Hope I'm wrong. Nice discussion, though. Anyone else have any ideas? Paul 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) Richard Brekne ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
