2.2.1 Using the installed instrument programs
Whenever the unit is switched on, it
is initially in the instrument selection
mode. From there one can select
one of the instrument programs with
the help of the “Actual” button.
2.2.1.1 Piano
The selection of the optimal stretching depends on various parameters of the instrument to be
tuned. The individual preferences of the musician also play a vital role.
The three built-in stretchings found in the system are the result of trials, during which various pi-
anos were tuned by ear, and subsequently measured. The stretching most suited to match your
particular requirements must be tried out by you first. For your first attempts, we recommend that
you try the stretching 3. For this please apply the following:
Select the instrument program "PIANO_SRETCH_03" with “Actual” button and confirm with “En-
ter”. Indication:
Press “Enter” once more and the unit will switch to the desired tuning program.
The display now shows the concert pitch in brackets. If you were now to play the note ‘a’, the pro-
gram’s concert pitch is automatically adjusted to the note played. If you chose to measure the con-
cert pitch very precisely, you can bring the strobo display to a halt by repeatedly pressing the
“Value” button. The concert pitch now can be read and thereafter adjusted. When applying this
function, the current concert pitch should be not more than 10 Hz higher than the previously se-
lected one, in order to avoid warping the instrument or tearing strings during the tuning task.
You may now begin with the actual tuning by starting with the tone a–1 and aligning all 3 strings of
the chorus. Next follows g#–1, g1, f#–1, etc.
The deviation from the standard tuning caused by tone stretching is shown in cent above the
„Value“-button.
For the two lowest octaves, the partial tone mode changes to the second or the fourth partial tone.
For this reason, it is important that the tuning set always has the correct octave setting. The best
way to avoid inaccurate settings is to progress in steps of semitones while tuning the instrument.
After finishing the tuning of the bass, the discant is tuned by starting with b-1.
2.2.1.2 Organ equal temperament (ORGAN_EQUAL_TEMP)
The selection of a historical temperament, before entering into the tuning program is omitted here.
The settings of cents, partial note and microphone amplification will be preserved while changing
the note.
The thermosensor reference is fixed to 20°centigrade, the cent rate is fixed to 3.2 Cent per degree
centigrade. (Thermosensor reference and cent rate see chapter 2.3.3.6 and 2.3.3.7. The pipe
length reference value is set to 391.0 mm (see chapter 2.3.3.10 and 4.6)
