After many attempts mastering the first big killer track for this album I am mastering right now, I switched back to the second model instead of the third. It really sounds good. Yes it has more colour and mojo or whatever but it suits this track better.
The three models sound different so please make sure you listen to all of them. I was on Model 3 for a long time with this track but now I am loving how Model 2 sounds instead.
(Like I did right at the start) I have also found some of the quieter tracks sound nice with Model 3 instead. I need to get my teeth into Model 1 too and find where it sits in the overall scheme of things.
It is a great compressor on a mix. I am pushing it a little harder too now and getting it into -2 gain reduction heading into -3 territory as well.
(only on loud bits) It is great you can switch models on the fly while the track is playing. You do have to readjust a few things though when you do this. You wont get the exact same amount of GR in all three models either. So you need to tweak the input and output levels when you do change them on the fly. But they are often quite close though.
I use to borrow the Smart C2 hardware compressor from the TAFE I was teaching at the time and use it on albums for mastering. It was very nice. In some ways the MJUC is the best software thing I have used that comes close to this in a funny sort of way.
Another very cool thing is that you can look at the GUI in different sizes. I find on a 27" monitor setting the GUI to 125% or so makes it very easy to adjust as well.
