To whom... As nice as the Bezier spreadsheet is, someone asked me if something similar could be done using more than four data points. So here's an Excel spreadsheet for graphing hammer weights with a spline curve. I have it set up here for 8 data points, using all the "A"s and C-8, but everything is there for you to set up any number of sample points at any points you like by changing the cell ranges in the formulas in the appropriate column. http://tinyurl.com/6928t https://www.moypiano.com/ptg/files/attachments/38/46/39/7d/spline.xls Ron N
