Well, first and foremost thank you for your compliments! It’s always nice to be appreciated by other musicians, and your comments are most welcomed 
As I alluded to in a few posts above, I am not by any means comparing the flexibility factor between the two systems…or overall performance level. Clearly GP has taken considerable strides over its competitors, and I am looking at my conversion with more enthusiasm each day! Of course, there are some features I will likely NEVER use. I am sure that most users out there don’t use EVERY feature. But, I am looking forward to taking advantage of some things that were either impossible to do with Forte, or were extremely cumbersome (like muting all CCs coming into a synth, yet remapping the hardware knobs afterwards through widgets…that will be awesome).
For the examples you describe above (in Forte), for the electric piano / string scenario (which I do currently do) I would simply disable the elec. piano expression pedal and enable it on the strings to bring them in when I needed them. Forte will allow up to 4 Key Ranges per route…so that is easy to get the octave I would need. Losing the expression pedal might be a concession for some, but not for our band…we premix everything so there is a constant from venue to venue, but that scenario is a whole other topic!
Your 2nd example (the synth solo one) is intriguing and would likely be advantageous to some…but I don’t see it for this music. And, no…no way in Hell Forte could do that!
I am enjoying myself thus far. I have a long (and I mean…a loooonnnnggg) way to go in rebuilding almost 4 hours of Yes music patches. But, baby steps. I look forward to the new opportunities.
Best,
Joe
