[pianotech] SAT IV extended

[David Ilvedson]

But how do you access the page of memory quickly?   I'm assuming you go through the pages until you find the serial # or description?   I think we all can come up with different FAC numbers.   I remember you mentioning disregarding F numbers over 10.5.   What I don't understand is what happens to the intervals if you, for instance, use a lower F #?   I think the SAT IV can show you on your computer the spread of numbers...?   No matter what, of course, we are aurally listening to what the tuning sounds like.
