I have heard that one could run low pass/high pass filters to make the kick drum and bass more distinct. I guess there may be a way just thru eq, so I'm looking for a general(not necessarily best) practice on separation. Or is there a video somewhere? I do have that nice frequency chart you guys told me about, but I still need to frame it........
 
I can't seem to see thru the weeds to know where to turn now that we are in the mixing stage...

Watch the first 5 minutes of that video. (Edit: Actually the bass gets revisited at the 5:32 mark).
 

That's what I'm talkin about!!! Thanks!

I am not sure if Dan actually uses the term "mirror EQ" in that video, but that is the term you are interested in. Typically you do not want to boost anything more than 3dB (can be very noticeable), whereas a mirrored cut of -6dB or more is more transparent. This is why he revisited the bass at 5:32... rather than boost the bass, he cut the guitars to give the bass room.
 
If you want to delve more into this, Google "mirror EQ" but Dan hits the main points rather fast and furious in that video.

If I'm not mistaken, this should translate well to Prochannel?
 

Absolutely, the concepts of what he did in that video are universal. It just "happens" to be specifically focused on a plugin, but any EQ of your choice works (more resolution and frequency spectrum analysis the better).
 
Another free plugin that is priceless is Voxengo SPAN for spectrum analysis. It does not contain EQ capability, but can be put anywhere you can place an audio VST. This is good for situations of drastic EQ with an EQ that does not have pre/post spectrum capability... can drop SPAN on either side of any effect.

Another free VST you may want to consider is TDR Kotelnikov. This is a compressor though, and is not modeled after any analog counterpart so makes full use of digital processing. The "gentleman's" edition is the paid version, but I do not have this - the free version is quite nice.
 
Specifically what I like about this plugin is the "delta" button, which only passes the change you have made in a signal. For new users this is incredibly nice, since you can easily listen to the delta until you hear the bite of it (you can hear "intelligible" portions of the original audio), then back it off. It may be easier than trying to hear that same "bite" when the actual signal is still passing through.
 
This is not specifically applicable to mirror EQ though.

One of the many (but most pertinent to my style) advice Mr. Danzi provided me many moons ago is with kick and bass make a choice.
 
Do you want fuller/bottomy bass sound...
 
OR
 
a fuller/beefier kick sound?
 
And the inverse of that question...
 
Do you want a tight bright bass sound with lots of pick attack...
 
OR
 
a tight/clicky bass drum sound?
 
 
It's the same question with the same answer posed in different ways depending on what is most important to you.
 
If your answer is either you want a full bottomy bass sound OR a tight clicky kick then you remove more low end from the kick drum (with a "hi pass" EQ and any other band adjustments needed) and focus in on the beater attack. Then you reduce the pick attack/higher freqs of the bass guitar while allowing the lower freqs to remain.
 
If your answer is you want a beefier kick OR a more defined bass guitar you do the opposite. Focus in on the pick attack and mid more mid range tone of the bass (again with a "hi pass" and any other EQ adjustments). On the kick let the low end stay audible and remove the hi freqs and beater attack as needed.
 
Essentially the low end meat of the kick and bass live in the same freq range and so do the beater click and pick attack.
 
Bass Low + Kick Beater = Good
 
Kick Low + Bass Pick = Good
 
Bass Low + Kick Low = Nope
 
Kick Beater + Bass Pick = Nopety nope.
 
Totally broad, generalized, oversimplified and n00bish interpretation of this principle but I've been playing with it for quite a while now and it works.
 
Also realize that in most cases, unless you are doing bowel churning electronica stuff, you can safely remove pretty much everything below -20hz with a hi pass filter. It just adds mud and clutter in rock/blues/pretty much everything mixes.
 
Cheers.

There is no reason to carve frequencies unless it is an issue.
 
your job, is to learn how to detect issues.
 

Hello kind sir, I kind of think that I know where you are coming from.
 
I struggled mightily with the same issues
 
There are a multitude of decisions to make.
 
I do not know you, or what your background is, but
 
The main thing you need to decide is if you want to emulate someone else, or expose your inner self.
 
Louis Pastuer said "chance favors the prepared mind," or something like that.
 
Less is always more, except when it comes to doing the grunt work, then more pays off.
 
Wish I could help you more, but that's all I've got.
