I started a new song which consists of, (at present), a series of audio tracks that are 'multi-take lane' tracks.  On Saturday I brought in all the audio and when I went to shut down I got a "Building Transient List" message and it took quite a while for Sonar to actually shut down.  Last night I worked on the song again, comping together the finished audio and again, when shutting down I got the same message, "Building Transient List".  After about 45 minutes I 'ctrl-alt-del' to get out of Sonar.
 
Can anyone tell me what's going on here?  I have no Audio Snap being used in the project.  After I got Sonar shut down last night I opened the project again and went through each track just to see if I had inadvertently engaged Audio Snap in one of the lane filters.  Nope!  This time, however, it shut down clean.
 
Any thoughts would be greatly appreciated.
 
TIA

Building the transient list for each audio file should happen at the time of import/recording. This is what allows you to tab to transients even when the edit filter is not - and has never been - set to Transients.
 
If that hasn't already happened before the first save, I think something must have have interfered with the process. If a clip is showing 'Busy' after import, you might need to zoom out a little; for some reason the generation of picture files and transient lists doesn't complete when you're zoomed in too far.
 
But that still wouldn't explain how long its taking to do it on save/close if you haven't used Audiosnap 'Split Beats' on drum tracks or something like that.

I have been attempting to get help since December on this issue. Happens for me upon project closure both in busy projects and in new projects. See below for my threads and a problem report.

Been two months since my problem report so I'm not holding my breath. Can only assume this issue is so infrequently reported that its sitting at the bottom of the priority totem pole. Hrmph.

Thanks Dave.  All the audio clips imported without a hitch, no 'busy' message.

I knew I'd seen this mentioned before.  I guess we'll see what happens.
Thanks.

I do not know what causes this, but I have seen it before, and what worked for me to stop it from happening was to bounce all clips to themselves, then save the project.

The mind-boggling thing on my end is that it happens when I stream a file via Browser even when it is not imported into the project anywhere! This is on a blank project. Double hrmph.

I worked on that same project again last night and it closed several times with out a hitch.  Go figure.....
 
Thanks to everyone for you input.
