A few things, this did not play nice with a Win XP 32 Bit install and Studio One. There are no real instructions with this. Do you have to license this even a free product and how do you go about it? Poorly documented.
This interfered with the (by stopping) bootup procedure of Studio One after installation. After removing it everything returned to normal. Even though it is VST3 and Studio One works with VST3 it still did not like it at all. It may be a Win 7 thing and I can understand if that is the case.
I have found from experience even with the best loudness meters you can still use a simple but accurate VU meter to tell you the exact same thing! And what do they tell you anyway? Suppose you have mastered 5 tracks and the loudness meter might tell you that the third track is a little softer than the rest. You will also hear this with your ears too, pretty quickly in fact. Then you adjust that track by adding some gain to it but in the end your ears are still the best option for telling you how tracks flow loudness wise from one to the other and also within a track from one section to the other and how much gain you need to add or subtract to even things out. I have rarely seen a great mastering engineer base their decisions on what a loudness meter is telling them either.
Clint all you have to do is decide to work with the K system. Set your cal level for K-14 then track tracks, mix buses and the master for 0dB on the VU meter and you will just end up with a perfect mix that is K-14 compliant. Simple as that really. For professional applications though most clients will not be happy with a master at K-14. They will want it much louder than that. Then you have to sort of leave the K system and start mastering for a much higher level. I still use K system in this way though and just reference everything against a K system ref level. So then it is easier to figure out how much louder than a K ref level you have to go.
