Hi,br
There is something i noticed in many tracks, which isn’t explained in any tutotials. br
In the build up you have chords and a melody which are really loud. But when the Chorus starts and the Kickbass comes in, the synths lose their Volume. It’s not just the sidechain. They are just not as loud as before the chorus. A good example is Michael Calfan - Resurrection (Axwells Recut).br
My first idea was that it is up to the limiter but I also use a limiter and I never have such an effect. I hope you can help me 
it sounds a bit like the Synths are reacting to the Bass.
That’s a matter of hard compression and limiting if I’m not mistaken.br
When the biggest signal (the kick) is gone, the compression makes the other instruments/sounds much louder. When the kick drops back in again, the compressor will be dealing with all sounds again for compression. br

This is something you mostly hear within the popular EDM genre. Other house genres have less of this artifact. Rock and other acoustical music hardly ever have this.
Well I tried it and it only works if you have a compressor on the whole track. But I do not think that this is the right way to do it… But good idea
Hey, just had a listen to that track and that is for sure side chain compression and possibly just automating the volume on the main synth. You can hear how prominent the transients are in the breakdown and then hear they get sucked out when the kick comes back in. Clever side chaining the main synth to the kick would achieve this.
From a signal point of view, the drop will be the most powerful section, its just you’re hearing the treble a lot more prominently in the builds. This is normally due to the compression/limiters that are applied after the mix has been finalised.
