Yeah, if the original score is digitally encoded such that everything really is a first-class citizen (and not, say, a GIF of some scribbles) -- a very big if -- but if so, it's not obvious that any information has to be lost in translation to Clarinote, nor that Clairnote would impose any additional information. If you want to know the scale you could encode the key signature, which Clairnote seems to make possible, just unnecessary.
