Built-in timbres

The number of built-in sounds provided by the Digital Piano.

Despite the name, digital pianos are extremely rarely designed to imitate the sound of only a piano — the electronic hardware allows them to provide other timbres of sound. In addition, even the piano has its own varieties — for example, among the grand pianos there are 6 main classes, from large concert to miniature. So the built-in sounds can cover different kinds of pianos, as well as other instruments and sound effects.

The abundance and variety of timbres in digital pianos as a whole is not as great as in synthesizers, however, in this category there are very “charged” models, with a hundred timbres or more (in the most multifunctional, this number can exceed 900). However, it is worth specifically looking for a “multi-instrumental” model if you do not intend to be limited to the sound of the piano and would like to have more freedom of choice. It is worth remembering that a specific set of timbres can be different.

If the instrument is bought exclusively as a piano, then here, on the contrary, it is worth paying attention primarily to solutions with a small number of timbres. Such models are not only cheaper than "universals" — they can also sound better (due to the fact that there are few timbres and the manufacturer can carefully approach the sound quality of each built-in "instrument").

Auto accompaniment

Auto accompaniment feature on the digital piano.

Auto Accompaniment is a melody of a specific style played by the instrument under user control. Such control is carried out by the left hand: the musician takes certain chords on the left side of the keyboard, and the electronics of the instrument adjusts the auto accompaniment melody to the key of the taken chord. Thus, this function allows you to accompany the main part with a full-fledged accompaniment, while the musician only needs to set the chords.

Among digital pianos, unlike synthesizers, this function is rare. This is due to the general specialization of this class of instruments (not least professional music-making, including as part of an ensemble or orchestra). However, auto accompaniment is available on both relatively simple and high-end digital pianos.

Accompaniment styles

The number of Auto Accompaniment Styles (see above) originally stored in Digital Piano memory.

Different auto accompaniment styles differ from each other in the same way that different melodies differ from each other — in tempo, time signature, rhythmic pattern, set of instruments used, etc. Accordingly, the more styles initially available in the instrument, the wider the choice of the musician and the higher the probability of finding the option that best suits a particular situation. However even numerous styles does not guarantee that among them there will be a suitable one; in addition, we note that with the same number of styles, their specific set in different instruments can also be different. However, custom styles can be provided for this case (see below).

Summarizing, we can say this: if you plan to work intensively with auto accompaniment, in addition to the number of styles, it will not hurt to clarify their specific range.

Tempo change

The range over which the tempo of the sound played by the instrument can change. It can be either a built-in melody or a part recorded on a sequencer, or an auto accompaniment, a tutorial or a metronome. For more information on all of these features, see the corresponding glossary entries. Here we note that a change in tempo is often required in fact — for example, to speed up an initially "sluggish" accompaniment or slow down a training programme that is difficult to master at the original tempo.

Tempo is traditionally indicated in beats per minute. The classical, "academic" range covers options from 40 bpm ("grave", "very slow") to 208 bpm ("prestissimo", "very fast"), however, in modern digital pianos, the working range of tempos is often significantly wider.

More features

Additional features and sound customization options provided by the instrument in addition to those listed above. In this paragraph, usually, various original proprietary technologies and solutions are indicated; the specific meaning of these functions is best specified in the documentation for the tool.

Connectable pedals

The largest number of pedals that can be connected to the Digital Piano at the same time.

Pedals are an indispensable element of equipping a traditional piano, respectively, they are also necessary for electronic analogues of this instrument. However, in stationary devices (see "Body") the pedals are made built-in (see above), so this option is found only in portable models. Also note that if a stationary digital piano has 3 pedals as standard — like in a real piano — then portable digital pianos often have fewer. This is due to the fact that a full set of three pedals is rarely required in fact, and in many cases just one is enough (especially since many instruments allow you to reconfigure its functions).

In general, it makes sense to specifically buy an instrument with three connected pedals mainly for demanding professional musicians who value the full functionality of the pedals (or the ability to tie an extended set of functions to the foot control). In other cases, this parameter is not particularly important.

Outputs

USB to host (type B). Connector for connecting a digital piano to a computer using the USB standard; in this case, the instrument plays the role of a peripheral device. The possibilities of such a connection can be different: recording live music, updating firmware, voices and auto accompaniment styles, using the digital piano as an external MIDI keyboard, fine-tuning the instrument and troubleshooting, etc.; specific functionality varies from model to model.

MIDI out. An output that allows you to broadcast MIDI signals (MIDI events) from the Digital Piano to external devices. A MIDI signal is, in fact, a "preparation" of sound: a signal generated when a key is pressed and containing information about the note number, duration, and force of pressing. Based on this signal, the electronics of the instrument (or other device) generates the sound of a certain timbre. The MIDI output can be useful for connecting a digital piano to, for example, an external sequencer for recording, or to a synthesizer for playback in a tone that is not in the piano itself.

MIDI thru. Output used for switching MIDI signals. The description of such signals is given above, but here we note that the MIDI thru output duplicates the signals received at the MIDI input of the digital piano. This function can be useful in some specific cases — for example, connecting several electr...onic instruments together.

Built-in acoustics

The power of the native acoustics installed in the Digital Piano.

This indicator directly affects the maximum volume that the instrument is able to produce "on its own", without connecting external speakers. At the same time, it is worth noting that many manufacturers go to the trick and indicate in the characteristics not the rated power (rms power when operating at full volume), but the peak power, which is the highest power that the acoustics can deliver at short “ups” of volume. Peak power values can be quite impressive — in the tens and hundreds of watts — but these figures have a very indirect relation to the actual capabilities of the speakers. Therefore, before choosing, it is worth clarifying what kind of power is mentioned in the characteristics. To do this, it is not necessary to look for detailed data on the instrument, it is enough to compare the power of the speakers with the power consumption (see below): if the claimed power of the acoustics is greater than the power consumption of the entire instrument, then the manufacturer indicated exactly the peak value.

Power consumption

The power consumed by the tool during normal operation.

The cost of electricity, as well as connection requirements, depend on this indicator. At the same time, we note that digital pianos require relatively little energy — even in the most powerful and advanced models, consumption usually does not exceed 60 watts. So in fact, power consumption data is required mainly for specific cases — for example, to calculate the total load when connecting a tool to an autonomous generator along with other devices. In addition, this information may be useful when assessing the power of the built-in speaker, for more information, see "Built-in acoustics".
