Hello, I have a Boss RC-20XL pedal.

I need some help or tips on keeping my loops up to speed with the music. I want the loops to continually stay in time with the beat of the music. It seems that a loop or chord progession will only stay in time for about two passes through and then it starts to veer off.

Thank You
either you/the song is not in time, or you recorded it off tempo.
if you record the loop with the auto quantize function you shouldnt have much of a problem, and there's a tap tempo so if you you're playing live and the time changes, you can adjust
I guess what I am trying to say is I need to figure out how to record the loops in time in the first place.

I'm sure if i do it right in the beginning it will stay the same throughout its course.
