Hi Steve, Thank you for the information. It does not give the results, I was expecting. I was thinking, that the same RH, would result in the same FAC, but then the piano would have to be at the same pitch, also. It is obviously, more involved than I was thinking. I didn't even remember, seeing that article, although I must have read it. It is going to be good having, the old issues, on CD-ROM, and being able to search. I hope it is available at the National, this July. Regards, John M. Ross Windsor, Nova Scotia, Canada.
