Hi all,
I have troubles exporting "mixdown" of my tracks. The project consists of both, audio and MIDI. Audio tracks render just fine, but MIDI tracks are about 8th "quicker". By that I mean I have to move them 8th note forward to sync with audio tracks. I have found this by exporting not a mixdown, but individual tracks, imported those into a separate project and there I could see it. However, that is not all, also the automation on audio tracks is "screwed up", it just doesn't sound the same after mixdown/export as when played in the original project file. I suspect I have some wrong settings somewhere in the jungle of Sonar's settings for exporting or latency compensation etc. 
 
So to break it down...
 
1. The original project, played as it is plays perfectly fine
2. When exported into mixed wav, MIDI is moved in time and the automation is skewd
 
Details of what I am using and am aware of...Windows 7 Ultimate 64 bit, Sonar X1d (build534) in 64bit version. Audio card - NI Komplete Audio 6 in ASIO mode. Audio card buffer set to 128 samples, output latency says 7ms, input latency 5ms, total roundtrip 12ms/557 samples. Project uses 44100 sampling rate and 24 bit depth. Not using 64 bit double precision engine as default, but tried using it on export settings, didn't make a difference. Also tried to use "record latency adjustment" setting using the reported latency 557 samples. Didn't make a difference.
 
I am running out of ideas here. I cannot export the project to show and play it outside of Sonar. Oh, and I tried to bounce the MIDI track into a new audio track and mute the MIDI track afterwards and mixdown with just audio. Still the same issue. Strange.
 
I can move the MIDI parts manually, but the skewd automation is silly.

So if you bounce a synth track to an audio track, the live MIDI-driven track plays out of sync with the bounced one? The only thing I know of that does that is a Bitbridge bug that adds an empty buffer of audio to the rendered audio, but you wouldn't see that much of an error with the buffer at 128 samples.
 
If real-time Playback is solid, a workaround might be to disable Fast Bounce, and export in real time. There have been issues with MIDI automation sync related to having count-in enabled, but I don't know of anything offhand involving audio automation sync or MIDI/audio sync on export. If fast bounce is enabled, export is an offline process that doesn't involve your audio interface or driver, so none of that should matter.

Not really...when I bounce to another track in the same project it plays correctly along the MIDI track, only when I export (you could say bounce to wav, I guess) the synth track audio  (in my case linked midi track and audio output from a synth) into a mixed wav (which later I would convert into MP3). Then in the mixed wav I can hear the track is moved...out of sync...and modulation of one of the audio tracks sounds different when compared to realtime playback in Sonar.
 
Yes, exactly, it should be offline without latency issues from the audio card etc. I have fast bounce checked. I think I tried to do the audible bouncing too, but had issues with it too, but I will double check that right away. 
 
I also thought it might be because this project was started and at one point I needed to reinstall Windows (I know, silly) and after that this project had troubles loading Battery and Kontakt at the point of opening and I had to select the proper path to samples etc. So I just finished a new project where I mirrored all the settings and tracks and everything from the original, but with a freshly opened Battery and Kontakt, so I have no issues in this regard anymore. But that didn't have any influence on export, of course. But I tried.
 
BTW, thank you so much for replying so fast.

So I tried the audible version of the bouncing and to sync problem is there too. Even if I freeze the tracks first. Even if I bounce them to another track. They play fine realtime, but when downmixing, it sounds offset. Just to be able to show the to someone I had to use a screengrabbing program, record a video of the track playing in Sonar and send the mp4 video to them...in less than ****ty quality. It is almost funny :)

If you can bounce/freeze tracks, and they're still in sync with audio, then I can't imagine how or why SONAR would continue to differentiate between those tracks and recorded audio tracks, and mix them out of sync on export, unless maybe they're going through separate buses on the way to Master, and whole buses are getting out of sync due to PDC issues or something. But if there's really something going on with export that doesn't affect bouncing, try bouncing everything to a "Master Bounce" track and exporting that.
 
 
 
 

There is a difference between bouncing and freezing a track. When I freeze a track it is still in sync, when I bounce it, Sonar do his "processing audio data" thing and it is out of sync, even in the track view. What I found out is something even stranger to me. I was wrong when considering the sound. It is not the MIDI track that is "faster", it is the audio tracks that are behind the MIDI. I noticed this when I bounced the tracks into new tracks in track view, I could see the snare on the second beat that WAS originally in both MIDI and audio tracks ON the second beat, is suddenly moved a little. See the linked picture.

Reading your specs I'm not sure I see a audio interface unless it's the Native Instrument device. 
 
I had this exact issue years ago when trying to use a Creative Sound Blaster audio card. So to me the answer is in your audio drivers. 

Is there any Audiosnap stretching applied to those tracks? Bouncing with an Offline algorithm that's different from the online (Groove Clip) algorithm could account for that. Otherwise... that's pretty strange. Any FX on that Break track? Do other projects do this? I'm guessing this is something project-specific.
 
Regarding JohnnyV's comment, as mentioned previously, bounce/freeze/export are offline processes that don't involve soundcard drivers unless you do a non-fast bounce so I really don't think that's anything to be concerned about.

Yes, Native Instruments Komplete Audio 6 is my soundcard. I used to have ESI Audio DuaFire which I have troubles all the time regard to their drivers. That was one thing I bought Komplete AUdio 6, to get rid of ESI thing. I hope it is not drivers. At least I didn't have this trouble since I bought it. I worked on one project before this and had no trouble with exporting in that one.

Regarding AudioSnap, I wasn't using it, as far as I remember. However, I since my project tempo is 100 and audio loops are not 100, I thing Sonar adjust that tempo to the project's tempo automatically. That could cause troubles, I guess. Would it help if I convert the loops into groove clips? Would that be better for Sonar to sync that with his MIDI tracks?
 
The Break track - yes, there is EQ on it (Eareckon FR-EQUA87 specifically) and there is compressor on master (2,6:1 in Limiter mode to melt all together and limit the possible peaks....same company).
