So I am using EQ cuts and volume adjustments, any other tips using sends compression or stereoization etc? Maybe certain plugins?
Having trouble making it all sound like one big sound without losing dynamic range

I have been trying to do this short of thing lately something i have found is that sticking a multiband compressor like ott in the main bus and moving the depth up to like 50% and boosting the highs by quite a lot seems to flatten the sound out pretty well. Then i usually use massive and sylenth1 and just use heaps of freaking unison and change up the octaves on each patch and detune the high octaves way more than the lows then on the patches i low pass them till i feel like it still has the power but very high is gone like it should keep all the energy just remove the crap off the top and then i put high passed noise in the same patch. i think you just only use like 2-3 of these patches then i find the one that sounds the widest and use maximus to make it wider and if u have mid side eq then u can cut the mids out. I usually put a bare nexus in there too since it sounds really good in mono. Also i put side chained reverb and delay which is really important to make it sound roomy like really important. For melodic dubstep i put the reverb time high and future bass i put it low. Something else i might do is stick some kind of atmosphere sound in there like a trumpet or a pad or something and sometimes i stick a super high screechy lead. Also the highs are really important to get that power you are looking for so boost them with ott or layering. Don't overdo the layers just check if they are actually adding to the sound. Scoop your lows out fully too and side chain that bitch and you should be getting something not shit lol

ps use a transient shaper because sometimes i get way to much pluck or not enough punch and it makes everything sound seperate. turn off restarts and retrigs in the synths unless really needed also
