nyquist - 3.20+ds-2 main

Unlike score languages that tend to deal only with events, or signal
processing languages that tend to deal only with signals and synthesis,
Nyquist handles both in a single integrated system. Nyquist is also flexible
and easy to use because it is based on an interactive Lisp interpreter
(XLISP).
.
With Nyquist, you can design instruments by combining functions (much as you
would using the orchestra languages of Music V, cmusic, or Csound). You can
call upon these instruments and generate a sound just by typing a simple
expression. You can combine simple expressions into complex ones to create a
whole composition.
