Ok, trying to record a guitar track.  I want the whole project to be 70 bpm.  When I first created the new project, I changed the tempo to 70 bpm.  I record a guitar riff.  I try to Groove Clip it.
 
Everything goes wrong at that point.
 
First, how do I make the entire project 70 bpm?  I think that is why Grove Clipping isn't working right...  If that's not the way to fix it, please give me some help in the right direction.  I'm not a very good guitar player, so I can't play the whole song through, I have to do it in pieces, Groove Clip them, then copy and paste them throughout the song.  Or at least that's how I think I have to do it.  Any other suggestions would be most appreciated.
 
Please speak plain English on this one, I'm new to the whole Grove Clipping and only 4 months into Sonar.
 
Thank you!

First thing I would say is that you don't have to groove clip an audio clip to copy and paste it. I wouldn't advise it if you don't have great timing.  You may want to lay out the pieces and then try using audio snap to correct timing issues.

I need more detail. Is the issue that you have guitar clips at other than 70 BPM which you want to play the correct number of measures with the project tempo now set to 70 BPM? If so, there's a real simple fix.

I don't think I understand the question either. What goes wrong when you groove clip? If you have set the project tempo to 70, and that's used when you track the guitar, shouldn't it be ok?
 
As mentioned, Groove clipping is not necessary when copy pasting clips, but I guess your problem is that the clips are not of "usable" length. If you record a guitar riff of 4 bars, but the actual length of the clip is not exactly 4 bars, the first copy of the clip starts at slightly wrong time, the next one doubles the offset etc.

Curiosity compels me to ask ...  Why is it called "Groove Clipping"?

It's the SONAR equivalent of an Acidized clip - stretch the end and the clip contents automatically repeat.
 

A groove clip also follows tempo and pitch changes, so it maintains its "groove" even if you speed up or slow down.

I guess what  am really asking  deals with the origin of the term "Groove Clipping"  ... its etymology.  Does it arise out of a throwback to the days when recordings were done by creating grooves in a "wax-like"  media?  What about clipping?  A clip  I think I understand as being a segment of a tune or of an audio signal. So clipping would mean to me the selection and separation of that selected segment from the rest of the piece.  
 
But that's just my take!  What is the real story?
