Word up Vlasta

Lemme dig right into the compression.

Firstly, for bussing and overall mix compression, never use limiters, as a rule, to achieve dynamic effect.
Limiters are too hard, don`t act musically, and generally have horrible attack and release behaviour for this kind of thing. They generally are too abrupt in behaviour and make things very flat and mechanical.
Use limiters for controlling peaks and transients.

Now a good rule of thumb when you have overcompression like this, you can hear how the compression has sucked the life out of the kick, letting just a sharp "click" thorugh and then some sub?
If you begin to back off the compression attack the kick will start to sound more rounded as the "nose" of the kick starts to poke through.
This is a good way to get that heavy compression sound without killing the kick.

For this kind of super pumped mix I would use 2 compressors on the mix bus.
One giving the pump, and then a second smoothing things out just a little, post pump.

COmpression is very important in techno, but it`s all in the attack and release, and esepcially the attack and release behaviour of the compressors you are using.
Trial and error...........

I like the guitar that comes into this later on, totally unexpected!

Great sounds and ideas overall but it`s hard to comment properly until the compression madness is sorted out.
