[chuck-users] Gen10 issue with odd harmonics

[mario buoninfante]

Hi,

I found out that Gen10 has an issue with dealing with odd harmonics (not 
fundamental).
It's easy to repro simply taking the example code and using the 
following coefficients instead:

g10.coefs( [0., 0., 0.5] ); - shows the issue
g10.coefs( [0., 0.5, 0.] ); - doesn't show the issue

Hooking ChucK up to a spectrum analyzer it's easy to see the difference.
In case there are odd harmonics, there are a lot of unwanted 
partials/sidebands, instead of having only the components specified in 
.coefs().

Gen9 doesn't seem to have this issue.


Cheers,

Mario
