Acustica is known to have a rather "combative" attitude online. I honestly find this off putting as in my opinion if you represent a company you should at least try to be calm and not show yourself to be triggered everytime there are criticisms addressed at you. You should be confident, professional and collected. It make you look really bad honestly. (IK used to be guilty of the same some years ago, but have learnt their lesson I believe).
My experience with the company is; I was using quite often one of their earlier free plugins called
Ochre.
Ochre is an OK EQ overall, but has an exceptionally good and musical low band boost that I still use as a special weapon sometimes.
The owner/founder certainly "leaves a mark" on it, as it is
the only plugin I have ever seen that had some cryptic pseudo vindicative sounding writing embedded on the GUI (something about someone stealing his ideas).
For years I was reading about the new plugins from a growing crowd of devoted users. I didn't decide to try it for myself because of Nebula's "complicated" and "particular" reputation. Then a few years after the Acquas came out i finally took the plunge, did a research on the most beloved and rated AA plugins and went for it and bought 3-4.
I found the EQs to be OK, not bad but nothing to write home about compared to the competition and the compressors just plain weird, don't know how else to define them.
The thing that made it absolutely impossible to use for me was the terrible latency between turning a virtual knob and hearing the plugin react. It became unbearable when using them in stereo as my brain didn't like hearing left and right totally decorrelated for seconds while messing with the plugins.
Not to mention the ridiculous and unjustified hit on the CPU.
As the "sound good as hardware" claims, honestly I don't hear it and I have used and still own lots of high end analog devices.
Then there is also the fact they "sample" hardware units, don't mention them by name or share any revenues with the creators of the original sampled machines, still people know exactly what device was sampled as you can find the info online half an hour after every release.
(not sure how I feel about it morally and how I would feel if I spent years and years on developing, manufacturing and releasing an X hardware device to see it then digitalyzed in a few days by a company and sold to everyone)
They have been now releasing plugins with incredible speed and frequency, I think they found an "industrial" way to sample units and they are just churning them out one after the other...
(BTW the bugs that every new version has left many customers feeling like beta testers)..
I perfectly understand and support companies defending themselves from piracy, but if the fact they are so slow and hard on the CPU really depends on their copyright protection and not their inherent
"special-ness", I would find it kind hilarious.
Anyhow, many people do swear by these plugins and love the company, that's awesome, I'm just giving my personal experience and opinion and don't have any personal beef with the company or its users.
