The ‘main’ targets are every A on the piano (including A0 and A7).
The ‘mini’ targets are the D’s and E’s in the 3rd and 4th octaves.
The LC spreadsheet uses the locations of target notes to create the tuning.… Continue reading
The '4th A4 Number' is the width of the prime's 2:1 after it has been tuned as a pure 4:2. Knowing this 4th A4 number from the very beginning lets me know immediately what I'm going to be dealing with on that particular piano. Continue reading
Once A4 has been tuned, the locations of it's 2nd, 4th, and 8th partials are measured. Continue reading
Mapping the treble uses:
1. information found when the A4 numbers were measured and
2. the completed mapping of the prime octave: A3, D4, E4, & A4. Continue reading
Once the location for A2 is known, mapping A1 is very straightforward. A good location for A1 is as a 6:3 octave (from A1), 3.0 cents wide. Continue reading
Mapping A0 can be done any number of ways. It can be mapped however you like, but just like A1, once you have it where you want it, it's location must be measured using it's 4th partial, since the LC Spreadsheet uses the 4th partials for A0 - A4. Continue reading
Template: A gauge, pattern, or mold (such as a thin plate or board) used as a guide to the form of a piece being made; an overlay; something that establishes or serves as a pattern. Continue reading
When we were working on all this, we kept needing to talk about the A3/A4 octave. Over time, it just became easier to use the words 'Prime octave' instead of saying the A3/A4 octave. Continue reading
Mapping (and tuning) notes during the mapping process is the equivalent of setting the temperament in aural-only tuning. Continue reading
Inaccurate partial changes in tuning software can create problems in the tuning. When using any ETD's computerized tuning system software, errors at it's partial changes are common, can be large, and can easily cause audible 'hiccups' in the tuning. Continue reading
When using any tuning software, different partials are used to tune different parts of the piano. The partials used are designed into the software. All tuning software systems therefore contain partial ‘changes’ as part of the tuning.… Continue reading

Available for download here is a group of individual pianos (complete 88 note tunings). These tunings were the result of a custom mapping routine to create a custom tuning for that particular piano at that time.
These tunings… Continue reading
The new Sanderson Accu-Tuner Max "980" has 980 pages of memory - more than double the number of available pages of the standard SAT IV. Continue reading
DOB allows us to easily stretch or contract a template or tuning stored in the SAT. A DOB setting of .1 expands the double octave - increasing the beat rate of the double octave - by one tenth of a beat per second. A negative or minus DOB setting contracts the width of the double octave thereby decreasing the beat rate of the double octave in one tenth beat per second increments. DOB can be used where ever more or less stretch is needed. DOB is a feature found on the Sanderson Accu-Tuner III and IV. Continue reading
This article addresses the potential 'Tenor' partial change issue found in all FAC Tunings, and describes a method for checking and correcting it. Continue reading
For those without Accu-Tuners, or for those with older Accu-Tuners without the Piano Librarian software, the download package may still be of interest. In addition to the tuning files in the .sat format, the download package also contains the templates in the Excel Spreadsheet format, for opening with Excel or any other spreadsheet program.
The Accu-Tuner allows the technician to become as involved as he wants in the tuning process. The Accu-Tuner is a sophisticated and accurate pitch measuring device, Continue reading
