Right. I understand what harmonics are. I'd expect timbre to get weird from aliasing of the high harmonics, but since all the partials within an octave above that C5 are under the Nyquist frequency of a 2048Hz sample rate, I'm a little surprised that the pitch is affected. I guess there's probably some destructive interference being caused by the aliasing though. Maybe that's what's ruining the tuning.
