Sensitivity adjustment

Ability to change the sensitivity of active mechanics (see above) in the synthesizer.

This function allows you to adjust the intensity of the key's response to pressing. Simply put, the higher the sensitivity, the louder and sharper the sound will be, with the same pressing force. This allows you to change the characteristics of the instrument's sound.

Also in synthesizers with this function, it is often possible to completely turn off the active mechanics and play on a “passive” keyboard. This can be useful for making certain voices, such as harpsichord or organ, sound realistic.

Built-in timbres

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.

Auto accompaniment

The presence of the auto accompaniment function in the synthesizer.

This function allows the instrument to automatically play an accompaniment melody that you can play along with the main part on the keyboard. At the same time, the left hand of the musician can control the accompaniment: it is enough to take a chord on the left half of the keyboard, and the auto accompaniment will automatically “decompose” it into instrument parts that sound in accompaniment. Thus, the musician turns into a "man-orchestra": one synthesizer can replace the whole ensemble, or at least a solid part of the ensemble. Of course, the sound quality in such models can be different, and not every synthesizer with accompaniment is suitable for an event more serious than a children's party, although there are quite advanced models.

In addition, playing to accompaniment can also be useful for educational purposes: it contributes to the development of general technique, a sense of rhythm, and additional accompaniment is very convenient during improvisation exercises.

It should be taken into account that not only the sound quality, but also the number of accompaniment styles (melodies) can be different; and some models allow you to record your own melodies. See below for more details on these features.

Accompaniment styles

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.

Learning mode

The presence of a learning mode in the design of the synthesizer.

The purpose of this function is clear from the name. It is most often based on the following principle: the synthesizer itself tells the student which keys to press, displaying the keyboard on the display or highlighting the necessary keys using the backlight (if available, see above). Of course, at different levels of learning, the format of such prompts will also be different: for example, at the very beginning, the synthesizer highlights the necessary notes until they are pressed, and at the final stage it highlights them at the tempo at which you need to play the melody, and evaluates the accuracy of the student pressing the desired keys. There are also other features and nuances of learning — for example, the mode of separate learning of parts for the left and right hands, when the instrument itself plays one part and tells the student how to play the second. In addition, a metronome function is practically mandatory for a synthesizer with this mode (see below).

Regardless of the specific functionality, this mode will be very useful for those who are just developing their keyboard playing skills.

Tempo change

The range in which you can change the tempo of the programme played by the synthesizer — auto accompaniment, lesson tune (see above), metronome (see below), recorded sample, etc.

Pace is measured in beats per minute. Changing it allows you to adjust the speed of the synthesizer to the specifics of the situation — for example, slightly slow down the tutorial if it is too hard to master at the initial pace. The wider the range of tempo adjustment, the more options the musician has to choose from, especially in the area of very slow and very fast tempos.

Note that the traditional range of musical tempos covers values from 40 beats / min (“grave”, “very slowly”) to 208 beats / min (“prestissimo”, “very fast”), however, in synthesizers it can be more extensive — for example, 30 – 255 bpm.

Chorus

The presence of a chorus effect in the synthesizer.

The word "chorus" comes from chorus, "chorus", and the purpose of this function is quite consistent with the origin of its name — it creates the effect of the choral sound of several instruments. To do this, the original sound signal is copied (one or more times) and the copies are added to the overall sound with a small, up to 30 ms, time shift, and this shift is constantly changing. In this way, a small but noticeable difference in individual "voices", characteristic of a real choir, is imitated. However it is worth noting that a full-fledged resemblance to a choral performance with the help of a chorus cannot be achieved even on the most advanced synthesizer; however, this effect in itself sounds very interesting, thanks to which it does not lose its popularity.

Inputs

— 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.).

Connectable pedals

The number of pedals that can be connected to the synthesizer at the same time.

Pedals are additional controls that expand the capabilities of the instrument. One of the most famous pedal functions, familiar to many from classical pianos and grand pianos, is “sustain”, where the sound continues to sound after the key is released, slowly fading out. However, the matter is not limited to this, the purpose of the pedals can be very diverse: enabling or disabling additional effects, switching between octaves or keys, etc. At the same time, in some synthesizers, mostly inexpensive, the assignment of the pedals is fixed, in others it can be reconfigured to fit your goals.

For most instruments, one pedal is sufficient, but high-end models such as workstations (see "Type") may support multiple connections.
