True to a point but the OP has yet to get back with us and explain it a bit more. Also I am not sure that what you are saying is accurate about wave files. Then it could be that Sonar is unable to make a determination but that should be a different issue that I have never seen. If you have and you have found that right clicking is an answer by giving a tempo how can you be sure its the right tempo?
Well John, I get samples from all over and many of them are just sound EFX so when Sonar looks at the audio it cannot find a bpm to fit it in a set space for the clip length, that's when you get the "busy" and cannot play the audio. If the clip is a standard acid loop, it will have that data inside it and Sonar will read it and will display it correctly the first time. However most of the time I have to do the right click thing to tell Sonar a tempo, even if the audio doesn't really have a tempo, to get Sonar to set the length of the clip display.
I don't know, but it seems Sonar is the only Daw that has this issue? Can someone confirm this?
