The only caveat that I would point out about Automap and Sonar is that Automap will control plug ins, but it will not control the Pro Channel (I haven't tried it in a while, but I have never seen anything in Automap release notes that would make me think that has changed).
The sliders and buttons on the left side work well, and the knobs on the right side can be put into mixer mode which make them into pan controllers.
To control the Pro Channel, you will need to ACT map the knobs. This works when the knobs are in MIDI mode. Only downside with the knobs in MIDI mode is that the Impulse transmits them as CCs. In ACT mode, the knobs act as rotary controllers so a right twist increments the current value at the plugin. In MIDI mode, you will see a jump when you twist a knob as the plugin catches up to where the Impulse is. (this is common to any device that sends CCs, not an Impulse problem).
