Library Files or .LIB files are the type of files used by the Sanderson AccuTuner IV’s ‘Extended’ Memory. This upper memory or ‘Extended’ memory greatly expands the capacity – the number of tunings – that can be stored in the SAT IV. This video will show how to use and work with Library files and Piano Manager for storing and retrieving tunings in the Extended memory of the SAT IV. (Post contains Video)
This video shows how a tuning is created using actual mapping notes and how the targets are arranged on the notepad. There is also some discussion in this video on how the “A4 numbers”, combined with the “4th” A4 Number, help to begin the mapping process. Using the mapping notes combined with the A4 numbers,…
The video below is a preview of the Littau-Conrad Spreadsheet presenting how our LC Spreadsheet looks and works with Piano Manager and the SAT IV. Creating the tuning begins on the Templates Tab. Once the targets have been entered into the ‘Targets’ boxes on the Templates tab, clicking on the ‘Copy to Adjust Tab’ begins…
Even the smoothest set of software-created numbers for the prime octave’s tuning ‘curve’, will often not be a good fit for the piano.
Because we can’t use the same partials to tune A0 and C8, there must be at least one partial change in every tuning software system. All tuning software systems contain partial ‘changes’. Whenever the software switches from one partial to another during the course of the tuning, an error at that partial change is very likely. Since every partial change is a potential tuning issue, the fewer partial changes the better. The higher partials are less reliable then the lower partials.
