[SOLVED] Groove Clip Looping Problem

I used to be able to select a part of an audio track and apply groove clip looping and it would maintain it's tempo. Now it either stretches or shrinks it and therefore makes it unusable. I'm pretty sure that it's a user error. Can someone point me in the right direction to get it to return to it's old behavior?

I used to just split it where I wanted it to loop from, right click, and apply groove clip looping.

Usually imported
 

Then I suppose there are some kind of time stamp to them, which needs to be removed before a new groove clip will be created correctly.
I could be wrong, though.

I'll give it a try

I've tried that, but most of the things are greyed out and anything I try seems to not fix things. I've lately just worked around things by manually cutting and pasting the same piece of the clip. Not nearly as nice as it use to be for me.

.WAV files

OK, what I do is take any audio track and drag it into SPLAT. Lets say I need to add additional vamps to the song. I place the cursor at the beginning the vamp. Split the track at that point, and split it again at the end of the vamp. I now have three selectable clips. I move the last clip out of the way, select the vamp and right click and pick "groove pick looping." I'm then given a dialog box that informs me that things outside of that selected clip will be discarded. I click OK. I then see that the clip has either stretched or shrunk. I can then drag it out and get the extra vamps, but they are no longer at the same tempo as the remaining clips. It seems to me that groove clip looping always wants to match the tempo of the template I'm using, not the tempo of the songs I've imported. I've tried importing lots of different audio tracks from different sources and get the same results. Maybe its my template? I'll try a different template to see.

It didn't use to work that way for me. So I guess that my workflow would have to include detecting the tempo of the audio I import? What if the song has varying tempos? I wish it were simpler. Anyway, thanks Craig for your helping with this. If you find a setting that changes this behavior, that would be awesome.

Thanks Craig,
 It must've been a crazy coincidence. I tried the tempo mapping ARA melodyne thing. It'll have to do. It for the most part is an amazing feature. It doesn't work all the time as I'm usually editing musical theater music which can be ridiculously complex and subtle in its tempos.
Ha! now that I remember, I realize that it always worked perfectly when I was working with midi. It all makes sense now.

I'll give it a try! Thanks!
