7.8 Temperament
The digital piano has a total of three temperament settings that can be set using the
piano keys.
Piano key Meaning
[F4] EQUAL
[G4] JUST MAJOR
Hold down [SHIFT] and press one of the piano keys [F4], [G4] or [A4] to set the
desired temperature. By default, the temperament is set to ‘EQUAL’ .
The equal tempered tuning divides the octave
into 12 equal semitone steps. This tuning has
become standard over time because playing all
keys is equally possible.
A tuning process in which the intervals are
tuned without beat. This creates chords with
great sonority. For physical reasons, this only
works for the major key specied here.
Related chords have low beats, distant chords
(such as F sharp major in a pure C tuning) usu‐
ally sound very out of tune.
[A4] JUST MINOR
A tuning process in which the intervals are
tuned without beat. This creates chords with
great sonority. For physical reasons, this only
works for the minor key specied here.
Related chords have low beats, distant chords
(such as F sharp minor in a pure C tuning) usu‐
ally sound very out of tune.

7.18 MIDI functions
7.18.1 What is MIDI?
7.18.2 USB connection
MIDI stands for ‘Musical Instrument Digital Interface’ and represents the standard
interface between a computer and electronic instruments. You can use the USB port
or the MIDI output socket of the digital piano for transferring MIDI data to a com‐
puter or other USB device.
1. Connect the USB port of the digital piano using a standard USB cable (not
included) to the USB port on your computer.
2. Observe the following instructions when connecting USB instruments to com‐
puters. Otherwise, the instrument or the computer may ‘crash’, which can
result in data loss. If a ‘crash’ should occur, turn o computer and instrument
and restart both after a few seconds.
– If the computer is in standby or hibernation, wake the computer
before connecting the USB cable.
– Establish the USB connection between computer and instrument
before turning on the instrument.

Introduction
Unbalanced transmission
1/4" TRS phone plug (stereo, unbal‐
anced)
Three-pole 1/8" mini phone jack
(stereo, unbalanced)
This chapter will help you select the right cables and plugs to connect your valuable
equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated:
Even if a plug ts into the socket, an incorrect connection may result in a destroyed
power amp, a short circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi
use. Instrument cables with two conductors (one core plus shielding) are typical rep‐
resentatives of the unbalanced transmission. One conductor is ground and shielding
while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at
low levels, such as microphone signals and when using long cables.
