Possibly. It’s difficult to measure the degree of difficulty between such things.
But my point was that orchestral music has this GREAT advantage; this point-of-departure in the score sheets, through which they can interpret more or less freely. Electronic music doesn’t have that.
I know that both you and I champion the great freedom in having an orchestra do their own thing, and not let the original film performance be the be-all, end-all benchmark of how it should sound.
