Tempo speeds up when exporting audio

I'm running SONAR Platinum (fully updated).  I haven't exported audio in a few months, however today when I export, the tempo in the output file progressively speeds up as the song progresses.   The project has a constant 120 bpm tempo.  Doesn't matter if the export format is WAV or MP3.  The songs plays fine while inside of SONAR.  Besides Cakewalk-supplied plugins, I'm using Melodyne Editor 4.1.1 (latest) on one vocal track.
 
Anyone have any ideas what is wrong?
 
Thanks,
Steve

    I solved my own problem.  Wasn't as SONAR problem after all.  Somehow, my MOTO 828X audio interface got confused and was playing everything fast.  Cant'explain it, but problem solved.

    Usually this happens when one application has the interface's sample rate locked to a value that differs from the wave you are playing back. So a 44.1 wave played back with the interface locked at 48 would sound fast.

    I make some videos. This one shows how to do a physical loopback on the RME UCX to get many more equalizer nodes.

    I concur with the above post, from gswitz, on it likely being that the interface and the project were set to different sample rates.
