This plug-in works without any problem on my Mac Pro. It is quite sober processor.
I see that nobody has posted a review on this plug. I'll mine to disabuse those who might think it is just a beast more reverb. Well, you can actually use it as a simple reverb and it is very good. And it is also an echo. But the "reverberation" adds a module gently titled "Animated Object Space Emulator" and thanks to it, we can create all the wildest delusions. The principle is not easy to describe, I refer to the specifications given by KResearch: We have "objects" which can determine the size, resonance, oscillation frequency, the characteristic reflections, etc..
Do not run away! The whole is much more intuitive as you might think and can be easily reached to create reverbs and echoes really original and quite insane that go in all directions. For the more timid, there are a bunch of presets that can serve as a starting point. But with or without it, I'm doing fine without ever opening the manual and when I dub, I enjoy very much with this. I use it for about three years and if I had more, I would do the purchase without hesitation.
