Metronome

First, the metronome won't be recorded unless:
1: it's leaking from your speakers or headphones into an open mike
2. You have routed it via your interfaces soft mixer back to the track you are recording. 

Hey, Flatty! 
ok... find the metronome buss (on the rt, near/in the same group as the Master buss...) if you don't see it, press H which will bring up a track list you can click to hide/show tracks... make sure it's checked... save.
 
Now look at how the metronome buss is routed... if you can't see (console), go up to the top left (Modules) and make sure in/out is checked... now look at the bottom...the metronome track is probably routed to the Master or some buss going to the Master... change this so the Metronome is going directly to your soundcard, in your case your Presonus firebird thingy...
 
Also make sure some effect like a reverb didn't get put on the Metronome buss/track by mistake... 
 
That should take care of it... 
 
You should make sure your "normal" start setup is this way or you'll have to do it every time... also, any song templates.  If you built them with the wrong routing, they all need to be resaved after fixing them.

When recording with the built-in metronome how do you keep the clicks from recording with the track? I do not have the metronome engaged during playback, just recording. It's a fairly faint click, but enough to ruin the track.
 

 
Is it really being recorded? Have you checked that metronome bleed is indeed printed in the wav file (i.e. best checked by just opening the wav file directly with windows media player)
 
If so, this is really strange because a while back I wanted to do that on purpose (i.e. export metronome or a least print a metronome track to wav file) but Sonar applies all sort of measures to prevent this from happening, so you have to do quite a few things to get a metronome onto the wav file ...
 
It would help if you describe what you record using what setup (source, interfcae, routing).

Do your interface outputs connect to anything other than an amp or powered monitors? When you say "direct recording", do you mean electric guitar via D.I. box? I'm not a guitar guy, but I would guess that a sharp transient like a metronome click could get picked and recorded at a low level by sympathetic resonance at high monitoring levels.
 
Otherwise it has to be either the interface mixer is routing output back to input, or the interface has an isolation problem between its analog I/O circuits.
 
 

I don't set my metronome to a bus at all, I just set the out of the metronome to the 1/2 out on my Octa- Capture and I never hear it again in my recordings.  I don't record with my Speakers turned up either.
 
Another way it so set the Metronome is to the 3/4 out on your sound card and have the 3/4 out going to a head phone amp.  Now you can just listen to the metronome only through the headphones.  But leave the bus our of it, Just route it directly to an audio out only.  You can find very inexpensive head phone amps.
 
Oh 1 more thing, I set the metronome to only count in on 4 beats but I don't check off record or play,  I just need it to count me in.  I don't use it to keep time, that's what the drum track is for. 
 
I use the metronome to record drum track, then the drum track keeps my time after that.
 
I hope this helps.

I'll get to that PC today and try some of these suggestions. Looks like I'll be recording that track again any way.
 
Thanks for the tips so far, guys.

It has to be my firebox then! I've tried everything suggested and it still bleeds through. Now I have an excuse to use this old windup pendulum metronome I have.
 
Thanks again for all the info, guys. Greatly appreciated.

That's not good thet your interface has a crosstalk issue. I would test it and if so then get rid of it. If there is cross talk then every track you record will be contaminated with the playback. 
 
To test it, simpley record a new track with nothing plugged in but turn the input gain way up. Now listen to the new track. 

 I unplugged the guitar so nothing was plugged into the presonus. Did as you said, turned the gain all the way up, recorded a blank track and as soon as the drums start (ezdrummer2) you hear faint thuds on playback.
 
I also noticed it was very noisy. With nothing plugged in shouldn't there be silence?

As Cactus said if you have nothing connected to an input you should only be able to pass silence to the computer. It should only record the noise floor of the device. Noise alone could also mean issues on the playback side, but crosstalk implies the guts of that box are not isolated properly (definitely not good).

How old is that unit?
