I've never had an oscillator capable of through zero FM, so I can't
comment on how it sounds. If I remember this correctly (brain isn't
as young as it used to be), the oscillator waveform changes direction
as the FM signal drives the frequency below zero Hz. With most
oscillators, the waveform will just continue in the same direction.
