The user-written control program is also in C, and is compiled
and linked to the function programs (or the entire Csound) by the
user. It is not essential to know the C language well to write this
program, since the function calls have a simple syntax, and are powerful
enough to do most of the complicated work. Additional power can come
from C later as the need arises.
