@Patanjali… all that is way too up in the clouds for =me=. All I can tell you is that the -performance- part of the equation is mostly possible NOW. Samplemodeling gets =much= closer, using just Kontakt scripting. VSL can create ‘auto-switching’ patches that are pretty good. Not perfect, but pretty good.
The problem is that, all that controller data doesn’t get translated to notation properly. And/or there’s no support for ‘expression’.
It’s -possible-, it’s just that sample lib makers don’t choose to support Note Expression and notation programs don’t translate the symbols into universally understood MIDI/controller stuff… again Note Expression could probably handle this. The reason they don’t support it? Lack of demand by… as you say… people who can’t see beyond the status quo.
