Logic Pro upside down regions?

Whenever you have a stereo signal?

I mean: a guitar with stereo effect pedals?

A stereo pair of mics for a drumkit? A piano? An acoustic guitar? Any acoustic intrument? A backing vocal group? A synth with stereo effects or even panned oscillators?

But not for: a dry single vocal, a (mono) mic (on a guitar amp, any amp, anything).

That happens when you record on a stereo track only to the right hand side (stereo audio with a single waveform shown are: up=left and down=right). You can clearly see this if you'd zoom in vertically until the waveform splits into two waveforms for L and R):

Howabout 2 mics on a guitar cab? would they be on two mono tracks or one stereo?

No rules. It completely depends on what you want with those two tracks. I would probably put them on one stereo track if I wanted to "keep" their subtle stereo spread, and on two mono if I wanted to apply radically different effects on both sides (you could turn each mono track into a stereo track if you used a stereo effect on both, for instance).

Hi

Can you add the screenshot?
