The automation is horrible for Dubstep. The drawing is erratic. You can't get precise curves at the same size. On false move and you are screwed.  It is a real task to then do fast curves and slow curves. Fruity loops does it so much better please take a look at what they are doing and make it happen in Sonar. The workflow on this is 200 times better and Frutiy Loops is way on the bottom of the totem pole. 

actually I'd argue that FL is at or near the top when it comes to automation. sonar, being unable to even freely curve lines, needs a lot of work in this area for sure.
