ABSTRACT:
A method and apparatus for providing multiple clients simultaneous access to a sound input/output (I/O) data stream. The present invention provides a method and apparatus for providing multiple programming data structures and multiple patch points in a list, in which each of the patch points are positioned relative to at least one of the programming data structures and is capable of receiving at least one programming data structure for insertion into the list to perform a function. The present invention also includes a method and apparatus for providing at least one buffer for inputting the data stream into and/or receiving the data stream output from each of inserted programming structures, such that each inserted structure can access and operate on the data stream. In this way, multiple clients can access and process the data stream transparently, without interfering with the operation of other clients, yet affecting the sound stream in the desired way.
