What makes you think I want to learn them? I am a musician, physicist, and number freak. I just want to explore, group by common elements, compare with chords, etc. And I have some other applications. It's just a hobby. While I appreciate your always-helpful approach on this and other forums, ignoring my query and suggesting a solution to some other problem is not real helpful. So, do you have any ideas to get a list of scale data in excel to play a midi sequence?
