Oh and plus 1000 for the Arranger track thingy.
Well in the spirit of pre-announcing things

...while you're waiting, check out the next "Friday's Tip of the Week." It shows how with one click+drag and one right-click+select, you can separate sections of a song into blocks you can then move around to change the arrangement.
The week after that, I'll show how to create a simple scratchpad in SONAR which can have its own tempo, processing, looping, etc. It's real handy when you want to drag a verse or whatever over to the scratchpad, mess around with it without disturbing what's going on the main song, then bring it back in (or not, your choice).
