Nevermind, I figured it out. I need to set the button to IA and select the Audio tab, then select the loop. However, I have now assigned the hold function to select a second sound on the chorus via midi. Is there a way to set the button so that when I turn it back off, it defaults to the first sound when turned on again and not the last-used one? Because right now, If I hold the button to select the second preset and then turn it off without holding back to the main sound first, it will turn on to the second preset when turned on again.
