Comparison Yamaha EZ-310 vs Yamaha PSR-E373

— Unweighted. Keys with a very low pressing force, literally "failing" under the fingers. This option is well suited for inexpensive synthesizers with passive mechanics (see above), but is rarely used in active models — a small resistance force makes it difficult to choose the optimal pressing force.

— Semi- weighted. Medium-strength keys, not up to the hardness of a full-fledged piano, but showing noticeably more resistance than unweighted ones. This variant is most popular among instruments with active mechanics (see above) — the force on the keys provides adequate feedback and at the same time playing such an instrument does not cause any special difficulties even for those who previously dealt only with unweighted keyboards.

— Weighted. Keys with high actuation force, comparable to that of a classical piano. Used only in professional hammer action instruments (see above) — high rigidity is a must for such mechanics (more precisely, for the response that it must provide).

The presence of a backlight in the design of the keyboard.

Usually, in this case, the illumination of each individual key is implied. This function is not of great importance for ordinary music-making, but it can be very relevant when learning: the instrument can highlight the keys that need to be pressed at the moment, simplifying the task for the student. Actually, the presence of a backlight is most often just a sign of the presence of a training mode in the instrument (see below), although not every “training” synthesizer has this function.

The number of built-in sounds provided in the synthesizer.

The number of timbres is often described as the number of instruments that a given model can imitate. However, this is not entirely true — rather, this parameter can be called "the number of instruments and sound effects." For example, the same instrument — an electric guitar — with different "gadgets" (distortion, overdrive) will sound differently, and in the synthesizer each such gadget will be considered a separate timbre. The “drums” timbre usually combines different types of drums and other percussion instruments — in other words, it allows you to portray both the “bass drum” and the cymbals without switching settings, just by pressing the desired keys. And some timbres may not have analogues among real instruments at all.

The more built-in timbres, the more extensive the possibilities of the synthesizer, the more diverse the sounds that can be extracted from it. At the same time, in high-end models like workstations (see "Type"), this number can reach 1000 or even more.

The number of auto accompaniment styles (see above) originally provided in the synthesizer, in other words, the number of accompaniment options available to the user.

The more extensive this set, the higher the probability of finding among these melodies suitable options for a particular case. At the same time, the abundance of styles in itself is not yet a 100% guarantee that among them there will be a suitable one, especially since different synthesizer models can differ markedly in a specific set of melodies. So the list does not hurt to clarify before buying. Also note that the situation can be corrected by user styles (see below) — many synthesizers with auto accompaniment support them.

The sequencer is a device that allows you to record music played on the instrument in real time. Recording is usually done in MIDI format. At the same time, the capabilities of the sequencer can include not only the recording and playback of the music being played, but also advanced options for editing it: sequential overlay of several parts, mixing of recorded tracks, changing the volume, tempo, timbre, key of the recorded compositions, quantization to eliminate tempo irregularities, etc. .P. The specific capabilities of the sequencer, usually, directly depend on the type (see above) and the price category of the synthesizer. However, anyway, this function can be an important help for both a novice musician and a professional.

Synthesizer support for octave shift function.

This function allows you to shift the sound of the instrument one or more octaves up or down — for example, so that the keys of the first octave sound the notes of the second, or vice versa. This function can be used for both simple convenience and more practical purposes — it allows you to play very low and very high notes that are not initially covered by the keyboard range. This is especially useful for shortened 49- or 61-key synths that do not initially fit the full range of the piano.

— mini-Jack (3.5 mm). Line-level analogue audio input using a 3.5mm mini-jack. The line input itself is used to connect an external analogue audio signal to the synthesizer — for example, from a computer sound card. The use of such a connection can be different: playing accompaniment through the built-in speakers of the instrument, switching the signal to an external amplifier with “mixing” the sound of the synthesizer itself into it, etc. Specifically, the 3.5 mm mini-Jack connector is small in size, it is popular mainly in portable equipment and inexpensive stationary devices — “serious” audio equipment is usually equipped with more reliable connectors, like Jack (see below). As a result, an input with this type of connector is typical mainly for entry-level synthesizers.

