 So the sync thing has two control buttons, which are located down here at the bottom of the panel. Mic set. Mic set is fantastic. It lets you set your gain staging of your mic. So when I tap that, it says, hold set mic gain, so you hold it. And then it says, sing your loudest, yes! That's really helpful for when you're performing in live situations. It's going to prevent you from peeking out and feeding back. Tap tempo down here. For every song that you're doing, if you're going to be using a delay, I recommend getting the song to start and then you just start tapping along to the beat of the song. And that's going to make all of your delays work really nicely with the song that you're performing. And those are the control buttons. Thanks so much for watching.
