SISD machines

SISD machines call for the concept of sequential programming in which a program consists of a list of instructions to be executed one after the other. Although such machines may now work so fast that they appear to be executing more than one instruction at a time, the sequential programming paradigm still remains for most techniques and tools for software development, including sound synthesis. 

As far as sound synthesis is concerned, parallel supercomputing is commonly associated with the possibility of breaking the speed limits imposed by SISD machines. However much faster sequential computers become, parallel computing will still offer interesting programming paradigms for the development of new synthesis techniques. From a composer s perspective, it is this latter aspect of parallel computing that excites interest.
