Comparison Casio Privia PX-S3000 vs Casio Privia PX-560M

The ability to adjust the sensitivity of the digital piano keyboard.

The sensitivity level determines the volume and sharpness of the sound that the instrument will produce at a certain force and speed of pressing the key. High sensitivity allows you to achieve sharp, expressive sound with significant volume differences, low — relatively quiet, soft and smoothed. And some instruments even provide "zero" sensitivity — when all keys sound with the same volume and dynamics, regardless of the pressing force. This can be useful, for example, to imitate the sound of certain instruments (such as the harpsichord).

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.

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").

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.

The number of User Auto Accompaniment Styles that can be stored in Digital Piano memory at one time.

See above for auto accompaniment and built-in styles. Here we note that these styles may not be enough — after all, the needs of the musician may not coincide with the decisions of the manufacturer. In this case, it is possible to write custom accompaniment styles to the instrument's memory, along with the standard ones. There are many ways to create and record these styles, but most often they need to be loaded from an external source — from a flash drive or computer. However, some models allow you to compose accompaniment manually.

It is worth paying attention to the number of user styles first of all if you plan to work intensively with auto accompaniment.

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.

The presence of a pitch controller(Pitch Bend) in the design of a digital piano.

Such a controller allows you to smoothly change the pitch of the note being played within a small range (usually up to a semitone up or down). In this case, control is carried out using a wheel, a lever, or another similar element that allows the musician to manually adjust the speed and limits of frequency change (including creating the effect of a note “trembling” in frequency). This function allows you to simulate the playing techniques of some instruments (for example, tightening the strings on a guitar) and gives an unusual sound to timbres that were not originally intended to have such effects.

The presence of a modulation controller in the design of a digital piano.

This controller allows the musician to use various techniques related to changing the volume of the sounding note — for example, vibrato with alternating peaks and dips in volume, or individual “bursts” of volume, etc. At the same time, the musician himself controls the speed and amplitude of changes — with the help of a lever, wheel or other similar control element. The modulation controller can give a performance extra "liveness" or specific coloration, and is also used in some artistic techniques.

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.
