As I remember, when setting the initial ladder of a 3ds/6ths  
temperament, the C#3-F3 M3d had the same beat rate as the C#4-F4 3d.  
Actually achieving the flat slope of M3ds beat rates which the  
Baldwin 243 vertical only dreamed of. I also remember tuning the  
acoustically (no external speaker).
