Hey, pretty simple kweshin... I'm dual-micing my first guitar tracks and I wanna make sure they're in phase with each other. It's pretty close - if I flip one track and nudge it left or right by a millisecond it sounds fuller. I know fractions of milliseconds can still be a big deal though, and Sonar doesn't let you nudge by any less than that. Any alternatives I can use?
