Watching the videos and reading the "What's New" newsletter now, but not ready to commit to $150:
1. The new QuadCurve EQ with underlay spectrum analyzer looks excellent! It's what they should have done back in the X1 days! I know I submitted a Feature Request asking for the EQ over an analyzer. Me plus a thousand other disgruntled fools. After all, it only makes sense.
2. Self-scanning VST folders = time saver.
3. Custom track-color widget = perfect implementation! Too bad even preference-based colors in X2 never worked right. I'd be curious to see what issues come with the color widget.
4. Addictive Drums looks like it is about 100x better than Session Drummer 3. Less kits though, but can SD3 kits be loaded into AD?
5. AAS instruments; Strum Acoustic Session looks interesting but could be frustrating.
