Thanks for reading!
 
I've been having a problem mixing down (exporting) a project in X2 PE. 
The resulting file consistently only contains one track (used to be dry drum track, now dry keyboard track)
I'm selecting "Entire Mix" iand de-selecting "Fast Bounce" in the export dialog box
I've tried uninstalling both the ASIO drivers and Sonar X2 PE.
Also bounced and froze everything.
Tracks and busses meter during export.
After export, the project only plays the track that mixed down, and I have to close it without saving and re-open it to get it to play normally. 
 
Playback is normal and without dropout.
 
Any clues for the clueless?  Thanks for reading!
 

Make sure all the tracks you want to bounce are selected. I usually do Ctrl+A before mixing or exporting.

yup, CTRL-A is your friend during mixdowns.

Need proof? The cat in Guitarmech111's avatar hit Ctrl-A prior to mixdown. I rest my case.

Craig, Guitarmech 111, 
 
Thanks for your replies.  I had not been selecting all tracks prior to export, as I thought that selecting "Entire Mix"
in the export dialog accomplished the same thing. 
 
I tried your suggestion and was confident I had done so correctly, as all tracks ( not busses) were highlighted in blue.  My mixdown result was the same as before....containing only a stereo piano track. 
 
Do busses also have to be selected, and if so how do I do that ( I'm not new to Sonar...just want to make sure I'm doing it correctly) ?
 
Thanks in advance for your helpful replies.

Chris, list your steps to the mixdown. Are you bouncing to tracks first? That is what I do so I can see what the mix is like before exporting.
 
This is my process before exporting -
1. CTRL-A this selects all tracks in the project. Make sure you do not have tracks muted that you want to mixdown.
2. Bounce to track(s) - I choose a single mixdown track and not the separate buses.
 
If the mix sounds good, then I export the audio.

I make sure to go to "Select None" then choose "Bounce to Track". I then select "Entire Mix" and make sure that all Fx, Sends, Busses, and all that is checked. I also use "Fast Bounce" on the first few times to make sure I got it the way I want.

Conley and Grem,
 
Thanks for the quick replies...I'm using CTRL+A to select all tracks, then choosing File, Export.
Then I'm choosing entire mix from the drop-down, 44.1 K, 16 bit , choosing location for file and name, de-selecting
"fast bounce" (suggested by Cakewalk Tech) the Export. 
 
Wav tracks with efx have been bounced to tracks.  Midi tracks going through soft synths are frozen.  I have 5 or 6
busses to consolidate efx.  Those busses are NOT highlighted in blue in the upper left hand corner like the individual tracks.  I want to make sure I'm getting the mix through the busses as the efx in them are essential to the overall sound. 
 
Should I bounce all midi tracks to their own respective audio track instead of freezing the synth(s) they run through?

This is one of those issues where if I was looking over your shoulder I could probably solve it in 30 seconds...something isn't right. 
 
Are you still getting only a single track even when you choose Ctrl-A?

Craig,
 
I wish you were standing over my shoulder...come on down to FL...I've got a room in the back.
You're right...something is not right, and I think it's project specific.
 
Yes, I tried it with CTRL+A and all tracks were highlighted in blue behind the track #. Got the same result as before, a stereo keys track.
 
I'm going to try to bounce all to a stereo track within the project. 
 
I'll let you know what happens.
