Hi'y'all!  So here's a problem that I can work around, but it is slowing me down - I have Sonar X3e build 352 on two different PCs.
Yet when i move a project from one PC to the other some of my Virtual instrument plugins get their input sources mixed up with other virtual instrument sources.  I am able to go in and locate errors and re-assign the input sources, but it takes some time every time i switch PCs - note that these are not switches to hardware routing, but switches to software routing entirely within Sonar. 
 
Is there a reason things are this way that i don't know about, or is it a bug of some kind?  Is there a way to sort this out, so i'm not wasting time or guessing about the state of a project when i open it?  One of my PCs is two years old, the other one year, and a bit faster - better caching, but both Intel i7 win7.  TIA.
 

We switch projects between PCs - but only with plugins.
Therefor all plugins must be installed and configured at the exact same way. For example no mismatch between vst2 and vst3 or different installpaths.
Take a look at this instruments if they are really installed in the same way and vst-version.
Make a test with only 1 or 2 instruments in an empty project and review what happens.

...or different installpaths...

 
Filepaths are irrelevant. I run Sonar on 3 separate computers with dissmilar configurations, different numbers of drives and different filepaths for installations, multisamples, VSTs and DLLs. Projects get transferred between them on a weekly basis without any issues.

Great! So may i assume from this that i am dealing with a bug of some sort?
 

Are you talking about midi controller assignments being changed on you?
 
If so, I am wondering if it is due to Windows on each computer assigning a different order to the USB devices that are plugged in.
 
The way I understand it, if I were to plug my midi controllers on a single computer, into different ports than they were plugged into when I recorded midi tracks for a given project, that Sonar would jumble up which midi tracks had which midi input device specified, and that this is due to the way Windows identifies USB devices.  I think it is done by numbering or some combination of name and number, so that when the numbering/assigning of detected USB devices changes (by my plugging things into different USB ports), Sonar has no way of keeping the midi input assignments the way they were set initially.
 
IF the above is anywhere near correct, then it might be that the order of ports the devices are plugged in on the second computer would then cause a similar jumbling of the midi input assignments for the midi tracks in Sonar.
 
Could the above be possible?

I think it's the VSTi channels in Sonar that get crossed.  For example, if i have a Tyrell VSTi and a DimPro VSTi in a project, it may not play one or both, and when you click on the 'Sonar VSTi Channel' that should open the Tyrell GUI, it may open DimPro instead, even though the 'Sonar VSTi Channel' looks the same until you look in the output assignment of the 'Sonar VSTi Channel' and find that the 'output' is no longer assigned to the right VSTi.  I think the input may not even be affected.
 

Take a look at the items in the drop-down menu for the output of any midi track in the project. Do you see the same sequential list of available softsynth outputs in both setups? Or there is an extra item at the start in one of the setups?
