Just focusing on the ProChannel, and forgetting the console view and track view (and being mouse wheel works in those views, so provides something more usable), I can' understand how those making ProChannel Modules can make it work in Default sizing, but Cake can't. Surely they are making them to Cakes protocol?

Again, I really don't know the intricacies of coding. But maybe Cakewalk can benefit from how others handle their ProChannel modules.

Ok so in this thread http://forum.cakewalk.com/Controlling-Knobs-and-Faders-with-QWERTY-Keyboard-m3188536.aspx I found out what those four white corners represent,

that is the control is 'in focus'. When a control is 'in focus', you can use the plus and minus keys to move (except for the QUAD EQ flyout which doesn't respond for some reason, along with the PC QUAD shelving slope with just the minus button working). The + and - are consistent no matter the display sizing.
 
This means on the default setting, the PC Tube and Compressor have a workaround (the Quad EQ too (except that shelving slope) but that had the right click/left click workaround that Tube and Comp didn't)
 
I've now pinned the control panel's Display option to my task bar, so I can jump between scaling. This is useful as the Applied Acoustics Systems Plug-in are tiny on Cakewalks 'smaller' recommendation, but much more usable on a 150% setting.
 
I now know why Cakewalk say the smaller in Windows 8 is the 100% setting, despite not being Windows recommended. On this screen

 
If you tick 'let me choose one scaling level for all my displays', the screen states smaller is 100%.
 
The main screen that is usable for touch screen is the Console view. If I was to get a second screen I'd hang it above my Laptop, with that showing other views, and the laptop being reachable, the Console View. But at the 'smaller' setting, it makes the touchscreen really tricky.
