USEFUL INFORMATION
At this point, we would like to provide definitions for a few terms that are used in this
manual.
We also explain the special features of your digital piano here.
7.1 INDEX
Term Definition
MIDI
Musical Instrument Digital Interface is a data transmission protocol. That
means that musical control information is transmitted between electronic
instruments such as digital pianos, keyboards, synthesizers, drum
computers and also PCs and laptops. To exchange this control information,
the instruments/computer need MIDI connectors and a connection must
be made between them. There are different MIDI connections with different
functions: MIDI-IN, MIDI-OUT and MIDI-THRU. The latter forwards the
data received via the MIDI input unaffected to another MIDI device.
Example:
When you press a key on the digital piano, small data packages are sent
via its MIDI OUT port. These data packages contain information concerning
the pitch and velocity of the corresponding tone. They can, for example, be
recorded, stored and played back on the computer. Moreover, they can
be transformed into musical notation on screen if there is an appropriate
program.
GM General-MIDI (abbrev. GM) standardises significantly more than the
universal MIDI standard. The latter is both a hardware and protocol
specification. General-MIDI also specifies content. GM sets a minimum
standard for the allocation of instruments on the 128 program slots.
According to GM, a compatible tone generator must be able to produce
24 sounds at a time. According to GM, further control parameters are
defined e.g. the effect control.
General
MIDI Sounds
Sounds or instruments according to the specifications of the general MIDI
standard.
Reverb
The device simulates how the sound in a room would be. This sound
simulation is already preconfigured for some sounds to make them more
realistic.
Chorus
The Chorus Effect adds a copy of the played notes which is slightly
detuned. Therefore the sound seems fuller.
Samples
Samples are sound recordings of instruments. The notes of the instruments
are recorded and stored individually. When you play a note on the
keyboard of the digital piano, the corresponding recordings are played
back.
Polyphony With electronic instruments, the term ‘polyphony’ refers to how many tones
can be played at the same time.
