Littau-Conrad Spreadsheet Demo 2
This video shows how a tuning is created using the mapping notes taken from the piano to be tuned.
The first step in the process is to tune A4 to A440. Once A4 is tuned, it’s 4th, 8th, and 2nd partials are measured.
Then A3 is tuned as a pure 4:2 octave. Then that 4:2 octave is measured as a 2:1. That 2:1 width is called the ‘4th A4 number’.
This video touches on that first step and shows what one of the pages from my mapping notes look like and how they are arranged on the page.
Also in this video is a little discussion as to how those initial A4 numbers, combined with the 4th A4 Number, help to begin the mapping process.
Using the page from my notebook, I show how some of the settings of the A4 numbers and the 4th A4 Number, and the new found location for A3, can be used to help find good starting points for notes not yet mapped. Some of the relationships between the 2:1 and 4:1 octaves can easily be seen when looking at the Mapping Notes.
This video shows how the mapping information contained in the mapping notes is entered into the Templates Tab of the Littau-Conrad Spreadsheet. It also shows how the Filter boxes work and how templates can be selected for the different sections of the piano (A0 – A1, A2- A4, A5 – A6, and A7).
This demo also introduces the Littau-Conrad Spreadsheet’s ability to tweak the midpoints of the tunings 3rd and 4th octaves during the Adjust Tab’s tuning creation. This video also shows the differences created by a Template type tuning creation and a Polynomial tuning creation. It shows that there are good reasons for both types for different piano mapping information.
The video below then shows how the Edit Rounding (round off errors) can be smoothed out, and again how the tuning is then moved to the Export to Piano Manager Tab where it is then named, saved, and exported into the Inventronics Piano Manager software so it can be sent to the SAT for the tuning of the piano.
Again, this is just a demo of the LC Spreadsheet trying to give an idea as to the ‘flow’ of the procedure going from the mapping of the piano with a SAT to a finished custom tuning in the SAT.
