[Solved] Can't stretch audio

X1 Producer user - Trying to stretch an audio clip.  When I highlight the clip and menu/process, the length option is not active.  What am I doing wrong?  Thanks.  Larry Wilson 

Thanks SO much.  That explains it.  How do I convert a groove clip to a wav?

Scook - Never mind...my too quick question above...figured it out.  Nice to know I can always get help here.  (I use Band in a Box and often have to stretch audio to make the fills sound decent.  BiaB 2016 converted all their so-called real tracks to acid loops.)

Thanks Scook.  That's faster than what I came up with.
