You should go back and work on Kick and Snare a bit more.
First of all: did you pan the Kick and Snare? Something just sounds weird and it seems as if the Kick is panned slightly to the left.
If you had to work hard on the Kick to make it cut through, I suggest that instead of boosting frequencies on it (my guess is that you did that), you should rather remove those frequencies on the other instruments in the mix or use sidechaining. Another option would be to simply use a different sample if you can't get that one to work in your mix.
Same goes for the Snare. It's way too quiet in the mix right now. And that might be a volume issue but it's most likely a frequency issue as well.
So my advice would be to remove all the effects/processing that you have currently on your kick snare. Listen to the raw samples and decide wether they sound already close to what you would like them to sound. If that's not the case, then try to find different samples. If you can't find any then start looking at the other elements in the mix.
You always want the Kick and Snare to cut through. Listen to the Kick and your Basslines only and start cutting frequencies on the Basstrack(s). Usually you'd want the Kick to be prominent in the 60-80 Hz area. If you have a frequency analyser, you can look where the Kick sample is currently peaking. The easiest way is to look for the frequency range in which you want the instruments to be the most promient and cut these frequencies on the other instruments, with which they might be interfering and try to avoid boosting frequencies too much.
No Panning and no boosting on the Kick. I worked on it, by side chaining the bass, and a few other elements. Also by tweaking the compression on the Kick so it was punching through a bit more. If anything I think I might have done something udesirable in that process.
I am only a beginner, but pretty much I had gathered you got your Sub in the Freq's you mentioned, and that you Kick should be coming through around the 100-150, which is where it is. I left a nice space from 100-200 so the kick could come through. The snare hits bang on at 250, and it is just a balancing issue I think, just needs to be more promiment in the mix, theres still loads of head room left in all my tracks before I did the master channel tweaks to get the mix up.
Will try and give a bref idea of how the frequencies are sitting, please let me know if it make sense or not, like I say just trying to pick this stuff up.
Kick - Cut from 100hz, then added a compressor, then went and added another filter to cut again from 100hz. Thought process was to keep the low end info out of the sub Bass area.
Snare - Filtered at 200hz, to get rid of any low end on it, then some EQ with a 6db boost around 250and I made a cut around 8.8khz, that was just from listening I made that tweak.
Breaks - All low end removed around 500hz, as I wanted them to sound crisp and high endy on the drum loop.
Bass - Split into Sub and Mid Bass, Sub is low passed at 100hz, and the Mid Bass high passed at 230, but I have added a EQ dipping out at 250, and a couple of other points where I was getting harsh freq's coming through.
Anything there I can look at and work on?
Thanks for the feedback, much much appreciated.
