Drum Replacer - lag on bounce to clip

Anyone else encountered this?
 
Drum replacer seems to be on the nail when it's running live, but when I bounce the replacer track to a clip, there's a slight delay.
 
The top track is the original recorded kick drum, the bottom track is the bounced drum replacer kick. The lag is consistent throughout the track.
 

 
 

Have you tried real time rendering? Or even raising your ASIO  or WDM buffers a bit.

Maybe it is due to an effect latency on that track?

You haven't upgraded your interface firmware and drivers recently? I assume you've done the latency loop back test and got the manual offset sorted... I have no idea if it would make a difference BTW just saying..

micro-second range.

Microsecond... could it be a result of the sample bank? Like if you are using multi velocity samples maybe there is some slight timing variation between the samples at the various velocities?
 
I think a good test would be to load a single sample (as opposed to a bank) and see if the fluctuation still occurs.
 
Another question... are these delays enough to cause audible flamming between the original and the replacement sample(s)? If not, although not ideal, seems like a "close enough" scenario. Still worth investigating/reporting. DR is supposed to be ultra precise wo I'm sure the Bakers would like to ensure that is indeed the case.

No. I wouldn't have noticed it if I hadn't zoomed in really close to do something else.

I wouldn't worry about it too much then. In fact it may be operating as intended. Perhaps if it slid the samples in exactly how you are envisioning the result would be less desirable. It may look at the overall sample as opposed to the very start and then make a judgment call as to what will make the replacement occur in the most natural way.
 
Like a kick with a slow attack and release being replaced with a tighter one that has a fast attack and release gets centered so the meat of the kick lands where it needs to to stay on time. If it was nudge to the very start of the original hit it may sound too soon and not last as long.
 
Just a thought. I have no idea if that's how it actually works. That would be pretty impressive though.
 
Cheers.
 
Edit: I just realized that may not make sense since the bounce is not reflecting the original replacement processing. However neither does a lot of Online rendering stuff versus offline so maybe the render process does something extra to make it tighter. Really though you should probably just ignore my blathering. Just trying to understand.
