How to automate compression?

[Ronman]

What's the usual way to do this?  I want to add a little compression on the Master, but automate it so that I can vary the amount for different sections.

Automating the threshold control is the way I usually do it.

Turn the knob on your hardware unit.

Hey Ronman,

The same way you automate anything in Cakewalk (lots of documentation of this online).  Personally, I use the write enable button on the channel I wish to automate (and remember to turn it off when you're done).
