Hello Don Rose. Reply to two postings: Yes, That is the unit I mean. It has the facility to show pitch changes to within 0.1 cents. Who needs any closer? and: I find we are at variance in our understanding of C0 and C1. This was purely my own nomenclature for my own use. I simply call the bottom note x0 and all in that 8ve. x+0 then, at the first repeat go to x1, x#1... ad inf. That way there's no possible confusion. But then as I said, I created this for my own personal use.. Regards Michael G (UK)
