I use the punch feature a lot. I'll record three of the same clips 4 or 8 bars long and pic the clip I like. When I put the clips together, I now get a popping sound where the clips meet. I've tried fading. It seems it's only on the guitar clips. I use GTR 3 a lot. But, I have never had these pops before.
 
Any ideas?
 
Thanks, Greg

This is probably being caused by the clip starting at a place other than a zero crossing. Fading should fix the issue. You can also turn on snap to zero crossing.
 
I assume you are sure that the problem isn't that your asio buffers are too small.
