You don't need to change the channel of the track you're recording, you just need to ensure you only enable Input Echo on the track currently being recorded. You can either manage Input Echo manually (my preference) or you can enable Always Echo Current MIDI Track in preferences, and make sure the armed track is the focused track when recording.
 
The reason I don't like the Auto Echo is that you cant leave a track input set to None, because 'Always Echo' (a.k.a. Auto Echo) will automatically change the input to All Inputs - Omni when the track gets focus.

OK here is EXACTLY what I did...

1.  I have multiple simple instrument tracks with notes recorded on to them.  No wheel movements on any of them
2.  I decided i wanted a wheel movement on one track so I simply clicked the "W" for "write automation" and armed the track.  Then I simply moved the wheel while it was recording.  I see the wheel movement drawing ONLY in the one track I did the wheel movements on.
 
How that wheel movement on track 1 is effecting other tracks is beyond me.
 
According to your last statement, this sounds like default behavior?  Wheel movements will be captured on ALL tracks because of the MIDI-OMNI (all)?  How come the events dont SHOW these wheel movements on those tracks?

Sonar should be smart enough to keep the wheel movements contained to the track I recorded it on.

Adding a little pitch bend shouldn't be that hard.

How about this. . . did you insert the synth with the "Enable MIDI Output" checkbox enabled?  I don't know if that would do it, but if you have everything set to MIDI Omni then that output would technically be a MIDI input to all other tracks.  A quick way to tell is to see if the synth on Track #1 is shown as an input option for the other trakcs.  Just an idea.

You are running the most recent version of SONAR, yes? There have been some MIDI fixes of late.

Hi Anderton,
 
yes I am.  So I was able to resolve my issue this morning by changing the channel of the track with the wheel movements to Channel 2.  
 
I never have to change the channel, but for some reason this time i do.  Now the other synths aren't effected.
 
Strange.  Thank you everyone for trying to help me out!

I just read this so now my theory is, do you have your MIDI controller set as an ACT Control Surface?  If so, do you have the control data being sent back to the controller?  Maybe it sent the pitch bend data back to the controller and the controller is sending a pitch bend message then to all the other inputs?  Just another wild speculation.
