I wouldnt roll off all that high freq on the hat, thats basically what makes a hat what it is man! Id just do the usual cut at like 16k or 17k and cut the lows off, maybe leave some on like roll it off with a 12-24db pass but obv always get rid of all the sub freq with most sounds, it will clean up that area, but in saying that, with bass that im gonna have a clean sub underneath, ill cut at like 85 sometimes, as theres possibly some sub overtones at that freq that give a bit more thickness to the sound, though if i use a sine and then a sine octave above i will consider cutting higher, all this sub nonsense is to do with phazing issues, my subs have been more powerful doing all this stuff then when i wasnt at a lower skill level.
Now with the break, i wouldnt duck out all them mids and nice sharp freqs at like 1k man, thats what gonna make your drums cut through a bit more, if you are gonna boost you can practically boost any freq there isnt a rule but if i were to boost a break, id firstly use a proper eq pluging (waves pultec stuff) first as boosting with shitty channel eq is nasty digital sound, and dont roll off them highs too soon! if anything you wanna boost that area haha. vox stuff is fine. in that kick if i were to cut some muddy areas id probably do it a bit higher up, it starts to cut out just after 100hz thats basically all the meat of the kick man! keep some sub in the kick depends what vibe your going for but ill cut around 50-65 all depending, if im making fast drum beats with sustained sub i wont have a deeper kick than im doing like house, or deeper stuff where you want the kick to sub a bit, if i do wanna go like techy i might keep a lot of sub on the kick, just gotta play it by ear with the sub, solo out the kick and sub and stuff just to check, in saying that ill solo out individual freqs in all areas of the track so ill just listen to the sub, then like 100-200, then 200-500 and so on... then solo out individual parts of the track like just drums, bass.... all of that stuff! again with the bass, dont duck that area, well you deffiantly shouldnt have to duck out that freq that is the dirty area of where a bass shines, especially in jump up most deffiantly, if you synthesis your bass' then just try and make it clean to start with, I.e dont make it muddy in the synth and try to sort it out externally, you can have the roughest bass out there but its super clean like it hits at all the right freq, 1k to like 2.5k is your dirty, metallic area, 100-250 around that, is the warm area, warm bass stuff, then 5k is the gloss and the 10k is the fizz which is not completely necessary on bass, but recently on all bass ive got a white noise layer quiet, when you start to distort/saturate/eq and so on, its turns that harsh noise into a nice sheen that just slightly fills that area of the spectrum. the snare, same as the other, dont duck and roll off later in highs, i dont know what that low cut/shelf thing is on the snare but id just completly cut it at like 100 and dont start to duck out freq right before the peak transiet of the snare cause your start to lose that punch, in terms of where that punch is happening, around 140 to quite higher, some neruo tracks and other stuff have snares punching at like 500hz haha, obv 140 is a very low phat snare and if you dont have a good sample of that snare at that freq your prob have a hard time trying to mix it in with a track, espeically if you have a lot of bass around there cause they both take up head room and you want to try and maintan as much headroom as possible while have the most you can in your freq spectrum and mix, but usually the snare will punch at around 200hz. think break same stuff. So lets recap short, TLDR dont duck/cut 1k-2k freq and roll off much later on stuff like hats, kicks can roll off earlier like 10k, even lower if its just acting as a sub and 100-700k like punch and you have breaks loops and stuff with it, low cut sub out of sounds but monitor this and always reference your sounds, frequency areas and most importandly, monitor your whole track on as many speaker systems as you can, car, headphones laptop speakers everything, wear 1 ear on headphone, swithc ears... listening on speakers?? stand up, look to the right/left, up, everything, move around the room in all areas as your track is playing, youl pick up on things you didnt realise doing this. your ideas are good and just need to pursue music making its a long haul journey, this aint a 5 minute thing and some people spend 30-40 years making music or learning instrument only to become a high level master, basically a musical genius. My dad once told me as a musician, some people spend their whole life making one track to finally.. 30 years later they complete it, they didnt spend 30 years on one project, they spent 30 years developing there ideas and combined every idea they thought on track before into this one track, just a thought! But dont give in man think of what you could be doing in 2-3 years time, making money from it? maybe sonner... Hope this helps its a fucking essay and a half but these sort of things cant be said in 2 lines.
