I have a project where I am groove clipping the midi for a drum track to keep a meter. I have stretched out the clip for more than twice the amount of time needed for the recording just so I can have extra room for jamming if needed.
 
When preparing to bounce the clips to a mixdown track, the bounced track is a lot longer than the actual audio recorded. I do a select all and slide all tracks down to the end of the last audio clip length position in the timeline. Bouncing the clips to track produces a final clip that ignores the groove clip reduction and bounces the clips to match the end of the original groove clip before resizing it.
 
1. create new project
2. insert 3 audio tracks
3. insert drum synth folder with midi track- I am using Superior Drummer 2
4. Find groove in SD2 and place in SD2 midi track
5. Groove clip the midi and stretch out to 40 measures
6. Arm and record all audio tracks for 10 measures
7. Select all tracks for bounce to track
8. click drag midi drum groove clip from measure 40 to end of audio at measure 10. I scooched the groove clip trim and went earlier and later than my desired measure but ended up at the end of the longest audio clip
9. After the drum midi groove clip is set to length(measure 10), bounce to a mix track
 
In my situation, the bounced track was the length of the original drum midi groove clip. In this recipe, it was 40 measures when I was only wanting 10.
 
Should I need to bounce the midi clip before bouncing to tracks? I never had to in the past.

In your timeline, is it shaded for 40 measures, or just 10?

the timeline is 40 measures shaded. I think it should have followed the trim action when all clips were selected.

You might be right, but if you hold down ctrl, then left click in the timeline where you want it to end, instead of dragging the clip, you should get the desired length.

I guess the question is why wouldn't the shading follow the trim and when all clips are selected?

I'm not sure. It's just the way I've always done it, and it always works, so I never tried the other way. :)

I can trim the timeline, as you suggested to measure 10. When I do another CTRL-A, the shading goes back outside the selected clips even after bouncing all clips to clips which should be trimmed.

Select all clips before you change the shaded area in the timeline. That should work.

Thanks for the replies, I have a workaround. I am just asking if this should be normal behavior.
 
Even after bouncing to clips all clips in the project and doing the CTRL-click in the timeline to point to the end of the clip, you would expect that a CTRL-A would only select the timeline length and the selected clips length as a maximum timeline selection. It does not work that way.

I should probably just bug it up and move on...

If there's anything after the clip end, like an automation node, that still falls under the category of "all" when you select all.
