Comparison Yamaha PSR-E443 vs Yamaha PSR-R200

Type of action used in synthesizer keys.

— Passive. The simplest type of mechanics, when each key is, in fact, a “switch” for its note: it only turns the sound on and off, while the volume of this sound does not depend on the strength and intensity of pressing. Passive keyboards usually have unweighted, less often semi-weighted hardness (see below). Their main and, perhaps, the only advantage is their low cost, due to the simplicity of design. At the same time, the capabilities of such tools are very limited, and even when training, it is recommended to use them only at the very initial stages. As a result, passive mechanics are used exclusively in the simplest low-cost-level synthesizers, which are more suitable for the role of a toy for entertainment, rather than a full-fledged instrument.

— Active. A mechanic that provides a relationship between volume and pressing force: the harder the key is pressed, the louder and sharper the sound will be. Most often combined with semi-weighted, occasionally unweighted hardness (see below). Such keys already make it possible to control the dynamics of each note: select its volume "on the fly", highlight accents, use special techniques, etc. This feature is especially important in training, when you need to train to control the effort on each individual finger. Active mechanics are highly recommended even for an inexpensive synthesizer, and for a mid-range instrument it is almost man...datory, as well as for serious learning. At the same time, many models may provide sensitivity adjustment, or even a complete switch to passive mode (for example, to simulate some instruments).

— Hammerhead. The most advanced kind of mechanics. Like the active one, it provides volume control depending on the force of pressing, but it fundamentally differs in response: hammer action is used only in weighted keyboards (see "Rigidity"), and the feeling when playing it is close to playing on a real piano. The degree of approximation, however, can be different — some models are indistinguishable in sensations from the piano, in others the mechanics are simpler. However, anyway, such features are not cheap, despite the fact that the real need for a "piano" response is extremely rare. As a result, hammer action keyboards are found mainly among top-class instruments, mainly workstations (see "Type") with full-size keyboards for 88 keys.

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 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.

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.

The ability to overlay different timbres of the synthesizer sound on top of each other. This creates the effect of the sound of two (or even more) instruments at once — for example, piano and violin. At the same time, in advanced models, it may be possible to set different settings for different timbres so that the sameness of the extracted notes is not so noticeable — for example, the same "violin" can be set to smooth transitions between notes, while on the "piano" they will sound jerky.

Possibility of dividing the keyboard of the synthesizer into two parts, each of which is responsible for its own timbre of sound. Thus, on one keyboard, you can play two "instruments" at once in real time — for example, accompany the solo part of the violin with chords of a string orchestra. At the same time, unlike auto accompaniment (see above), all notes are taken by the musician himself, without relying on the automatic settings prescribed in the programme.

Usually, several “split keyboard” combinations are pre-written in the synthesizer’s memory, however, some models allow you to separately select a timbre for each half, at the discretion of the musician.

The presence of an arpeggiator in the design of the synthesizer.

The term "arpeggio" originally means the technique of playing a chord, in which the notes are not sounded all at once, but one after another. Accordingly, arpeggiator, roughly speaking, is a device for the automated playing of chords using the arpeggio technique. Compared to manual playback by notes, this function is convenient because the arpeggiator can provide various additional settings: set the direction of playback (up or down), speed, interval between notes and their duration, special effects, background accompaniment, etc. At the same time, all effects work automatically, the user only needs to press the keys that make up the chord (and in some synthesizers in some modes, only one key can generally be responsible for a whole chord). The specific capabilities of arpeggiators can be different, often such a device allows you to create entire compositions just by pressing a sequence of chords.

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.
