I stored like a 15 minute song on my boss rc-20xl and now every time i go to start a beat it will like restart and all the lights will start lighting up. Also when i got past that stored preset it lights up. I just had it on batteries so i was wondering if there was a way to reset it all without having to turn it on. Also i try to delete the song but when i go to that preset it restarts. Anyone else have this problem?
