 The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs.  Some people simply choose the classes they need for a particular project and copy those to their project directory.  Others like to compile and link to a library of object files.  STK was not designed with one particular style of use in mind.

 It appears that socket support in Tcl/Tk on OS X uses the Nagle algorithm, which produces poor response between changes made in the Tcl/Tk script and the resulting audio updates.  Note that this is only a problem when using a socket connection from a Tcl/Tk script.
