NIcely done piece, and love the video.
Couple questions :
* The ARC2 you said was used for "Mastering" - do you not have that on all the time when you listen from your speakers? Its not a "mastering" tool as such ... and as you had it "ON" during playback, what sound were we hearing, I guess you must of bypassed ARC2 in recording the output?
* The 3 reverbs: what plugin is that you are using? Is it better than the Breverb included with Sonar X3? And in using 3, did you insert all as sends?
