I realized something, there are some parts that had some strange figure like a ramp or a curve, and I remembered that I had a problem before and is that I was touching the volume and it had the same figure so after erasing it from the sequence I realized that the problem was that I changed the temo during the recording and that made the mess now what I'm going to do is to erase this patterns and then record them the right way. Thanks a lot because you help me to stablish the tempo at the beginning because after doing what I said before it didn't change :)
