In looking at the video, I was pretty impressed with the compressor. It did not knock me out, but it was good. Ok, I have the Waves Mastering plug ins and it includes a multi band compressor. It took me a while to learn it since unlike other compressors it has a range control which is a blue line that you can make thicker. This shows you how deep on each band it is effecting when compressor or expanding. I really enjoy this compressor because it is linear and does not add artifacts to the music.
I am not interested in another linear multiband compressor as I could use my money else where that would help my studio more. However the new UAD compressor has a great visual look and if you have experience with multiband compressors, you should be alright. If your not used to using one, you may get confused with how to use it, just as some had problems with the Fairchild.
The Per. compressor graphic screen in the middle reminds me of the Steinberg multiband compressor. That compressor as well as the UAD have the upside down U (like letter U) bands that you control. Both also have a more linear and classic sounds options to choose from with the classic adding a little color. If I did not have the Waves Mastering plug ins, I might be tempted in getting this UAD one. I would compare it compared to the Steinberg compressor.
Computer Music just had a dedicated issue on Cubase. In it they had a special section on mastering and explained how to use the Multiband compressor in Cubase. It had some insights that I never saw before. So I started using it and found it to be very helpful. It did not act the same as the Waves multiband compressor, but in some applications it did very well. Like the UAD you have the upside down U to work with on each band. The UAD seems to give you more control, but I cannot comment on it until it is out and can try it out. Remember a compressor just take signals up or down, and most add some character to the signal, some good, some bad. But it does look like a winner for those who know about mastering.
