Divide up song

Ok i got everything down. one last thing i need to know. When i go to mode>song and i pick out the sequences. i made my beat all on sequence one. but i made the hook part and the main beat part on different tracks. so like drums track 1. Beat track 2. Hook track 3. how can i do the change ups in the song window? is that possible? to have it change up from tracks instead of picking the next sequence. cuze i dont want to recreate the drums on sequnce 2 just so i can lay down the hook.

it gives u the option in song mode to copy over any sequence to another , use track mute to switch that shit up

ok i got the sequence copy part down but can u explain the mute part? thanks a lot
