My audio engineer wants me to merge files that were auto-separated during a recording.  Basically something like after 2 gigabytes, the audio splits so we have multiple tracks for each mic.  Anyway, he uses Pro-tools and I use Sonar X3.  If I load the audio and line it up and bounce it, will Sonar "color" the audio at all if I have no post processing nor plug ins or anything?  I can see that the volume I hear and the volume it bounces to are not the same, so I tend to have to adjust volume and such but my ideal would be to simply combine and export exactly like the source audio.  Any tips on what I need to do?  Thank you.

Sonar does not "color" the audiofiles.
We have made a test for 2 years. I imported an audiofile "x.wav" and exported this as "y.wav".
Both files (Import & Export) were bit-equal. Without any distinction. No changes.
Volume, pan and gain must be "0". No plugins.
 
We do "bounce to Clips" several times a day without any changes in sound and volume.
 
We digitize large volumes of tapes and vinyl for customers (Thousands of gigabytes). Therefore we know that Sonar does not make changes.

Ok, perfect thank you.
