Hi Bob,
The easiest way for me is to use a midi controller.

However you can draw midi commands in both Sonar and PT. I start my songs in BiaB and finish them in Sonar so I do not know it BiaB allows CC drawing. You may want to check the manual on that application.

Many times I will use the midi controller then fine tune it via drawing.

I hope this helps.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
