When I render wav files and import them into another program, the tempo is incorrect. Plays fine but the tempo

I import into either Cubase Le or my RC50. This is a minor problem with Cubase but I'd like to sync it to the click on the RC50 but cannot because adjusting the exported file tempo in this device affects playback. I suppose this only makes sense for those using looper devices.

Any suggestions for locking in the tempo with the wav file data?
