A programming language designed specifically for constructing soft synths, and the software that implements it.Evolved from the groundbreaking MUSIC I-V programs developed at Bell Labs in the 1960s, the package is currently available through MIT Press. Csound contains built-in algorithms for generating and modifying signals in various ways, and it allows the programmer to implement arbitrary algorithms to manipulate digital signals down to the individual word level.An extremely powerful package, but academically oriented and not really commercially marketed (MIT Press charges just enough to cover its costs), Csound has only minimal user interfaces and requires some dedication to learn well enough to be usable.
