Electronic keyboard (Synthesizer)

An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a rompler-based synthesizer with a low-wattage power amplifier and small loudspeakers. Electronic keyboards offer a diverse selection of instrument sounds (piano, organ, violin, etc.) along with synthesizer tones. Designed primarily for beginners and home users, they generally feature unweighted keys. While budget models lack velocity sensitivity, mid-range options and above often include it. These keyboards have limited sound editing options, focusing on preset sounds. Casio and Yamaha are major manufacturers in this market, known for popularizing the concept since the 1980s.
