The RC-30 is capable of two channels. Basically, I can record one loop on one channel, and another (of equal length) on a second channel, and I can turn them on and off independently of each other. It's super cool! I'm learning a lot about percussion arrangements and simplifying drum patterns to be played on different part of the guitar, and I'm also learning a lot about harmonization and how to harmonize with myself.
You can get a taste of what this looks like on my youtube channel, through my cover of Royals by Lorde.
I plan to loop Superstition by Stevie Wonder, and Blank Space by Taylor Swift. I can't wait to make some videos and post them! Comment what covers you'd like me to loop!! Thanks lovelies!
