I don't really have a clue how this thing works, so you should probably stop reading here.
I have however, had some great results using it for typical compression stuff and side-chain pumping stuff. Just be aware that there is a switch to alternate between the native language and English. Might help at some point.
This beauty can be quite hard to dial in. It has a lot of controls. These just give you extra power. Knowing what the typical corresponding knobs on a typical compressor do, might help as well. There is nothing overtly flashy or gimmicky here. It is bread and butter stuff. But what Bread! What Butter.
Even if you were a newbie, you would find your way around.
The best thing about this compressor is that it is free. Find your way about it and save yourself fifty-hundred quid. This guy deserves donations big time.
Did I mention it sounds great. That is like saying the latest Iron smooths clothes straight. Oh well.
Just gonna have to try it eh?
To go back to what I originally said: I don't know how this really works. I knock it up. I twiddle a few knobs. It sounds great or bloody horrible. You pays yer money, yer takes yer choice. It is a lot of fun. It is very tweakable and powerful. And free.
Give this guy a couple of bucks. He more than deserves it.
Oh, and it isn't that hard to learn if yo know a bit about compressors in the first place. Just make sure you have the 'English' switch on, or you might be at a bit of a disadvantage. :-)
