Almost all progress is incremental. Look at it from one angle, and it looks like "spinning our wheels". Look at it from another angle and it looks like almost all progress in almost all fields of human endeavor.

Neither of those papers cover any of the technology or ideas behind what Melodyne introduced with polyphonic note editing, which allowed the editing (in time and/or pitch space) of a single note within the audio of a polyphonic performance.

I'm entirely fine with saying "getting computers to do things humans have done for a long time isn't really progress". I'm not sure it's true.
