I did go to waves and the problem is in SONAR. I confirmed SONAR was the issue when setting the track to a mono interleave, I did not get the issues with a mono plug working in stereo and out of sync.

SONAR needs to be a little smarter IMO...
 
IF I have a mono clip AND mono plugin, you would think SONAR would process the track as a mono track, but it doesn't. I even had a mono input assigned to the track for recording. (enhancement to the bakers) SONAR SHOULD HAVE FIGURED THAT I WANTED A MONO TRACK...

This is intriguing. Mono clip, mono interleave, but processed as stereo. How did you discover that it was stereo? Did you freeze or bounce it and see a stereo waveform?

No, the track was default as stereo interleave in the template I originally used for the project. I set the track to record a mono track as input. The take was recorded and drawn as a mono file, not a one sided stereo wave. This led me to believe that I was working with a mono file, not a one sided stereo file. The pan was centered all this time. Playback even played it back in the center too. I inserted a mono plugin specifically created and used for mono tracks by Waves - the MONO version of the plug.
 
Bottom line is that changing the interleave to mono got me out of the issue, but SONAR confused the issue with the way the track is laid out.
 
I presumed it was a mono track since there was a mono wave form drawn. NOT a one sided stereo wave form. If the track was a stereo interleave, I would expect that the one sided wave file would have been recorded instead of a mono single wave.
 
I see this as a fix - SONAR can either draw a one sided wave form, or change the interleave to mono when it records a mono track, or at least query the user if they want to keep the recording as a one sided wave or change the track to mono. No real biggie, this is just part of a lot of things I have been running into these last couple days with some older projects. I think that X2 has some issues with older files...
 
I hope that makes things clearer, it was a error with the way the project was laid out, but it was disguised as to what was really wrong.

I am really NOT liking SONAR X2 right now.
 
I have a mono bass track recorded. I added the Bass Rider into the FX bin. SONAR changes the pan and puts a stereo effect on the track with the signal panned. When I turn off the plugin, the signal goes back to mono processing.
 
This also happens with the API-550 mono plug too. This is a one drawn wave track, not dual as you would find in a stereo track in case you were thinking of making sure it was mono. 
 
Thoughts?

Is this 32bit or 64bit?

Amen to that! And the polarity button, too. This is one of the reasons I'm still using 8.5. I'm hoping X3 will have a fully-customizable track header similar to the toolbar customization feature, so you can show/hide whatever you like."
 
The track header is customizable in X2. Just not in the same way.

John, what is your finding on your last post here?

I am happy to report that X3 is acting the way I want it to in this regard of mono vs. stereo based on the track input. This has made me more happy about X3. :)
 
If you choose a mono input for a track, the track interleave is auto set as mono. Same for stereo, where the interleave is set to stereo.
 
Nice... :)
