Things missing:
1. Reverb
2. Two algorithms in Maximizer are not there.
3. Other dithering algorithms apart from MBIT+ are gone.
4. Imager misses controls for phase, polarity and delay offset.
5. Gate/expander gone
6. Dynamics histogram view gone
7. Due to the change of GUI the scaling sliders for individual processes are gone
What we got:
1. Nicer GUI
2. Dynamics EQ
3. Standalone app (which I don't really need)
