Key #1 begins the process of naming and editing a
new stretch file.
Key #2 is visible only from custom user files, and
goes to the Edit sequence for the File name at the
cursor.
Key #3 returns to the STRETCH MENU.
Key #4 activates the selected stretch and returns to
RUN Mode.
The stretch file selected is shown in the upper right
hand corner of the screen as STRCH = xxxx.
Resolution is shown on the second line as 00.0 ¢.
This indicates it is enhanced to be in 0.1 cent steps.

e. The screen shown above would be the first
“page” of the list of preprogrammed stretch charts and custom stretch charts. Use the PITCH UP arrow and PITCH
DOWN arrow buttons to the right of the screen to scroll the cursor through the preprogrammed stretch files. When
the cursor is on the eighth name (right side of second row) on any page of stored stretch files, press the PITCH
DOWN arrow button again and the tuner will display the next page of custom stretch files (if any). Similarly, when
the cursor is on the first name (left side of first row) on any screen of custom stretch files, pressing the PITCH UP
arrow button will show the previous page of custom or preprogrammed stretch files.
When the cursor is on the stretch memory file you desire, press the #4 Function key to select this stretch file. The
tuner will then return to the RUN Mode screen and will be updated to operate using the stretch you have selected.

f. The tuner activates the new stretch file and returns you to the RUN Mode screen. The display indicates the stretch
file you have selected, and also shows enhanced resolution of the tuner. The resolution may later be changed back
to 1 cent, or 0.5 cent increments. Internal accuracy of the stretch file is always maintained to the precise 0.1 cent
values which have been stored in the memory file. When exiting the Stretch Menu, the tuner indicates the
enhanced resolution to denote the accuracy with which the stretch file values are being used by the tuning motor
controllers.
NOTE: The SC-5000 Tuner powers-up in Equal Temperament and with no stretch. During the power-up sequence the
EQUA TMPR file (with the values for Equal Temperament) is input to the operating parameters of the tuner. All deviation
values are set to 00.0 cents (no stretch) - with the full precision of 0.1 cent resolution. Accuracy of the strobe discs is always
correct to 0.1 cents, even when the global cent offset is displayed in increments of 1 cent, or 0.5 cent. The power-up memory
is set to start the tuner with the global cent offset in increments of 1 cent because this is the most easily used mode of the
tuner.
Whenever a stretch file is active under the RUN screen, an indication of the current octave (OCT) of scale note settings that
the unit is referencing from that stretch file is displayed on the third line of the LCD display. The current octave is
never automatically sensed but is chosen at the discretion of the user by pressing buttons "3" or "4" beneath the display.
Specifically, button "3" (OCT-) will decrement the octave setting (octave 7 through octave 0). If held continuously, it
will continue to decrement the setting shown on screen line 3, wrapping back around from OCT=0 to OCT=7. Conversely,
button "4" will increment the octave setting, eventually wrapping from OCT=7 to OCT=0.
