Look under mixing and master section of the forum or do your own research.

It's good you're asking this question in this part of the forum, and i will answer it in this forum's way.

You have to consider the sound of each instrument/layer you're putting in the track.

EQ can only help so much before the frequencies build on each other or you just have to much of many things. In that case, you should of just used one instrument instead of multiple.

Look up an instrument frequency graph and try to listen to every one of those instruments on your production monitors.

It'll help get a feel for what ranges they are being played at.

Once you've done that, with new found knowledge, listen to your sounds and IDENTIFY the ranges they occupy. You can use an anlyzer, but your ears are what needs to be the judge here.

You need to consider the meat of the sound and not the outliers. The outliers will need to be tamed, but only so much other wise you'll loose their characteristic.

Once that's done, play it in the mix and go from there. The rest should be a mixing/eq/taste decision.

Identify the ranges you're working with and know what you want to do. That should give you better clues as to what to do.

This brings up two questions for me.

- Is it a general consensus that if the entire spectrum is not filled up between my highest end and my lowest end that I should fill those spots with atmosphere / percussion / synth etc. ?

- If I have synths layered on each other (same ranges) and it sounds muddy, lets say the route I take is to take one out. I have now taken one out and the synth sounds weak / amateur. How would I make it sound full / professional? Am I to add another synth and hope it mesh's well with EQ or whatever else that needs to be done to it? I hope you understand what I mean by amateur, but I guess I don't know how else to put it at this moment.

I'm so upset that it freaking deleted my other response.

sounds good man, thanks.

i have great equipment though, but it really is self doubt to defeat i feel like.

i own yamaha hs5, akai mpk61, s4, maschine, focusrite 2v4 and pioneer hdj-2000s

thanks man, ill try to get on pming you tomorrow, its bed time though here.

You should try to be more specific with your questions! There are so many things that could go wrong in what the title describes. A sound example would help a lot.

One thing that will help avoiding muddiness in chords is to use notes sparingly in the bass frequencies, especially when using a harmonically rich sound. The harmonics will quickly fill the bass spectrum with unpleasant "rumble". So for example, if you make big supersaw chords, you probably want to avoid a third or even the fifth in the bass frequencies.
