Hi Craig,
I am another that tends to "master" (I use that term loosely) outside of Sonar. I do, however, finalise the EQ on the master bus using an instance of Pro-Q, simply to carry out a low and high cut and use the old "smiley face" curve to drop the mids silghtly.
I'm wondering how I would "normalise" in Sonar though... I know I can use a multitude of compression tools, but I like to see the wave file itself. Mainly because I know, now, what sort of overall shape to expect of a lightly, or heavily compressed audio file.
So for me, at least, I like to export my wave file, open it in Sound Forge, and then normalise (or compress) within that, and while I am there I will crop the track to length, and fade out if needed. And then finally create the finished MP3 file for uploading to SoundCloud.
