MIDI + Audio keyboards
The keyboard refers to a keyboard instrument in which sounds are produced electromechanically, electronically or digitally. This product type includes electric pianos, synthesizers and small, very portable keyboards. What they all have in common is that they are significantly lighter and more compact than a piano. An important main distinguishing feature is also the number of keys. By far not all keyboards have the full 88 keys of a conventional piano.
On the other hand, keyboards offer many possibilities for effects and sound modulation in addition to playing tones. Especially for the production of electronic music they have become indispensable.
