[PD] buzz~

It seems to me that buzz~ isn't working according to it's description. 

I'm using a zip file with source files dated in January 2002, and am running 
Linux, using the external freshly compiled using the supplied makefile.

The problem I am having can be seen using the buzz~-help.pd patch. 
When I set the frequency to some non-zero value, set "a" to result in a "rich" 
spectrum (ie > 0), and set "H" to 1, I would expect to see a sinusoid at the 
fundamental frequency (since H==1). But there are already strong overtones 
with H==1. The problem is quite obvious audibly to the extent that I can 
clearly hear overtones with H==1;  it's not just some subtle floating point 
approximation error.

I haven't gone through the code to work through the math yet, but I suspect 
there might be a problem either in the code or the documentation, or that 
there is a more recent version available.

Anyway, I just thought I'd post this in case you (Frank), or anyone has a 
quick answer. If not I'll certainly investigate the code if I get the time to 
do it, and report back.
