Comparison Casio SA-46 vs Casio SA-78

The greater the number of keys — the wider the range of the instrument, the lower and higher notes you can take on it right during the game, without resorting to tricks like octave shift (see below). By comparison, a full size piano keyboard has 88 keys. However, in synthesizers, such an amount is rare, because. the instrument would have turned out to be too bulky and expensive, and not every musician, even a professional one, needs such an extensive range. Thus, 88-key keyboards are used primarily in high-end workstations (see "Type"). For ordinary synthesizers, the standard is 49, 61 or 76 keys ( there are also options for 73 keys) — this is usually quite enough (while the "golden mean" option is considered to be 61 keys). And small children's models can have 32 keys.

Additional items supplied with the synthesizer in addition to the instrument itself.

— Music stand. A stand for musical notations, installed in such a way that the materials on it are constantly in front of the musician's eyes. In modern synthesizers, the music stand can be built-in or removable.

— Pedal. An additional control in the form of a pedal, which can be responsible for a wide variety of functions, depending on the model of the synthesizer. For more information about this, see "Connected pedals", here we note that the presence of a pedal in the kit eliminates the need to look for and select it separately.

— Power Supply. Power supply for connecting the synthesizer to the network. The very possibility of working from the outlet is important for most modern synthesizers. Therefore, the absence of a power supply in the kit means either that it is made internal, or that we have a simple and inexpensive model (usually for children, see "Type"), designed mainly for battery operation and not equipped with a PSU or not providing for it at all connections. An external power supply unit is convenient because it can be disconnected when working from autonomous power sources, saving the tool from unnecessary wires.

— Disk. Optical disk (CD or DVD) with various additional materials on the synthesizer. These can be instructions and other documentation, drivers for connecting to a computer, specialized software for editing music on a PC,...etc.

— Rack. Own stand for installing the synthesizer on the floor — usually folding, in the unfolded state resembling the letter X in shape. With such a stand, the musician does not have to look for a free table, window sill or other similar place to place the instrument — there is enough free space on the floor. Racks for synthesizers are also sold separately, but it is often more convenient or even cheaper to buy such a device along with an instrument.

— Microphone. The microphone can be used both for singing and for creating samples based on external sounds. However it is worth noting that usually relatively inexpensive synthesizers for beginner musicians are equipped with microphones — it is more convenient for a professional to independently choose additional equipment (including a microphone) to suit their own needs and preferences, without relying on the choice of the manufacturer. Accordingly, the complete microphones themselves usually have rather modest characteristics.

Rated power of the built-in acoustics of the synthesizer.

This indicator characterizes, first of all, the volume at which the instrument's built-in speakers can sound. At the same time, one should not forget that in most cases such speakers are intended rather for individual use — so that the music can be heard by the musician himself and the people in close proximity to him. With this application, high power is not needed for normal hearing; and if you still need a loud sound, you can connect the instrument to an external speaker.

Therefore, it makes sense to pay attention to the power of the built-in acoustics if the synthesizer is planned to be used for more serious tasks than individual listening, and if external acoustics may not always be available.

Rated power consumed by the tool during operation. Modern synthesizers, even the most powerful and advanced ones like workstations (see "Type"), consume very little energy — up to 100 W, and often noticeably less. Therefore, it is rarely necessary to pay attention to this parameter in fact, mainly in rather specific situations — for example, when working from an autonomous generator, when you need to take into account the entire load connected to such a power supply.

Synthesizer operating time from autonomous power supply (see above) without replacing or recharging batteries. This parameter is quite approximate, because. Actual power consumption of the instrument may vary depending on the length of the songs, the duration of the breaks in the game, the volume of the built-in speakers, the additional functions used, and other factors. In addition, the capacity of replaceable batteries can also be different, depending on the brand. However, the run time listed in the specifications gives some idea of the synthesizer's capabilities and how many sets of batteries may be needed for long-term autonomous use.
