CONCERT CDP2400USB User Manual 9
Using the pedals4.3
The CDP2400USB is equipped with three foot pedals performing
the same functions as the pedals on an acoustic grand piano.
Normally, the pedals are used in accordance with the instructions
given in the music, where they are marked by special symbols. It
is useful to know how sound is produced on an acoustic piano to
better understand how the pedals work.
When you strike a key, a hammer hits several strings for each note;
the strings produce a tone with a defined pitch. When you let go
of the key, a damper felt falls down on the strings to stop them
from vibrating any longer. As a result, the tone decays quickly.
However, if the key is held down, the tone is sustained for a while
before it decays completely. In this case, the tone decays only after
a certain time.
This decay characteristic can be influenced using the three
foot pedals.
Soft/piano pedal (left): • The soft pedal produces a soft and
intimate sound. Use this pedal for particularly soft musical
passages (pianissimo).
On an acoustic piano this soft sound results from a smaller
distance between hammer and strings. On a grand piano,
however, the position of the hammer changes, so that the
hammer does not hit all strings.
Press the pedal to dampen all tones played afterwards with1)
the pedal down.
Let go of the pedal for normal playing.2)
You can adjust the effect of the damper pedal ◊
(see chapter 5.6.2).
Sostenuto pedal (middle): • Use the sostenuto pedal to
sustain individual tones. The notes already played – as
long as they have not yet decayed – will be sustained
as soon as you press the pedal. All notes played
subsequently will be dampened as described above.
This allows you to play and sustain a certain note using
the pedal, while all subsequent tones will be played in a
staccato (detached) manner.
When you sustain single notes on an acoustic piano using
the sostenuto pedal, the damper felts of the notes already
played do not dampen the strings when you release the
keys, but are held in their position.
Play the notes to be sustained.1)
Press the pedal to sustain the tones you just played.2)
Play the next notes. These are played with normal decay.3)
Release the pedal for normal playing.4)
Damper/Forte pedal (right): The damper pedal allows •
you to sustain the notes already played (and held) plus all
subsequent notes, without having to hold the keys down.
The damper pedal is often used to achieve a richer sound.
This is the pedal that is used most often. You can also
use it very subtly, for example, by holding it down only
half-way.
On the acoustic piano notes are sustained by keeping
all the damper felts in their raised position even after
releasing the keys.This allows the notes played to decay
quite naturally.
Play the notes to be sustained.1)
Press the pedal to sustain the notes you just played plus all2)
subsequent notes.
Release the pedal for normal playing.3)
Using headphones4.4
The CDP2400USB is equipped with two headphone jacks located
on the underside of the playing console (front left). Headphones
are ideal for practicing without disturbing others. The second
headphone jack allows another person, for example a music
teacher, to listen as well so that piano lessons can also be held using
headphones. Both ¼" and /" inputs are available.
Use the VOLUME control to turn the volume down (move the1)
slide control to the left half of its control range).
Connect your headphones to a free headphone jack on the2)
underside of the playing console.
While playing, adjust the volume as desired using the3)
VOLUME control.
If required, the4) button allows you to switch the built-in
loudspeakers of the CDP2400USB on or off.
The built-in loudspeakers of the CDP2400USB are switched ◊
off as soon as you connect a pair of headphones; the MUTE
LED above the button lights up.
When you disconnect your headphone from the ◊
headphones jack, the built-in loudspeakers of the
CDP2400USB are switched on again and the MUTE LED
above the button goes out.

Advanced operation5.
The following chapters provide information on advanced operating
functions of the CDP2400USB.
Using EDIT mode5.1
Many advanced operating functions of the CDP2400USB are
available in EDIT mode. The following sections describe how to
adjust these functions in EDIT mode.
Whenever you are prompted to enter EDIT mode, please ◊
follow the step-by-step instructions given below to select a
function and adjust its parameters.
Keep pressing the MODE button in the TEMPO/EDIT MODE1)
section until the EDIT MODE LED lights up.
Scroll through the functions using the Down/Up buttons, until2)
the appropriate function (e.g. E1) has been selected.
Use the -/NO- and +/YES buttons in theVALUE/SONG section3)
to adjust the value of your choice.
Quick access to layer mode functions5.1.1
Use the following operating procedure for direct access to the layer
mode menu pages.
Press and hold down the two sound buttons selected for layer1)
mode (e.g. GRAND 1 and STRINGS) and press the MODE
button in the TEMPO/EDIT MODE section.
The EDIT LED lights up and the EDIT page E3.1 is displayed.
Transposition5.2
The sounds produced by the CDP2400USB can be transposed up
or down by half-tones (key by key). This is useful, for example if you
want to play a piece in a key that is easier to play because it has few
or no accidentals at all (e.g. C major), but intend the piece to sound
in a difficult key with lots of accidentals (e.g. D flat major).
Example: D flat major has five flats (accidentals). In this key you
would have to play a lot of black keys. However, if you transpose
the sounds up by one half-tone, you can easily play the piece on
the white keys (C major). It can be helpful to transpose the
keyboard by an octave (12 halftones), for example to play low notes
in the middle register where they can be played more comfortably.
Press and hold the TRANSPOSE button and use the -/NO and1)
+/YES buttons in the VALUE/SONG section to adjust the
transposition value of your choice in half-tone steps.
The display reads:
0: No transposition (default setting)
1 ... 12: Keyboard is transposed up by the number of half-
tones selected.
-1 ... -12: Keyboard is transposed down by the number of
half-tones selected.
Release the TRANSPOSE button when the desired value has2)
been selected.
+
+

