Just checked -- In Realband you seem to have everything that Sonar does.

1.) The fader is the same.
2.) The trim is found by clicking the fx icon on each track (next to the Solo button). The trim control is in the lower right of the fx window.
3.) To add gain to a track: Right-click on a track and "Select Whole Track". Then Edit menu --> Audio Effects --> Gain Change
4.) And I think you know how to find the compressor.
