 Hi,

I've tried to implement the Gordon Smith Oscillator but it is behaving strangely. 
The amplitude seems to be exceedingly high. There is lots of distortion and sidebands. It is not producing a pure tone.

I attempted to simple scale the sample like so

pOutputBuffer[0] = f_yn * 0.5 ;

but this did not produce the result I expected.
Am I missing an important step? I implemented the code as shown in the book.

Old topic, but I just visited this when I got the oscillator blowing up like this at first...

My mistake was simply a typo in the variable names - it is easy to mistype and create positive feedback.

The GS Oscillator as it is in the book does output sine waves ranging -1/+1 perfectly!
