Key size
In this case, the size means the size of the keys in width — the length practically does not affect the game process.
—
Full size. Standard-width keys, as on a traditional piano keyboard. Switching to such a keyboard from another instrument with standard keys does not cause any problems; Also note that this particular option is recommended for complex games. On the other hand, a full-size keyboard can take up quite a lot of space.
—
Small size. Reduced width keys. It is worth paying attention to this option, first of all, if there is not much space for installing the keyboard and compactness is crucial: small keys allow you to reduce the size of the device. In addition, such keys can be useful for people with small hands. But for complex parties, they are worse than full-sized ones.
Rigidity
The hardness of the keys on a keyboard is the amount of resistance they provide when pressed.
—
Unweighted. Very low rigidity: the keys literally "fail" under the fingers. Found mostly in entry-level keyboards; this is due to the fact that unweighted mechanics are inexpensive, but the low pressure resistance makes it difficult to select the optimal pressure and control the dynamics of the sound.
— Semi-
weighted. Keyboards with medium resistance — not as high as on weighted keys, but noticeably higher than on unweighted ones. This option is considered optimal for active keyboards (see "Mechanics"): at a low cost, it gives quite good responsiveness and, with a minimum skill, allows you to accurately control the pressing force.
—
Weighted. Keyboards with high resistance, which is comparable to the resistance of classical piano keys. Note that high effort in this case is an advantage: it allows you to bring the response of the keyboard as close as possible to the response of a classical piano and makes it easier to control the pressure and dynamics of the sound. Actually, by definition, all hammer-action models are made weighted (see "Mechanics"), but among active keyboards this option is rare — due to complexity and high cost.
Regulators (encoders)
The number
of encoder controlsprovided in the design of the keyboard.
Such a knob looks like a rotary knob, with which you can control various functions of the device to which the keyboard is connected — for example, turn the virtual knobs in the programme for recording and sound processing. At the same time, we note that a full-fledged encoder is capable of rotating 360 ° and turning to any angle in any direction, however, keyboards can also contain knobs with a limited rotation sector — they can also be called encoders. None of these options has a clear advantage: in some cases, an unlimited turning sector is more convenient, in others, a limited one.
