I have had this for a while now actually I bought all of the klanghelm plugins when the big brother of this compressor came out I love that one best comp I have heard in its class.(I mean class by it can basically do anything clean dirty sound like shit or transparent and limit)
Like the person before me I find this thing a gem free looks cool sounds really punchy or smooth depending on the mode you choose.
What I like best is its stable and sounds great with only one button and a volume knob.I actually started using it as one of my go to compressors for stuff that I want to dirty up or just tame if its to dynamic(drums or vocals)
Its a very simple yet powerful beast of a Plugin that I really really enjoy using. Also it has 0 latency so if your tracking you can use it.
In my opinion it sounds great and really gets stuff to sound beefed up or smoothed out depending one what mode you use.
keep in mind no other controls than what you see the Vu meter shows gain reduction and there is no limiter control or wet dry but still its a great peace of work.
There are two modes one has a more dirty compresses sound the other more of a clean sound enough said its free and works on windows mac 32 64 bit. Just download it and if you love it get the big one its even better
