Cannot speak for anyone but myself; I always use multiple audio tracks and usually a single MIDI track for Drums
Again, same here. I used to have Cubase 5 before Sonar and in Cubase you could 'dissolve part' which would split out each line onto a new MIDI track which was incredibly useful - only because I used to convert each MIDI to audio instead of now routing to an audio track.
But now in Sonar, 1 MIDI track and 11 audio tracks. Much easier!
