Comparison Yamaha PSR-S770 vs Yamaha MOXF6

— Synthesizer. In this case, we are referring to classic digital synthesizers — keyboard musical instruments capable of reproducing the sound of various instruments and sound effects. The functionality of these models can vary greatly — from budget devices with minimal features to advanced instruments suitable even for professional musicians.

— Workstation. High-end synthesizers for professional use, capable of serving as not only a musical instrument but also as a control panel for recording and mixing sound. Therefore, a sequencer (see below) is a mandatory feature of such instruments. Additionally, workstations are characterized by advanced equipment appropriate to their class: it is among these instruments that you find models with full-sized hammer-action (see "Mechanics") 88-key keyboards, the user has access to a wealth of adjustments and connectors, and the sound quality and authenticity in low-cost models are good, while in advanced ones — nearly perfect. However, synthesizers of this type are quite expensive, so combined with their extensive capabilities, they are indispensable tools for composers, sound engineers, and other specialists engaged in both performance and music recording.

— Children's Synthesizer. The features of such instruments are generally clear from the name — these are synthesizers designed for children. Externally, these models differ from "adult" ones pr...imarily in the smaller number of keys (up to 49, often less) and the reduced size of the keys themselves for a child's hand. In addition, the performance characteristics and functionality of children's synthesizers are also, more often than not, more modest: for instance, the polyphony (see below) rarely exceeds 8 voices, and the overall sound authenticity is quite low. However, the educational capabilities of such instruments, on the other hand, can be very extensive, and in general, children's synthesizers are considered a good choice for initial learning.

— Analog Synthesizer. Instruments in which sound is created not through digital processing but by passing through a real electrical circuit. Very simply, the principle of operation of such an instrument can be described as follows: each key, when pressed, activates its sound generator at a certain frequency responsible for the desired note, and with additional settings (oscillators, envelope, filters), the musician gives this sound its color. From the user's perspective, the most noticeable difference in an analog synthesizer is the absence of built-in timbres — all details of the sound are manually adjusted by the musician. Analog instruments are more complex to operate, but on the other hand, they allow for effects that are not possible with "digital." Moreover, the coloration of the sound on analog synthesizers differs somewhat. Historically, instruments of this type appeared before digital ones; however, today, they are specialized solutions mainly intended for professional performers and used in specific musical directions.

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.

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 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.

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 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.

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 presence of a built-in metronome in the design of the synthesizer.

A metronome is a device that produces sharp sound signals (beats) at certain short intervals specified by the user. In music, such a device is used primarily to maintain a given tempo. A metronome can be useful both for a beginner musician, for developing a sense of rhythm, and for a professional, for example, when learning a new melody, especially if it is to be played without accompaniment and you will need to maintain the rhythm yourself. In addition, the sound of the metronome can also be used as an effect in musical compositions.

The presence of a mixer in the design of the synthesizer.

A mixer in this case is a device designed to control individual audio channels that make up the sound of a synthesizer as a whole. The list of these channels includes, in particular, the main voice, the layered voice (see “Dubbing voices”), several auto accompaniment channels (main, bass, drums, etc.). With a mixer, the musician can manually control these channels — turn some of them on and off, switch the timbre, tempo, key, etc. This greatly expands the possibilities for using the synthesizer.
