Loop Audio Clip w/o Stretching?

  Hi - is there any way to groove clip loop an audio clip WITHOUT it being set to auto stretch to tempo? Thanks!

     Well - the second I set it to be a groove clip loop, it automatically enables stretching, which I don't want. The problem is that as soon as I loop enable it, it is changing length and speed and no longer fits the song. This seems to be because the "original tempo" it thinks it was recorded at is completely wrong and I have no idea where it is getting the number from. This is happening on almost every clip I record - the original tempo is NOT what the project tempo is at that time.

    Right-click and go to Clip Properties. Click the Audio Stretching tab and enter exactly how many Beats In Clip you want it to be and it will alter the clip's length and therefore the tempo. In other words if you set the beats right you can force the clip to it's original tempo. Another option is to open it in a wave editor like Audition or Sound Forge and modify the internal tempo of the clip to suit your needs; you can set the tempo to whatever you choose and that information is what Sonar is going to interpret unless you "force" the tempo in Clip Properties.

    What is "it"? 
    Are These waves you are recording? 
    "the original tempo is NOT what the project tempo is at that time. "
    what does that mean?
    Is it really that hard to ask an intelligent question?

      "it" is the clip ... yes they are wav files "the original tempo" refers to the original tempo as shown under the clip properties

    Ok, I'll guess.

    If you recorded these parts in the project you are trying to loop in (ie: the tempo has not been changed),
    They shouldn't be stretched when you loop them.

    However, you have to loop them correctly. (First of all, forget the loop construction view. I've never seen a use for it anyway.)

    your clip should be edited to fit into a timeline of x number of measures. So, if you played a part that is 4 measures long but there is some slop, delete the slop at the 1 and 4 measure boundaries (using snap), then, bounce to clip.

    Then, right click on the clip and select the groove loop thing (forgot the name) for 16 beats (4 measures X 4 beats = 16). hit OK.
    this Should work. Sometimes Sonar doesn't get the right beat number. So, if you're getting stretched loops, Sonar probably guessed at 8 measures or something.

    In other words I assumed correctly and responded correctly.  It's a little odd that you ask for help and then ignore and respond curtly (or not at all in my case) to those trying to help. Did my suggestion solve your problem and if not why?
     
    Incidentally, checked out a tune or two and liked your playing. Rock on the Bottom is a particularly cool piece.

    Hey man,

    I've been through this and I have a solution.
    I don't know if it's "right" but it works.

    If the recorded clip is not exactly recorded up to the loop point then it stretches and screws it up, right? That's what I get.

    So I do this:

    Make the clip long enough so it can be made into a "groove clip" without being altered.
    I do this by dragging the start points of the clip and the end points to a 1, 2, 4, or 8 measure snap point. Then right-click on the clip and select "bounce to clip" and this will rewrite the clip as if it were recorded exactly this long. NOW it will groove loop without stretching.

    If this leaves you with a clip that is half empty, then just drag and copy it to an adjoining track so the proper parts alternate and fill in the whole loop.
    It may sound like a lot but you can do this in like 10-seconds.

    If dragging the ends of the clip out to the longer snap points reveals crud that you didn't want to hear - then do a right-click bounce to clip FIRST and it will generate a new clip right there that is ONLY the tightly trimmed audio you had before. NOW you can drag the start and end points and there will be no audio in the extra portions.

    This may sound clunky - but it works, it's fast, and if you rename and save before doing all of it then you lose nothing.
     
    In the event that this STILL causes wrong stretching - then instead of "right-click > bounce to clip" Try bouncing down to a new track.
