I first encountered the Levenshtein distance at work (where I am part of a team developing SIL-4 level operating systems for use in the transportation industry), as part of our coding rules which describe the differences in variable names allowed (e.g. "char fic; char foc; // ") .. After I looked up the algorithm on my own intuition, I realized it had applicability to MIDI sequences in unique ways, and thats how it came about.
