Keys

The total number of keys on the keyboard.

The more keys provided in the design, the wider the instrument's own range, the more notes it can play without resorting to octave shift or transposition. On the other hand, this characteristic directly affects the dimensions and cost, and an extensive range is not required so often. Therefore, 88 -key instruments corresponding to a full-size classical piano keyboard are quite rare. But compact models with only 25 keys(2 octaves), on the contrary, are popular: for the purposes for which MIDI keyboards are used, this is often quite enough. Other common options are the 49 -key (4 octave) and 61 -key (5 octave) models; somewhat less common are 32 and 37 keys.

Sustain

The presence in the keyboard of its own sustain control — the extension of the extracted note. With sustain on, the note continues to sound (slowly decaying) even after the key has been released—similar to depressing the right pedal on a piano. Note that many keyboards allow the connection of pedals, including to control this function (see "Connected Pedals"), however, here it means its own controller, which allows you to turn sustain on and off using the keyboard itself, without additional equipment.

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.

MIDI out

A specialized output for transmitting MIDI signals to an external device — a sequencer, a computer sound card (if there is a MIDI In input), etc.

MIDI signals are a kind of "digital notation": they tell which key was pressed, with what force and for how long, and also carry information about various additional parameters: timbre, tempo, key, etc. To convert such signals a "ready" sound requires an external sequencer (software or hardware).

Note that despite its specialized purpose, the MIDI Out output is not mandatory for modern MIDI keyboards: MIDI signals can also be transmitted via other interfaces, such as USB or Bluetooth (see the relevant paragraphs). So it makes sense to specifically look for a keyboard with such a connector if you plan to connect it to equipment with a MIDI In input.

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).
