Transposition
The presence of the transposition function in the keyboard — switching the sound to a different key. When transposing, the pitch of all keys is simultaneously raised or lowered by a certain number of semitones. This function is useful in all cases when a melody learned in one key needs to be played in a different key — for example, if the original melody is too high or too low for the vocalist, if the external accompaniment differs in key, if you need to switch between keys during the song, and etc. In such situations, by transposing the sound, you can play a melody in a new key using the same familiar keys without relearning it.
Transport control
The presence in the keyboard of
the transport control function.
In this case, we are usually talking about support for the MIDI Machine Control standard, designed to control external recording and playback equipment. Such support actually turns the keyboard into an external remote control, allowing you to give commands from it to "Play", "Stop", "Pause", "Rewind" (forward and backward) and "Record". To do this, the design provides a separate panel with a set of appropriate buttons.
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.
Faders
The number of
faders provided in the design of the keyboard.
A fader is a slider control. The simplest kind of such controls is the volume setting; if there is one fader in the design, most likely it is responsible for the volume. If there are more controls, other functions can be tied to them, respectively — in particular, changing the settings in the recording programme on the computer to which the keyboard is connected.
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.
MIDI in
Input for receiving MIDI signals from an external device such as an optional keyboard or other controller, sequencer, etc. For MIDI signals, see “MIDI Out”; here we note that such signals received at the
MIDI In input can be mixed with signals from the keyboard and output via MIDI Out or another interface of a similar purpose, or they can be sent unchanged to the MIDI Thru output. It is worth looking for a device with this input if you plan to build a complex from several MIDI signal sources and intend to use the keyboard as an intermediate link in such a system.
Connectable pedals
The maximum number of pedals that can be connected to the keyboard at the same time.
Pedals are used as additional controls to change various keyboard settings. The “classic of the genre” in this sense is the sustain pedal (see “Sustain”) — if the device has
one connector for pedals, then this will almost certainly be the input for just such a pedal. Keyboards are produced, where there
are 2 or more such inputs — in addition to sustain, you can connect pedals to them for other adjustments and effects (in particular, changing the volume).
Tablet stand
Holder for a tablet computer or smartphone in the design of a MIDI keyboard. Usually, this is a device on which the gadget is installed almost vertically (with a slight tilt back).
The stand replaces the music stand for the music displayed on the screen of mobile devices, and it also provides a comfortable placement for a connected tablet or smartphone.
Laptop stand
A pad for placing a laptop, built directly into the body of a MIDI keyboard. It is a retractable shelf, often with an anti-slip surface to prevent the laptop from falling. Together with a laptop, you can always have your own electronic studio at hand.
