Phase flip question

[jono grant]

Hi there, if I have my drum "bus" being sent to an aux track, let's say with all effects disabled in cakewalk, when I flip the phase on the aux, it should go null, disappear. Why do I still hear bits of audio?

Considering the plugins are disabled, why would the aux send not be aligned perfectly with the source? Sorry if I'm missing something simple. I've tried with low buffer size and high buffer size, same thing.

(Update, just tried this with a new file and only one stereo track and it did go null. So then, why would a session with several tracks not do the same? Again, plugins are bypassed)

(Update 2: If I delete the aux track and create it again (send from drum bus) it goes closer to null but I still hear a little bit of audio after flipping the phase. So, that's also inconsistent behavior. Why would it be any different to simply remove and put a new aux track??)

 

Thanks!

All it takes is for the levels to be slightly out (i.e. one slightly louder than the other) for it not to null completely.
