs.
In short words: Bigger jogs are perfectly possible without affecting the overall unit’s size.
(If you didn’t imply that with your post above, have my sorry and just ignore my explenation)
