Start now with the measurements (you now measure the second partial of a-1. To do this, play
the note which is automatically adjusted by the tuner (right now a_1) and align the tuners
frequency until the movement of the strobo display is stopped.
For fine adjustment use the "Func" buttons. For rough adjustment, you hold the "S" button and tap
one of the keys "Func". Pressing both buttons, "Value" at the same time, starts an automatic scan.
The audible tone can be used also.
Press „E".
Play the specified note (for the moment again a_1, since you now
measure the 3rd partial of a-1) and align the tuner again. Press "E".
Play the specified note (for the moment again a_1, since you now
measure the 4rd partial of a-1) and align the tuner again. Then
press "E".The tuner will now continue to the next note. It then emits
a short beep and for 1 second „next note" is indicated on the
display.
Play the specified note (for the moment again a_2, since you now
meassure the fundamental tone of a-2) and align the tuner again.
Press "E".
Certainly, you now know how the device pretends the operating steps. Now perform all
measurements.
Important note: When the instrument is grossly out of tune, immediately after the tuner changes the
note, you should align the actual tone to the tuner using a tuning hammer. This is necessary
because the inharmonicity of the piano string depends on its tension. This, however, only be
carried out immediately after the change of tone. So just before the measurements 5 / 9 /, 13 / and
17/
After the last measurement you get this display. This are eight cents-
values (support values), that were determined automatically on the
basis of previous measurements.
Press "E". The device calculates the piano stretching and stores
them. To start with the real work of piano tuning, search the function
"tune" with the "note" buttons. Then it goes on, as described in
Section 3.5 of the manual for CTS-7.
Note: Within the "PIANYZER"- procedure, you can back step using the "Note" buttons.
3.10.2 How to produce a stretching by entering of support values (Piano Editor)
The tones with the cent's for calculating the stretching, the sake of simplicity, will be referred to
as "support note". Using the piano editor, the cents of the support-notes, you can enter by
hand, rather than be determined by the analyzer (see sample diagram at the end of the
chapter).
Note: The piano editor allows you to edit the cents of the supporting notes, which were
previously generated by the piano analyzer.
