Description:    Interface for stochastic granular synthesis using Cmix 

    StochGran is an interface to "sgran", a Cmix stochastic
granular synthesis instrument.  sgran generates events made of many
grains of sound.  The parameters grain rate, duration, location and
frequency can be given beginning, ending and variability values, so
the grains will change over the course of the event. The values are
generated by a probability function which allows one to "randomly"
output values between a low and high limits, and which hug a middle
value by a specified amount of tightness.
     At this point the additive synthesis version of sgran is implemented.
Versions synthesizing frequency modulated grains and sampled grains
with in-phase correlation are in progress.
     To compile "sgran", you must have cmix installed. After "sgran" is 
compiled, link it and cmix commands "sfcreate", "rescale" and "play" 
installed or linked into the directory you will designate in the interface 
as the cmix directory.  Compile StochGran, and run it.
     Check the man page for sgran if needed to find out how to set
parameters. When you have set the parameters on the main StochGran
window, write out  functions and then write score with the menu
items.  Then run the job.   When you see in the output window it has
finished (it says how many  grains were written), you can rescale the
float sound file.  After it says "done", the sound file can be played.
