I bought this the other day because I have a good few colored and clean compressors. But the one thing I never truly felt I had was a invisible compressor. Well I demoed this after a bit I had to have it.
I know the GUI is basic but that's the great thing it shows you what the waveform looks like and can be invisible almost like you did not compress anything at times. I love the way this thing sounds and the CPU hit is way smaller than I expected. Even with oversampling on full its almost no real hit. and if you want you can reduce it.
I personally do not use the limiter section because I get what I need with the compressor section alone but the limiter sounds pretty darn good to. now some times you might want to have a very clean invisible compression but maybe distort the signal some what I like is I can keep the audio quality in tact and use the limiter being pushed retarded amounts to distort the audio.
the only thing that I think could be done to improve this plugin in my opinion would be just one thing, If the gain knob basically worked after the compressor but before the limiter. this is only because with the gain working after the section you limit you can peak. with the gain working before the limiter you can use it as a true limiter just a idea but still its basically top quality and top on easy to use hope it helps its cheep and well worth more than its cost. I plan on buying the multiband comp from them soon
