tempo change problem

[soloproject]

has anyone else had a problem with recordings slowing down or dragging after export?  i recorded some auxiliary percussion while listening to the drum track playing through headphones from my computer.  when i converted the track to a wav file and imported it into my project, it didn't sync up to the track i played along to.  by the end, it was a full measure behind.  i tried the whole process again with the same result.  i'm just wondering if i'm doing something wrong when i'm exporting, or if the problem might be with the software i'm using.

So you're doing your main project on the computer and your trying to get the percussion you recorded with the micro br to sync up with it? I just want to make sure if I'm seeing this right....Should work fine~ What software are you using? I've never had this problem...

first i recorded the drums using the line input.  i exported that and imported it into sonar.  after the fact, i decided i wanted to add tambourine, so i played back the drums from my computer, through headphones, and recorded myself playing along.  i exported that from the br, imported it into my sonar project, and when i thought i had the two tracks lined up, they didn't sync.  hopefully my tambourine skills aren't that bad.

  I'm sure you can play a mean tambourine!  Hey, I've done this before with different guitar and vocal tracks..They always lined up for me. I take it you don't have the origianally recorded drums in the MBR anymore? You could've just recorded the tambourine with that~ bounce the tracks together and export the whole thing back into Sonar.....

Oh wait~ you can play back your drum track that's in Sonar through the MBR by hooking the Speaker out on your PC to the line in on the MBR~ and just record it back onto it~ then lay down your tambourine~ bounce to 2 tracks~ export....You'd have to redo your tambourine 1 more time, but it would work!!

Could it be that your project in Sonar is 48kHz and the BR is 44 ?

Just a thought.

You should have listened to the drums on the BR rather than the computer while adding the tambourine. Then the two tracks would have synced up perfectly and you could export the tambourine track. The exported tambourine track could then be imported into SONAR where it would sync perfectly with the previously-imported drum track.

The drift is caused by latency in the computer's playback. If you monitor the first track from the BR while recording the second, there's no latency because the computer's not involved.
