tracks don't play in sync - Sonar 4

[musicbiz25]

Sometimes Sonar 4 starts playing the tracks out of sync. I can be working for an hour in a file and everything is fine. Then suddenly the tracks will play out of sync. It happens when there are as few as 5 tracks in my file or 40. And if I just solo the tracks I here out of sync, it plays in time.

Does anyone know what the cause is? Is it a latency issue? My soundcard is an audiophile 2496. I have 1 GB of RAM and a 3.4 GHZ Intel Pentium processor.

Thanks for any help.

Sorry I didn't respond sooner. I overlooked this thread.

Well your computer seams powerful enough. Of course, if it's being used for internet, has virus scanner on it, and about zillion programs, it may as well be a Pentium 3 450Mhz. If you are using it as your main computer too, you may consider setting up a dual boot system. If you are not sure about this one, just ask.

And if I just solo the tracks I here out of sync, it plays in time.

I'm a little confused by this statement, could you clarify it a little bit please.

I'm assuming that you aren't physically bumping the tracks by accident.

Do the tracks stay equally out of sync or do they continue drift further and further out of sync?

Which tracks go out of sync? More than likely, if you can figure that one out, you'll probably figure out what's going on.

You don't have any time stretching or pitch shifting do you?


I must admit that I know little about Sonar as I've never used it. However, I've dealt with this sort of crap enough in Vegas and Cubase that I can surely help.

I have been having very similar issues. Not too many tracks, but when playing a track that involves a truepianos softsynth, this track continues to drift further and further out of sync....

When i route to regular GM synth on soundcard, it works peachy keen

I am assuming this is a latency issue. I am using the asio4all driver. I tried the other drivers (WDM & MME), and they both caused strange things to happen - i.e. not showing up in INPUT /OUTPUT drivers list in AUDIO OPTIONS.

I tried to get into MIDI about 10 years ago but had too many frustrations (crashing, lagging etc.) I thought that with my newer and pretty beefy computer, things would work better now. But alas... no such luck
