Aftertouch
The presence of the aftertouch function in the keyboard (aftertouch). The essence of this function is to track the pressure force on the key after it is pressed. In fact, this means that in models with aftertouch, you can control the sound not only due to the force and speed of pressing the key, but also due to the change in pressure on it after pressing; this gives additional features and allows you to use various specific tricks of the game. The specific ways of changing the sound “tied” to aftertouch can be different, depending on the synthesis settings set: for example, when recording a guitar part, you can tie a small change in tone to this function and imitate string bending, when recording a saxophone, change the volume of notes, and etc.
Relatively inexpensive models use a common sensor to monitor aftertouch, which monitors the average force of pressure on all keys pressed; in more advanced ones, separate sensors are installed for each key.
Keyboard split
The presence in the device of the function of splitting the keyboard.
This function, as the name suggests, allows you to divide the keyboard into two parts, each of which will have a different timbre. Thus, on one device, you can play the part of two instruments at once (for example, add the sound of a string orchestra to the violin) or accompany the part of the instrument with various effects (siren, klaxon, thunder, etc.). Some models allow you to select the position of the border between the keyboard zones.
Arpeggiator
The presence of an
arpeggiator in the keyboard.
The name of this function comes from "arpeggio" — a technique for playing chords, in which notes are not played all at once, but in turn. Accordingly, the arpeggiator is a function that allows you to play a taken chord in the arpeggio technique: the musician presses all the keys at once, and the keyboard plays them in turn. This effect can also be achieved manually, but in some cases the arpeggiator turns out to be more convenient: it plays notes at a clearly defined speed and interval, can accompany them with various effects, and provides other additional features. These features vary depending on the model, but some instruments allow you to create entire songs with the arpeggiator by simply pressing a sequence of chords.
Pads
The number of
pads provided in the design of the keyboard.
Pads are auxiliary controls in the form of characteristic pads, usually square. The pads respond to touch, each of them can be tied to a specific sound or even a sequence of sounds. One of the most popular ways to use pads is to play drums or other rhythmic instruments.