ENGLISH
CONCERT CDP2400USB User Manual 11
The LED above the TRANSPOSE button lights up when the ◊
transposition feature is active, i.e. when a value other than
zero has been set.
If a transposition interval has already been set, you can ◊
enable/disable the transposition function using the
TRANSPOSE button.
Layer mode settings5.3
In layer mode you can effect additional settings for advanced
playing with two sounds at the same time.
All sounds are numbered internally from 1 through 14. This order of
sounds determines which sound is addressed internally as voice #1,
voice #2, etc., which in turn is important for making changes to the
sounds selected.
In our example the two sounds GRAND 1 and STRINGS are being
used in layer mode. Internally, GRAND 1 is #1, STRINGS is #11. The
sound with the lower number is addressed internally as voice #1
(here: GRAND 1), the sound with the higher number as voice #2
(here: STRINGS).
Please note the order of voices used in the sound ◊
combination selected, in order to understand which
settings apply to which voice in the examples below.
A layer combination consisting of two sounds must be set ◊
up before you can adjust the following functions
(see chapter 4.1).
Volume ratio5.3.1
Use this function to adjust the volume ratio of the selected sounds.
Please enter EDIT mode (see chapter 5.1) and select the ◊
following function.
Function: E3.1
Value: 0 . . . 20
Description:
10: Same volume for voice #1 and voice #2
<10: Voice #2 louder than voice #1
>10: Voice #1 louder than voice #2
Detune5.3.2
This function allows you to detune the selected sounds slightly
against each other.
Please enter EDIT mode (see chapter 5.1) and select the ◊
following function.
Function: E3.2
Value: -10 . . . 10
Description:
0: Same pitch for voice #1 and voice #2
<0: Voice #2 higher than voice #1
>0: Voice #1 higher than voice #2
Transposition5.3.3
Use this function to transpose the selected sounds up or down
by one octave. Depending on which sounds are used in a

Tunings5.5.4
The CDP2400USB 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 19th 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 CDP2400USB provides the following tunings:
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 19th century, as it makes
it possible to play all twelve major/minor keys.
+

ENGLISH
CONCERT CDP2400USB User Manual 19
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.
This tuning can only be used for music that strictly follows a
classical cadence comprising tonic, dominant and subdominant.
Pythagorean tuning •
The Pythagorean tuning is based on perfect fifths. As a
consequence, all thirds are impure.
This tuning was used for early music up to the late Middle Ages. The
homophonic or two-part polyphonic music of the time did not use
any thirds, but only perfect unison, fourth, fifth and octave intervals.
Meantone tuning •
Meantone tuning resulted from the change in the perception of
dissonant intervals during the Renaissance period and from the
beginnings of chromaticism and polyphony. Polyphony made the
third the most important interval in music.Therefore, meantone
tuning is based on perfect thirds rather than perfect fifths to tune
the twelve notes of a scale. However, this also means that some
scales are unplayable.
Today, the meantone tuning can still be used for works from the
early 16th and 17th centuries (e.g. G. F. Handel).
Werckmeister/Kirnberger tuning •
The Werkmeister and Kirnberger tunings result from first attempts
to realize a well-tempered tuning which – unlike the Pythagorean
and meantone tunings – allows for playing in all twelve keys. The
advantages of the Pythagorean and meantone tunings, i.e. the
slight detuning of some fifth intervals, have also been included in
the Werkmeister/Kirnberger tunings.
Both tunings are interesting to use for works from the baroque
period (e.g. J. S. Bach). Werkmeister is a popular tuning for
organ works.
The following section describes how to change the tuning of the
CDP2400USB.
Please enter EDIT mode (see chapter 5.1) and select the ◊
following function.

With the exception of equal tuning, all tunings must be marked by
a basic note.
Here’s how to set the basic note:
Function: E2.2
Value: C . . . B
Description:
Altered notes are marked by dashes above or below the note name.
A dash above the note name raises a note, a dash below the note
lowers it.
