Export drop out

When I export a project in X3, everything plays as it should except for the drums. They play intermittently. The drop offs have no pattern. If I try to re-export the project some parts that played the first try don't play the second try. Other projects seem to be working OK. Corrupt file perhaps? If so, is it fixable or do I need to reprogram the drum parts? Very frustrating.  Or something else?  Tom

I had this exactish problem not with drums but tiny flatlining of the entire mix for a sample time or two. One incident per song, while exporting this one song.
 
It turned out to be the MJUC Compressor on the bass bus.
I wasn't willing to mess with what I had going so in order to carry on with it, that song has to be slow exported - audibly cause I want to.

Sounds like a MIDI buffer too small issue. 

The reason I asked "which drum synth" is that if he was running BFD2 then there's a setting on the main screen labelled "offline" which should always be checked prior to exporting, then switched back off for editing etc.

Yeah this caught me out many times when trying to Export or freeze anything with BFD2 in it.
 
 

Thanks to all for your help. After freezing the synth, I was able to see that my drum parts were the problem. It seems I had a lot of overlapping drum parts that somehow created gaps in the export. Playback is fine in Sonar but didn't work as an export. As a result, I redid the drums and they now export properly. Newbie mistake no doubt. Now a new issue;
 
The mix sounds clean and crisp in Sonar but the export sounds a bit "dull" with seemingly different sound levels on the various tracks. Any tips on keeping the sound in Sonar the sound I hear, after export?  Again, thanks to all.  Tom

If you are exporting a 24 or 32 bit project down to 16 bit make sure you have the "Dithering" option enabled. There are also multiple settings for dithering with varying qualities. Usually the Pwr Dither options are best.
 
Also maybe you have some EQ/Compression on your Master bus. If you use the "Track" export option or choose a "Bus" export that ISN"T the master or the Mains then you lose the effects on the Master. Of course you also need the "FX" option checked off in the Export dialog.
 
Just some ideas.
 
@Jonesey... BFD3 does indeed look pretty wacky in the vids I've seen but likely worth the effort. Honestly I'd be more than fine even with BFD2 which I never got around to upgrading to but aside from old stock boxed sets I don't think that's an option anymore. IIRC BFD3 has a lot more routing and environment options. I stopped torturing myself by watching the promos though. lol

I'm not sure how FXpansion have managed to do this but......
 
All of my BFD2 stock kits can be played in BFD3
All of my purchased expansion packs will play in BFD2 & BFD3
The stock kits shipped with BFD3 will only play in BFD3
 

I think that's because when they sampled the new kits for BFD3 they took into account the new features they were adding and mic'd/sampled it all to create the extra dimensions. Like there's some extra code or something in there that only the new engine can retreive so they not backwards compatible.
 
I could of course be talking out my butt though because I base that on promo videos I watched ages ago and am extrapolating the situation on that info and what you're saying here.
 
Also totally threadjacking. lulz...
 
Sorry to the OP.

I believe it is as simple as:
BFD3 ships stock kits with samples in flac format
BFD2 does not play flac format

Good info and makes total sense. Cheers.
