I don't think the program is actually *designed* to resist
falsification, but is, rather, limited in the range of music that it
can effectively retune by virtue of its goals: to retune music
conceived as sectionally diatonic to as close to small number ratios
as possible, and to distribute the commas in such a way as to fool the
ear into thinking there were no comma shifts. I actually preferred the
older version where the comma shifts were in your face, and the
intervals rang (in the Barbershop sense) more.
