I've been doing this in Sound Forge for years with long audio files, but I'm curious if I can do it in Sonar.
 
I want the cursor to automatically move to the beginning of my selection on the audio clip, and play only the selection looped when I hit play. I want to move the ends of the selection, and have the cursor follow if I change the beginning and still loop. I then want to save just that selection, and move on to a different section.
 
I tried selecting the audio, then looping the selection (this part was easy), but the now time doesn't follow and I have to continually adjust the loop selection in the timeline, which is way to convoluted. I copy drag the audio to another track, which is easy, but getting to that point is taking too much time.

I have absolutely no idea what you are attempting to do... but then again I'm only moderately clever.
 
More deets?
 
Kind of sounds like a task for the Matrix but the "saving" bit is throwing me for a loop (uh... no pun intended, lol).
 
What exactly are you trying to accomplish?
 
Cheers.

I load an improvisation audio file that's 30 minutes long. I then cut snippets out and can end up with hundreds of edits out of the file.
 
Current process: I highlight what I want in Sound Forge. The cursor in SF immediately moves to the front of my selected audio. I hit play, and it loops the selected section as it plays. I adjust the front and back ends of the selection, and SF automatically moves the cursor to the front of the selection if the audio isn't playing, and when I hit play, only plays the selected section of audio. I then right-click on the selection, and save it as a solitary file. I then import the audio into Sonar as needed.
 
It would be easier to copy drag the selections in Sonar, but lining up and looping the selected audio is a pain in the butt right now. I've never used the comping tools, so I may look into that.

Easy! Click on the clip you want to play, then Shift+Space bar. Only that clip will play, it will start from the clip beginning, and it will loop.
 
If you change the loop length, click on the clip, and then type Shift+L. The loop brackets will now match the clip length.
