One thing we can all do is mail the three biggies Reyburn, Sanderson, and Tom and
ask them to include more features in these products use as measuring devices.
String partials should be able tobe measured in  cents (in both the Sat III manner
and in the manner Reyburn uses) and hz, (for some purposes hz are handy) and the
data should be able to be exported in ascii format for use in spreadsheets / math
graphics programs. Tune Lab is the only one of the three so far to have this
option and its only in cents. (which admitedly has more uses then hz for our
purposes, still the extra option of having hz would be nice)
