corrected the typeo's,
 Used sampleFrame instead of float* making the code cleaner.
 Set up a socket to change the samplerate where required.
 Stopped using malloc ( yeah that was bad practice on my part ).
 Now using lmms_Math.h and the predefined versions of F_PI and F_2PI,
 I didn't know data from the knobs etc. was not updated over the course of a buffer, so have moved outside the processing loop,
 made appropriate functions inline,
 used sinf.
 Multiplication has replaced division where possible,
 zeroing of the buffer has been removed, as redundant.
