erase problem

when i press erase it´s automaticaly track 1 and not all. it was other way round before. how can i edit it?

i think u can't erase on all the tracks at the same time. you have to choose the specific track(1,2,3,..),where u layed down the sound on it. on that track u can erase the sound. when u have another sound that u want to erase but its not on the same track then u have to find the specific track so it appears on your screen. then u can erase the sound on this track.

ok thanks
