Polyphony

The number of voices supported by the digital piano — more precisely, the maximum number of voices that the instrument can play at the same time.

This parameter should not be confused with the number of notes that can be played simultaneously on the keyboard. The fact is that in many timbres, several voices (tone generators) are used for each note at once — this is the only way to achieve a more or less reliable sound. Thus, the required number of voices can be many times higher than the number of notes — for example, the simplest chord of 3 notes may require 9 or even 12 voices. In addition, tone generators are used to play auto accompaniment parts and built-in songs (see below), and here the number of voices can already be measured in tens.

In light of all this, polyphony of less than 90 voices is typical mainly for relatively simple and inexpensive instruments that are not designed for complex tasks. The smallest number found in modern digital pianos is 32 voices. It is desirable for a more or less solid instrument to have at least 96 voices, and in top models this figure can reach 256.

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").

Sequencer (recording)

The presence of a sequencer in the design of a digital piano.

This function allows you not only to play music on the instrument, but also to record it with the possibility of later playback. However, this is at least; in addition to recording the parts of the instrument itself, the sequencer can provide recording an audio or MIDI signal from the corresponding input, mixing several parts (including recording the music being played over the music being played “on the go”), working with the parameters of individual tracks (volume, tone, timbre), as well as specific functions such as quantization (smoothing uneven tempo). The specific functionality of the sequencer may be different, it's ok to check it before buying. However, anyway, this function can be a good help for the musician; it is especially useful for those who are not limited to the performance of ready-made music and want to compose their own compositions.

Keyboard split

Possibility of dividing the keyboard into two parts so that the parts of the left and right hands are played in different timbres. This allows you to simultaneously play two disparate parts on the instrument — for example, accompany a piano melody with chords from a string orchestra or organ sounds. Specific combinations of timbres are most often pre-recorded in memory, however, there are models in which the musician himself can choose timbres for each part of the keyboard.

Octave shift

The presence of an octave shift function in the digital piano.

This function makes it possible to "shift" the sound by a certain number of octaves up or down — for example, in such a way that the bass register sounds on the keys of the first octave, or vice versa, the first octave "slid" lower, into the bass, and notes of the second sounded in its place or even the third octave.

This feature significantly expands the range of the instrument, allowing you to play notes that were not originally covered by the keyboard. This is especially important for instruments with 61 or 73 keys (see "Number of Keys"), but octave shifting is not uncommon in full-sized 88-key models — it can be useful when splitting the keyboard (see above), when available for each hand the range is noticeably reduced, and the batch can be very low or very high. However, there are other options for using transfer — for example, so that when playing an updated version of the melody, you do not have to move from the usual octaves.

Brightness

The ability to change the brightness of the sound of certain timbres or tracks.

Brightness determines the overall colour of the sound — from soft, smoothed to sonorous, sharp. This feature allows the player to adjust this coloration to their preference, and thus further expands the possibilities for customizing the sound of the instrument.

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.

Linear outputs

The number of line outputs provided in the design of the digital piano.

The line output allows you to send the sound from the instrument to external audio equipment. In this case, the sound is transmitted in an analogue format, and to play it, it is enough to pass it through a power amplifier; and active acoustics can generally be connected directly to the line output. The outputs themselves can use different types of connectors, but most often they are 3.5 mm mini-Jack or 6.35 mm Jack, compatible with most audio equipment either directly or through the simplest adapters.

Multiple line outputs allow you to connect multiple signal receivers to the instrument at once — for example, speakers with an amplifier for playback and an external recorder for recording. However, digital pianos rarely have more than 2 line outputs — more, taking into account the specifics of the use of such instruments, is simply not required.
