Rigidity
—
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).
Backlight
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.
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.
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.
Sequencer (recording)
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.
Timbres layering
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.
Octave shift
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.
Arpeggiator
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.
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.
