Right, but does SONAR actually import a tempo map, per se? I thought I'd read somewhere that SONAR doesn't import/read a tempo map and that the workaround was to import a MIDI file containing tempo information. I'm at work right now so I don't have SONAR/Melodyne accessible until, oh 7.5 hours from now. :(

I had some difficulty getting this to work as I wanted it to, which I was able to solve by setting the Audio tracks to Absolute time in the Inspector. I had clips starting at different times in the projects and they slid around when the new Tempo Map was applied, as long as they were in M:B:T basis instead of Absolute.
 
Anyway, since I might have appeared to be complaining then, I'll be sure to chime in now to say that this feature is fantastic.
