if you have alot of midi softsynths in your project they take time to load,its not always about audio tracks,its loading soft synths.
it can take up to a minute under heavey loads but not 6.
id call tech support or your just going to be guessing along with everyone else,including myself.

Yes, I use several VSTi (Kontakt, Stylus, Addictive Drums etc.), but still - Cubase AI6 with same instruments starts thhee times as fast... I tried everything suggested - no effect. Disk IO doesn't looks like it - Cubase does not have any problems, projects are on the same drive. Disks are checked for errors and defragmented...

Easy way to find out if it's your sample libraries that are causing the long load time: freeze all of your sampled instruments, save the project, close SONAR and re-open the project. Most of the time, the difference will be dramatic. It's not about having Kontakt in your project per se, but rather what libraries it's having to load.

Given the extreme load times you're experiencing, though, the plugin-scan theory is the more likely explanation. There is really no reason to do the scan on every startup. It's only enabled by default to simplify new installations for new users.

Do you have audio snap enabled or/and V-vocal clips? THere is something that needs rendering in that sonar project that is different from the Cubase. Cubase doesn't have audio snap and a sonar project and cubase project will not be identical. because they have different features, like Audio snap and many others.
 
Also, do you have VST Scan Upon Start Up enabled? You do not need that, disable it at once and try again

You'll figure it out,

I seem to remember one of the Cake staff saying it's worth leaving the scan on start up on all the time, as it takes very little time nowadays, and makes life easier.

Maybe so. And if un-checking the scan on start up makes the OP's startup faster, maybe the question should be "why does scanning on startup on my machine take so much longer than it should?" If it does not then he can rule out that as the cause of his problem.

The OP is talking about loading projects which surely makes scanning for vst's irrelevant in this case? He's not talking about opening sonar.


I would have said open the projects in safe mode and load each vsti one at a time to see if any are particularly slow.

How about adding your vst directories to the "exclude" list of your antivirus software? I don't know if it's the same with Sonar, but with Pro Tools I remember things would take an age to load until I did this. 

Having said that, I noticed significantly longer project loading times when I upgraded to X2 from X1.

Your VST scan will never scan your antiviral software unless you go into it and tell it to.. It only scans the VST folder as default. It doesn't scan you whole PC

Sorry CJ but talk about missing the point 


Sharke was talking about anti virus software scanning the vst folder, NOT the other way round.

If you run Kontakt or other NI synths projects will load slower because they need to load their samples into memory. VSTis take a little time to fully load. VSTs shouldn't take much time.

There in no need to stop VST scan on startup now. CW did a lot to make it instant if there is no change. If you have added a VST it will only scan that one. 

Well, I've tried everything - no luck. I can definitely say that it's VST instruments - if I remove all of them, project loads very fast. If 5 instruments that I have are in the project - it takes 6 minutes to load (yes, I timed it). The worst offender is Addictive Drums, but even with it removed, it's still takes 3 minutes to load a project. There is no way it's normal - Cubase loads same project (recreated with all tracks and same VST instruments) in maybe 20 seconds or so on the same PC. I've tried all audio optimizations and scanning is turned off, my antivirus is off too. I don't know what to try next... I must not be the only one with this problem. I found some mentions of similar problem (that's how I checked AD - it was mentioned to cause hangups in Sonar), but no solutions... What's interesting, once the project is loaded, even if I completely close Sonar and then open it again, same project loads very fast - in about 18 seconds!!! I can't explain it. There must be something that does it the first time... Maybe some system process that's started or something else...
