Casio is the brand of Electronic keyboard, which HH Priya Nathji uses. Actually Casio Company was the first to promote Electronic keyboards on a large scale and they soon become popular all over the world. People actually started calling Electronic keyboards as Casio. The company name Casio become synonymous with the product. Besides Casio there were other companies also which make Electronic keyboards like Roland, Korg and Yamaha, but Casio was the company which popularized this product among the masses and professionals alike and for long, people associated Electronic keyboards only with Casio.
HH Priya Nathji received a Casio from HH Pran Nath he had sent from London. That Casio was in the nature of a toy meant for children, and the sounds of the rhythm on it were very weak. That was infect, a model of the Casiotone series. Casiotone refers to a series of home electronic keyboards released by Casio Computer Co. in the early 1980s.
Most Casiotone keyboards were small, with miniature keys designed for children's fingers, and were not intended for use by professional musicians; they usually contained a rhythm generator, with several user-selectable rhythm patterns. Their low cost and abundance made them fairly common fixtures in garage rock bands all over the world. Then in late 1980’s Sudhir Saxena gave one of the greatest gifts that he could have given to HH Priya Nathji. He gave Him a Casio Keyboard, which was a more professional model from Casio. HH Priya Nath refers to the instrument as “Sudhir kaa baajaa” in the days that follow, whenever he tells Shri Nathji about his recordings. HH Priya Nathji loved this instrument. He still plays and records songs and gazals on a Casio electronic key board.
Casio Electric Keyboards are made by Casio Computer Co., Ltd. is a multinational electronics manufacturing company headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, cameras, musical instruments and watches. It was founded in 1946, and in 1957 released the world's first entirely electric compact calculator. In 1980 Casio released the Casiotone 201, its first electronic keyboard. As a compact and attractively priced unit that could play sounds from various instruments, this new product drew acclaim from music lovers around the world. Casio subsequently developed numerous features that were only possible using digital instrument technology, including one-touch auto-accompaniment, memory capacity to record and playback songs, auto-play, a melody guide function that guides users through a song by lighting up the keys, and sampling technology for recording any sound for use as a sound source.
Casio Electronic keyboards typically use MIDI signals to send and receive data, a standard format now universally used across most digital electronic musical instruments. MIDI messages would be sent when a note is pressed on the keyboard, and would determine which note is pressed and for how long. The values calculated by these sensors are then converted into MIDI data which gives a velocity value for each note, which is usually directly proportional to amplitude of the note when played. Thus it produced very accurate tones.
