6.6.1 Key velocity
This parameter determines the volume of the sounds with
reference to the key velocity applied, i.e. you can set here how
hard you have to strike a key to achieve maximum volume.
The following section describes how to change the key velocity.
1) Press the VELOCITY button to select one of the following
settings:
V
HARD:
The keys must be played very hard to achieve
maximum volume.
V
MEDIUM: The keys must be played with medium velocity
to achieve maximum volume.
(default setting)
V
SOFT:
The keys must be played only lightly to achieve
maximum volume.
V
OFF:
If none of the LEDs lights up, each key stroke
will produce a defined volume, irrespective of
how hard you play the keys.
An LED above the button lights up to show the current setting. If
all LEDs are out, key velocity is switched off. In this case you
can adjust a fixed volume level as follows:
2) Press and hold the VELOCITY button, then use the -/NO and
+/YES buttons to set the volume level to be produced when
you play a key on the keyboard, irrespective of the key
velocity applied.
+
The display reads:
1 127
:Fixed volume level produced when you play a key on
the keyboard (default setting:
64
)
3) Keep the VELOCITY button pressed, then press the -/NO
and +/YES buttons simultaneously to recall the standard
setting.
The key velocity setting has no effect on the
following sounds: HARPSICHORD, CEMBALO, JAZZ
ORGAN, CHURCH ORGAN and PIPE ORGAN.
TIP: young pianists might find it easier to use a
SOFT key velocity setting.
6.6.2 Soft pedal intensity
Use this function to adjust the intensity of the soft pedal effect.
Please enter EDIT mode (see chapter 6.1) and select
the following function.
Function:
E4.2
Value:
1 5
Description:
3
:
Normal soft pedal intensity (default setting)
1
:
Low soft pedal intensity
5
:
High soft pedal intensity
The function will be effective only if the left pedal
is used as a soft pedal, but NOT to start/stop the
music sequencer (see chapter 6.5.8).
6.6.3 Fine tuning
The EG8080 can be detuned slightly to adapt it to other instruments
or tunings. The setting made here affects the pitch of all keys.
The following section describes how to adjust the fine tuning of
the EG8080. The tuning shown in the display is referenced to the
concert pitch „A“ in Hertz (Hz).
Please enter EDIT mode (see chapter 6.1) and select
the following function.
Function:
E1
Value:
427 453
Description:
440
:
Western European equal tuning (default setting)

1/5-Hz steps are shown as follows (figures separated by one
or two dots):

6.6.4 Tunings
The EG8080 provides different tunings developed during the
past few centuries. The tuning used most often today is called
equal tuning and has been a characteristic element of the music
composed from the 19
th
century up to the present. However, for
some baroque pieces (e.g. by J. S. Bach) it can be interesting to
use an older tuning system.
In the history of music, the development of the individual tunings
can be traced back to the development of scales and polyphony
and the resulting adaptation of instruments and their tuning. Apart
from these historical reasons the limited tuning aids available in
former times played an important role for the practical
implementation of tunings.
The EG8080 provides the following tunings:
V
Equal tuning (default setting)
Equal tuning divides one octave into twelve intervals of equal
size or spacing. Thus, each half-tone is detuned slightly to the
same extent, with the octave being the only perfect interval. This
has been the most common tuning since the 19
th
century, as it
makes it possible to play all twelve major/minor keys.
V
Pure major/minor intonation
This tuning is based on the perfect tuning of the seven notes of
one scale (e.g. C major). Triads played one fifth above or below
are also perfect, since they use the notes of the basic key.
However, all other keys are not playable, since their frequency
relationships change depending on the basic note.