— Jack (6.35 mm). Line-level analogue audio input using a 6.35 mm jack. By purpose, such an input is completely similar to the input with a 3.5 mm mini-Jack jack described above, however, the Jack connector is larger, provides a more reliable and high-quality connection and is considered more suitable for stationary audio equipment, especially high-end ones. Therefore, in synthesizers of an average and advanced level, usually, this type of line input is used. At the same time, we note that a 3.5 mm plug can be connected to a 6.35 mm jack using a simple adapter.

— Digital. Input for connecting to a digital audio signal synthesizer. It is similar in purpose to the linear interfaces descri...bed above, but differs both in signal format and in connector type — most often it is a coaxial S / P-DIF interface using an RCA connector, although other options are possible. Digital outputs are quite popular both in professional audio equipment and in home appliances like PCs and even TVs, so such an input may be useful.

— MIDI. MIDI is originally a digital signal format used in electronic musical instruments. Each key pressed on the synthesizer gives just such a signal: it contains data on the duration, force and speed of pressing, as well as the note number, and based on the control signal (MIDI event), the “hardware” of the synthesizer generates the desired sound. Accordingly, the MIDI input allows the synthesizer to receive MIDI events from external electronic musical devices — other synthesizers, MIDI controllers, etc. This connection can be useful, for example, if the external instrument does not have the desired timbre; in addition, many synthesizers are capable of recording received MIDI signals. In some cases, the possibility of switching such a signal via MIDI thru may also be useful (see "Outputs").

— USB (type A). A classic USB connector that allows you to connect various external devices to the synthesizer — primarily flash drives and other drives, other peripherals are rarely supported. The features available when working with a flash drive depend on the general functionality of the synthesizer and may be different in different models. So, some instruments are capable of playing music from such a carrier, which plays the role of accompaniment for the main part — this can be more convenient than using auto accompaniment. Others are able to record music on a flash drive. It may also include updates to the Voice Set and/or Auto Accompaniment Styles (see above), firmware updates, etc.

— Card Reader. A slot for reading memory cards, most often SD: this is a universal format widely used in many types of modern electronics. Like a USB flash drive (see above), the card reader can be used for different purposes — most often for playing musical accompaniment or recording music, but there are other options (loading additional timbres, updating firmware, etc.).

Additional items supplied with the synthesizer in addition to the instrument itself.

— Music stand. A stand for musical notations, installed in such a way that the materials on it are constantly in front of the musician's eyes. In modern synthesizers, the music stand can be built-in or removable.

— Pedal. An additional control in the form of a pedal, which can be responsible for a wide variety of functions, depending on the model of the synthesizer. For more information about this, see "Connected pedals", here we note that the presence of a pedal in the kit eliminates the need to look for and select it separately.

— Power Supply. Power supply for connecting the synthesizer to the network. The very possibility of working from the outlet is important for most modern synthesizers. Therefore, the absence of a power supply in the kit means either that it is made internal, or that we have a simple and inexpensive model (usually for children, see "Type"), designed mainly for battery operation and not equipped with a PSU or not providing for it at all connections. An external power supply unit is convenient because it can be disconnected when working from autonomous power sources, saving the tool from unnecessary wires.

— Disk. Optical disk (CD or DVD) with various additional materials on the synthesizer. These can be instructions and other documentation, drivers for connecting to a computer, specialized software for editing music on a PC,...etc.

— Rack. Own stand for installing the synthesizer on the floor — usually folding, in the unfolded state resembling the letter X in shape. With such a stand, the musician does not have to look for a free table, window sill or other similar place to place the instrument — there is enough free space on the floor. Racks for synthesizers are also sold separately, but it is often more convenient or even cheaper to buy such a device along with an instrument.

— Microphone. The microphone can be used both for singing and for creating samples based on external sounds. However it is worth noting that usually relatively inexpensive synthesizers for beginner musicians are equipped with microphones — it is more convenient for a professional to independently choose additional equipment (including a microphone) to suit their own needs and preferences, without relying on the choice of the manufacturer. Accordingly, the complete microphones themselves usually have rather modest characteristics.

Rated power consumed by the tool during operation. Modern synthesizers, even the most powerful and advanced ones like workstations (see "Type"), consume very little energy — up to 100 W, and often noticeably less. Therefore, it is rarely necessary to pay attention to this parameter in fact, mainly in rather specific situations — for example, when working from an autonomous generator, when you need to take into account the entire load connected to such a power supply.
