not already exist, the tuner immediately opens a new STRCH file with the name you have selected. The screen
advances to the Edit STRCH sequence.
In the unlikely event that the memory of the tuner is full, you will see an error message of “MEMORY IS FULL
- PLEASE DELETE A TMPR OR STRCH FILE”. The tuner memory capacity is 255 custom TMPR files, or 31
custom STRCH files, or a mixture of both custom TMPR and custom STRCH files. If you see this message
display, it will be necessary to delete one or more custom TMPR or STRCH files in order to enter your new file.
Before deleting one of these useful files, you will probably want to write down the specific values for every
tempered and/or stretched note in the file. In Appendix A and Appendix B of this instruction manual, you will find
blank tables for your hard copy entry of custom temperament files and custom stretch files (with permission to
photocopy these pages). Use the Edit TMPR or Edit STRCH sequence to examine the specific values for each note
in the TMPR of STRCH file you plan to delete. Do not alter any value as you transfer this information to your hard
copy paper record. After you have documented the details of your file it is then safe to delete it and make room
for more custom files.
h. In the Edit STRCH sequence, the stretch value for each note (in Cents deviation from the Equal-Tempered Scale)
is input using the Pitch Up and Pitch Down buttons on the tuner front panel. Entering the selection for each note
overwrites that value into the memory location for that specific note in the STRCH file. The tuner starts with note
C in Octave 4 and proceeds in an increasing sequence through all twelve notes of the chromatic scale in Octave
4, ending on B. Then, following a typical piano tuning order, the sequence proceeds through alternating octaves
above and below Octave 4, gradually widening to the highest (7) and lowest (0) octaves. The first screen display
is:
STRCH = XXXX KEY = C
NOTE = C +XX.X
OCTV= 4
DONE NEXT Key #3 holds values entered - advances screen to save
current STRCH tuning values.
Key #4 enters and holds value - goes to next note.
1 2 3 4
Use the PITCH UP and/or the PITCH DOWN Control to adjust the number of cents deviation from standard, Equal
Temperament tuning for the note C in Octave 4. You may enter this value with a precision of 1/10 of 1 cent. Whenever
you have modified as many Octaves and Note values as you require for your Custom STRCH file, you may exit the
Stretch Edit sequence by using the #3 Function key (DONE) and then the ENTER button. The values you have entered
will be saved and the tuner will return to the RUN Mode, using the programmed STRCH tuning values. Alternatively,
press the #4 Function key when the displayed Stretch file value for Octave 4, Note C is correct. The display will
increment the note to C#.
