I was trying to record a vocal today on a bare un-effected track but as soon as the record arm button was clicked I was getting delay from a completely different track on a completely different buss. No effects assigned to either the vocal track or the vocal buss OR THE MASTER buss. I even inserted a brand new audio track and re-set all the proper routing up. Same thing on it too. Only way to record the vocal was to mute all fx in the project. Your thoughts?

Hidden bus in track manager?

Nope...but good guess Craig.

Not much info to go on. When you say delay, do you mean like a single echo? Or with feedback? Can you hear the dry vocal, or only with echo? Are you using plug-ins with a look-ahead?
 
Click the PDC button then click it again, and report back. Also, check for poltergeists.

Nope, it's from a guitar track using Echo Boy...which is on it's own "guitar track" and bussed to the Guitar Buss. This I found out by painstakingly turning off effects until I found the offending culprit. Why it's feeding any and every vocal track, all of which are bussed to the Vocal Buss is a mystery.

Check and double check the 'Echo boy' effect and see if there are any routing possibilities that will enable it to make it self seen by the other tracks. Also, Double and triple check your Entire signal chain.

Think of it this way. If you wanted this routing and did a post asking how you could create this routing in Sonar, you would get a bunch of replies saying it's impossible - DAWs just aren't wired that way. Maybe it's the mixer apple that comes with your interface doing some routing on its own? Sidechaining something by accident?
 
If you can't find the anomaly, I'd suggest is starting a new project, re-creating the existing setup, and testing it with a loop piece of audio or whatever until the problem happens so you find out what was added to create the problem.

I did create a new project and have no such anomaly in it.  Echo Boy has no such routing going on.  This certainly isn't the first or only time that "crazy" stuff has just cropped up in Sonar.  And, I'm sure, it won't be the last.  The offending FX aren't "going to tape" so once I did record a vocal track it was fine.  But If I arm any audio track that is routed to the vocal buss it gets the Echo Boy treatment.  Go figure.

Something similar happened to me yesterday...
I had a send on two of my gtr tracks going to a bus with an ambience verb.
I turned off the sends to the bus but I was still getting an ambience verb with my guitar.
Turns out that somehow the sends got duplicated and I actually had two sends on each track feeding the bus (hard to tell how many sends you have going on in track view...)
Once I deleted send number 2, all was well again!
Don't know if I hit a hot key or something or how it happened but I now know to look for that...

Iv'e had very odd behaviour happen between tracks and busses,one of which is the before talked about phasiness,or polarity weirdness if using waves Kramer Tape on both a track and a buss simultaneously,which is now a big no no.
 
I just have the feeling that Sonar is packed to the gills with so much stuff,that sometimes odd things are just bound to happen,though I'm certainly only guessing on this.
