i'm not sure how, since i don't see a compare option in the system object. do i need some extension?
even then as far as i know it'd be possible only in seconds, which is very inaccurate, when the loop is done in samples or at least miliseconds.
i think having the program do it natively would be the best anyway rather than implementing workarounds.
go new event -> system, scroll down -> compare
it may be in milliseconds (should be since everything else in the program is measured in milisenconds)
It's only 1 event feature, not that hard for people to implement (I think, could be wrong)
