Charles Babbage’s mechanical ‘Analytical Engine’, designed in 1833, is regarded as one of the first computing devices. A century later, using electro-magnetic and vacuum tube technology, the massive, iconic, electronic computing machines appeared, easily filling a large hall. After the invention of the transistor, with innovative companies starting to combine them into large scale integrated circuits in the late 1970s, the ‘micro computer’ took off. With Apple and IBM as innovators, these drastically changed the world we live in. In their slipstream, musical instrument and professional audio manufacturers followed by including microprocessors to produce ‘digital audio’ products, eventually rendering most analogue technology obsolete. The big market transition of analogue mixing consoles to digital ones happened at the turn of the century.
