Chapter 11


The availability of the microprocessor in 1971
ushered in a paradigm shift from large,
mainframe computer music systems to the
personal computer.



One of the first “oscillators on a chip” used by
musicians was the inexpensive and widely
available Signetics NE/SE566, designed for
use in touch
-
tone telephones.

A breakthrough in microcomputers came with the
arrival of the KIM
-
1, a predecessor of the Apple
computer that used the same chip set. Composers
began to adopt the KIM
-
1 for musical applications
during the early 1970s.



By the early 1980s, the affordability of integrated
circuits and microprocessors was directing
development toward the production of sophisticated,
multifunction sound chips and digital signal
processing components for electronic music.

The availability of MIDI in 1984 incentivized
microcomputer makers to develop more
robust methods of producing computer music.




One result of this activity was the sound
card, or expansion card, which could be
added to a personal computer to expand its
synthesizing capabilities and provide analog
audio output of the sound signal.

Software instruments and digital audio
workstation programs provide software tools
for the electronic music composer on a
microcomputer.



There is a tradition of instrument
-
making in
the field of electronic music involving
composers who construct electronic musical
instruments from inexpensive components for
the purpose of realizing works for media or
live performance.
