Logic Pro 9 Lagging drums

I'm not much of a drummer so I usually play a few bars on my Roland kit then cut out a few bars an create a loop out of them, the I quantize them to get the meter good and tight. Today, I cut a 4 minute song repeating the same 4 bar loop. Funny thing, during playback the drums seemed to gradually get ever so slightly behind the beat but really tight with the click track.

Is this latency or should I retrace my steps maybe I screwed something up inthe recording/looping/quantizing phase?

How can it get behind the beat _and_ be tight with the click, both at the same time? How is your click track generated?

My gut instinct here is to suggest that perhaps the four bar drum loop was not trimmed exactly to the downbeat of the bar. That would account for it gradually getting out of time a little bit more with each iteration. But I can't explain how it can still be tight with the click at the same time, at least not if you are using the internal Logic generated click as your click track.

Thanks, kinda what I was thinking also

Does seem odd that it would keep up the factory click yet sound laggy. Your trim suggestion is good, can't find any evidence that but I guess I will try to dig deeper.


Thanks.

Open an Event List. Go "up" one level using the arrow button at the upper left. And check the region start and end time. You can optionally view the length of the region in absolute time from under the view menu.

This happens to me only if I don't pay attention and wind up looping a region that's not exactly trimmed to the measure as Eli stated. I'll bet $50 on the wonky region theory....
