i find it very similar to cubase in some way. that things you should get used to is that right mouse click is for selection, and that you dont have any group/aux tracks.
basiclly you just have an audio track which can be used as an aux, fx channel, or even parent to it another tracks, so it's like a group track.
also you dont have stereo or mono tracks. each track can include ( i think) up to 4 channels
