Beautiful compressor and finisher
I don’t get why people are upset with this not being offered for dsp. Why would you track on a mastering compressor when there are many other options already? This plugin imparts a nice width, color and sheen to your mixes in a very natural way. Controls are fiddly, headroom knob will be your friend. Love it! Another plugin I didn’t know I needed (and I probably don’t need it) but it sounds like a record

Capital Mastering Compressor
Took advantage of the Labor Day Sale yesterday and bought the Capitol Mastering Compressor, and was able to spend much of the day fooling with it.
To begin with, it is very smooth, light and nicely gluey with some natural warmth and a little tone that dials in or out nicely.
I will often run through different sub busses at some point when mixing, looking for whatever. This compressor when placed on a track with a Pultec and/or one of the Eqs with an "air band" or some such feature for boosting at the extreme high end will very nicely rein in the harsh or nasty that sometimes can show up using those tools.
I like it and will use it. Built a strip that I saved with it kind of sitting there in the middle, just touching stuff.
It improves things.
It sounds strangely LA to me, but that is likely just the power of suggestion emanating from the name.S. B

If no uad , then that's some bullshyt
Yeh I said ,
Please keep the support for UAD-2, we bought the hardware so that the plug ins run off the cards and apollo interfaces. Put out a 16 core card or somethingB. Carruthers
Native Only
WTF
D. Warren
travesty
I wanted to purchase and demo product and it wasn't showing up in my Apollo plugin list...After researching I see that this plugin in native only...huh wth???? what's up with that??? UA thats not acceptable
K. Thura
Good For Mastering and mix bus.
I Really Like This Plugin.
R. Williams
Nice sounding compressor but...
Sounds great, love the vibe it gives, but I was expecting it to work with my appollo x16 not just Native, I thought I could save on CPU and was one of the reasons I bought it, shocking, will be more careful in future now UAD seem to be favouring NATIVE.... :O
B. Luyben
Wonderfull plugin (UAD-2 is not a thing anymore)
Did demo the Plugin and liked it although it could have used some modern features and a more readable interface. We all know UA does not care about readable interfaces (customers begging for the resizeable GUI for a decade almost. UA also don't bother to make a UAD-2 version and don't want to disclose anything about the intentions of keeping AUD-2 alive. It's horrible to read all these people asking for the same. Why is UADx up to date and does UAD-2 feel abandoned.
S. Potts
confusion of it all
I would love to buy this but I gotta tell you man the process of what runs on what and why has really slowed my purchasing of UAD plug ins. I just used to buy a plug-in and it worked on my system now with all the varieties and subscription plans etc. it's just way to complicated. 5 Years ago this would already be in my cart.
R. Studio
Nice musical feeling
I've only had time to use it on backing vocals bus, but I feel like I'll use this often in the future .
D. Marais
Gorgeous, but please make this for Apollo too
This plug-in deserves five stars for its beautiful, velvety analog punch, but UA should really make this - and all future plug-ins - for both the Apollo hardware and native platforms.
It doesn’t seem fair that longtime loyal customers who invested in the Apollo units, at great expense, are suddenly seeing UA plug-ins not being supported by the Apollo hardware. The fact that we cannot use these native-only plug-ins in Console just seems like a major oversight. Please do the right thing and make your plug-ins fully functional on both platforms.G. Merino
Almost perfect…
This plugin surprised me a lot. Honestly, I can say it’s my new favorite compressor for almost any use in mixing and mastering. Absolutely incredible.
I’m only giving it four stars because it can’t be used with DSP on my Apollo. I have no idea why UAD did that, I really hope that it could be solved soon.C. Jenkins
Great sound! Great product!
Tried it one mix. Exactly the sound I was looking for. Kept the musical sound of my song - but made it bigger.
E. ARRUDA
Beautiful!
Very natural when inserted in Pianos and Strings. Great glue on the battery. Perfect on the MixBus.
M. TRAP
At the moment ....great sound
I think it's premature give an evaluation clear but until now i've found that this plugin is real good. Great sound.
I don't know if it's real plyvalent ....see later.....great work!J. Lowery
Unbelievable!! The saturation and harmonics are unprecedented!!
this thing brings out incredible harmonics that you weren't aware was even there. going on every mix & mastering bus!!
H. Toapanta
POR FAVOR UAD
Soy de España y como muchos de los compañeros esperamos que UAD saque la Version Apolo ya que hemos invertido mucho dinero en equipos como para que nos dejen aun lado, UAD LEA Y DE UNA VEZ POR TODAS SAQUEN LA VERSION APOLO no solo Nativa.
