Forgot to add, the notation product does do the slurs and hairpins, but, of the worst, lack of slurs in a midi export pretty much botches playback in terms of any quality, huge issue. I wouldn't argue the point with anybody, but AI could clearly resolve issues to the ear's general satisfaction, though don't ever expect to see this effort made with a notation tool set, since I really don't believe there's the demand for this, when there's precious little evidence on the web enough people are manually scoring.
