Hey Magnus,

I'll suggest that the most typical cause of "coldness" in an
oscillator is an unnatural synchronization.

A classic example would the be Top Octave Generator chips that keep
the pitches in a synchronization with each other that you just don't
find in nature.  Or any divide-by-N situation for that matter.
