Important Note: This is a brand new feature and I am still tweaking it. If you get sporadic readings, it’s likely because the 3 strings that make up Middle C are so out of tune with each other that a clear reading is not possible. If this happens, it’s a clear sign that your piano is very out of tune and needs a pitch adjustment (New Customer Service).
