With the strings at the same measurable pitch at the measured partial, they should be in tune, right? But they aren't necessarily, to your ear because a string doesn't vibrate in a clean simple wave at it's fundamental pitch. The differences you are hearing that the ETD isn't allowing for are all over the place instead of at one very narrowly specific pitch. That's the fuzzy analog "least bad" wetware algorithm at work, and even if it was available in an ETD, folks would still be lining up to argue with it. It's what we do. Ron N
