Polyphony

The polyphony supported by a synthesizer, in other words, is the number of “voices” (tone generators) that can simultaneously sound on it.

This parameter is often described as the number of notes that can be played simultaneously on the keyboard. However, this is not entirely true due to the fact that in many timbres one note can activate several tone generators. As a result, for example, to play a chord of 3 notes in a timbre with 4 tone generators per note, polyphony of at least 3 * 4=12 voices is required. In addition, Auto Accompaniment and Preset Songs (see related sections) also use tone generators, requiring even more voices to work effectively with these features.

The minimum value for a more or less functional modern synthesizer is polyphony for 32 voices — and even then such an instrument can be used mainly for initial training and simple melodies. For a more solid application, it is desirable to have at least 50 – 60 voices, and in professional models (in particular, workstations where you have to deal with several audio tracks at once), there are models with polyphony for 150 tone generators or more.

In general, a more advanced synthesizer is likely to have more extensive polyphony, however, it is only possible to evaluate the class of an instrument by this parameter very approximately — instruments with the same number of voices can differ greatly in level. The only exception to this rule are children's synthesizers (see "T...ype"), which support up to 20 voices.

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.

User timbres

The number of memory slots for user tones provided in the synthesizer.

For Voices in general, see “Preset Voices” above. User timbres are sound settings that were not originally provided in the synthesizer's memory and are created by the user according to their preferences. This feature is indispensable in cases where the built-in set of timbres does not contain the necessary options. However, the capabilities of the User Voices may vary from model to model. So, one instrument only allows you to edit and supplement existing timbres (for example, add a “wah-wah” effect to a bass guitar and save such a bunch as a user setting), another makes it possible to set the sound parameters almost manually, and the third even allows you to load timbres through USB (see below).

The more user timbres in the synthesizer, the more personal “instruments” you can register in its memory.

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.

Custom styles

The number of user auto accompaniment styles supported by the synthesizer, in other words, the number of additional styles that can be stored in memory in addition to the built-in ones. Note that styles can have different volumes (depending on the number of notes used), so this parameter often turns out to be not exact, but only an average-approximate one.

Modern synthesizers may have a fairly extensive set of built-in auto accompaniment styles (see above), but even the richest set may not contain the desired melody. Thus, many models allow you to supplement the standard list with custom melodies. The addition methods themselves can be different: in some models, these melodies need to be downloaded from external media, in others they can even be composed manually. Nevertheless, the presence of user styles allows you to expand the range of auto accompaniment melodies, moreover, at the request of the user himself.

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.

Pitch controller

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

This function allows you to smoothly change the pitch by a small amount. In this way, specific playing techniques on some instruments are imitated — for example, tightening the strings on a guitar, which gives a characteristic, “floating” sound in frequency. The pitch control usually has the form of a wheel or lever.

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.
