Re:Imported WAV audio tracks out of sync time wise

We found the problem - though there is no good solution now.
Because hardware Reverbs and other effects were being used via the Sends and Returns, they were not able to use Sonar's EXPORT feature to make a mix of the song (because obviously with no audio playing, there would be no signal going to the external hardware effects and returns).
They instead were recording the SONAR playback with another "2 Track Mixdown" application in the background.
Doing a side by side test recording between SONAR and this application tonight we found a timing variation amounting to a time stretch of 99.330% between the two software applications when the resulting files are over layered and analyzed.
Moral of the story ------ if you are in a studio that likes to use external hardware in your final mixing steps with live audio feeds, DO NOT record any mixdowns this way until you are working on the FINAL MIX.
For generating mixes to use as guide tracks for distant singers or other musicians, it is very wise to use only Sonar's EXPORT function and use plug-in effects for this "rough mix", so as to avoid these kinds of random rate conversion or other variances between multiple software applications.
