Hello! I use Vegas 4.0 as a music digital recording studio.  I have a problem, while recording vocals over the music I hear a split second delay or echo.  That throw the vocal off sync with the music because I am record to an echo.  I thought it was the soundcard, so I got another one.  A guy at the local music store told me its in my Vegas program?  Something about choosing a function in the program where it doesn't use as much ram from the computer.  Can anyone help me with this? I am stuck!
