Comparison Casio Privia PX-S3000 vs Casio Privia PX-S1000

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 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.

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 presence of an arpeggiator in the design of a digital piano.

The arpeggiator is able to decompose a chord taken on the keyboard into separate notes and play them sequentially, one after another (in the arpeggio technique — hence the name). Using an arpeggiator can be more convenient than playing notes by hand for a variety of reasons. Firstly, such a system works very clearly: notes are played strictly at a given tempo and sequence, with a given duration and interval. Secondly, only three notes are enough to recognize a chord, and the number of notes issued by the arpeggiator can be much larger. Thirdly, the executed notes can be supplemented with various effects or even a full-fledged accompaniment; many instruments allow you to create simple, but quite full-fledged melodies due to the arpeggiator alone. Although, of course, the specific features of this function may vary, it's ok to clarify them separately.

— Mini-jack (linear). Any line input is designed to receive an audio signal in analogue format. Such an audio signal can be played back by the instrument itself through the built-in speakers, external speakers or headphones, switched to external equipment (for example, an amplifier or audio receiver), or recorded (if you have a sequencer, see above). In digital pianos, the most popular is the first option — playback; typically, the line-in sound either serves as an accompaniment to the main part or provides additional effects. As for the mini-Jack standard, this is a miniature plug, also called "3.5 mm" and known to many as a standard audio jack on a smartphone, laptop or computer. However, this standard is also very popular in digital pianos — among external signal sources, mini-Jack plugs are generally more common than full-size Jacks.

— Jack (linear). Line input using a Jack type connector (aka "6.35 mm"). In terms of purpose, such an input does not differ from the mini-Jack type input described above. As for the connector, it is almost 2 times larger than the mini-Jack in diameter — however, given the dimensions of digital pianos, this cannot be called a serious drawback. At the same time, the Jack socket provides a better and more reliable connection, with less likelihood of interference. At the same time, for a number of reasons, this type of connector is used somewhat less frequently in digital pianos.

— MIDI in. An...input that allows the Digital Piano to receive MIDI signals from external equipment. MIDI is a standard signal format in electronic musical instruments; such a signal (MIDI-event) is created for each keystroke and contains information about the note number, strength, speed and duration of pressing; these signals can then be recorded and/or played back in a specific tone. The ability to receive MIDI events from external devices can be useful, for example, when playing two keyboard instruments at once (to play all the music on one of them, with better sound quality), or to use the digital piano as an adapter for another instrument that does not having the desired tones. In addition, technically, a MIDI signal can be switched to other devices (see "Outputs — MIDI thru").

— USB to device (type A). USB connector that allows you to connect various external devices to the digital piano. However, most often the range of such devices is limited to "flash drives" and other drives. However, even this functionality can provide very extensive additional features: you can play backing melodies from a flash drive, update user timbres and auto-accompaniment styles (see above) or even instrument firmware, and copy materials recorded by a sequencer to a flash drive (or even write music directly). ), etc. Specific features in different models may be different, this point should be clarified separately.

— Card reader. A device for reading memory cards — usually, the popular SD format. By purpose, this function is similar to working with a USB flash drive (see above), adjusted for the fact that memory cards will be convenient primarily when exchanging data with a laptop — almost all modern laptops are equipped with card readers, which cannot be said about desktop PCs.
