The Musical Instrument Digital Interface (MIDI) protocol is a means of communication between electronic instruments, such as the portable keyboard, that adhere to the standard, and computers through a MIDI interface. MIDI communication contains various information regarding which notes will be played, when they will be played, how loudly and for how long, the type of sound to be produced, as well as other general control and timing information. To transfer this data between MIDI devices, special MIDI cables are used to connect each instrument or the MIDI unit of the computer. Typically, there are three types of connections – In, Out, and Thru – and all use a common receptacle/plug with 5 pins/5-pin DIN.

• • MIDI In: This connection receives MIDI signals from other devices.
  • MIDI Out: This connection sends MIDI signals to other devices.
  • MIDI Thru: This connection provides control over the signals received at the MIDI In port, allowing multiple MIDI devices to be connected together.

Speakers

As mentioned earlier, most models come with built-in speakers—usually a pair positioned on the edges of the keyboard. A more expensive model may have a more powerful amplifier, ranging from 2W to 6W per channel, and sometimes two-way speaker systems with separate tweeters and woofers for a fuller and higher-quality sound.

The Keyboard

To maintain the portable nature of the instrument, most portable keyboards have 61 keys, spanning 5 octaves, either non-weighted or dynamically sensitive (touch-sensitive). This detail is crucial as a portable keyboard with dynamically sensitive keys is usually suitable even for the early stages of piano practice. This feature mimics how the intensity of each note responds to key pressure. The harder you press a key, the louder the played note, much like a piano keyboard. However, this is only a small step, as the keyboard of a classic or digital/electric piano also has weighted keys, providing even greater realism in the playing experience. All portable keyboards, except for the very inexpensive ones, have full-sized keys, as schools often recommend parents use portable keyboards as an alternative and more economical solution when their child begins to learn the piano. They can use headphones not only to avoid disturbing neighbors but also because the initial cost is not as high as that of a traditional piano, and the regular maintenance costs are avoided. The variety of different sounds and rhythms can also encourage a child to experiment with music and make practice more enjoyable.

Sounds

For similar reasons regarding the basic variety of sounds, all portable keyboards have at least one basic sound of an acoustic piano. Most models cover a wide range of different sounds, such as strings, brass, accordion, bass, synthesizer, and percussion. As you move up to more expensive models within a manufacturer’s lineup, the instrument will excel in reproducing these sounds.

Accompaniments – Rhythm Section

Another essential feature of portable keyboards is their ability to provide accompaniments to the melody being played. This function allows not only amateur musicians to quickly produce arrangements without the time, expense, and practice involved in traditional piano lessons but also aids beginners who are just starting to learn.

Recording – Audio Recording

While recording can be done through MIDI by connecting the keyboard to a computer, some models have this function integrated. This is the simplest way to capture what you’re playing on the keyboard during a single performance. It can be useful for solo practice, allowing the recording of the left hand and using it as accompaniment for the right (or vice versa) until the player is able to play with both hands together. In the case of using the MIDI function, you can even edit existing MIDI files with automatic accompaniment and your own performances, allowing the addition of vocals, for example, through the computer.

Screen

Up until now, we’ve covered the typical features of a keyboard, but there are various additional capabilities that vary from model to model and further expand the keyboard’s features. Modern keyboards often feature fairly large and readable LCD screens. Among other things, this helps with easier operation and more comfortable navigation through settings while playing without diverting your attention.
