I finally clued in. ISA and ISO are different Acronyms but upon further research they end up being the same.
ISA= International Standards Association.
ISO= International Standardization Organization (ISO is the table acronym).
I think they are trying to shift away from the ISA acronym because it has so many other meanings.

Anyway here are some rough draft ideas for the popup.

Quote:
Options box:
C4 (default checked) "International Standards Association (ISO)" option. "Advantages link".
C3
C5

Educational links Below. Do not show this popup again==>" ".


The advantages link could say "To the best of our knowledge all chromatic tuners follow the ISO standard. Choosing C4 causes the (Vocal Wizard the notation window staff lines) to match these tuners.". You might want to list as many tuners as you can find as I did that show the note in scientific notation and show the frequency. This will be helpful for some wanting to buy a tuner.

The educational links could be in the form of questions. They click on it to get the answer.


I found one tuner in 9 tuners that does not follow the "International Standardization Organization (ISO)" standard. The BIAB tuner. I have updated the 1st post.
