1. When you say cut out any frequencies over say 90 hz, does that mean when i throw a spectrum analyzer on my drums or something that the frequency should peak here or that there should be absolutely no frequencies over 90 hz?
A filter that actually "cuts out all frequencies above x" is called an "ideal LPF". Such a thing doesn't exist. Well, it does, but it's neither practical nor a good idea to use for various technical reasons. When people say "cut everything above x" or "stick a LPF on with a cutoff of x", what they mean is "use a filter that starts rolling off around "x. In other words, if x=100Hz, then at 200Hz it might attenuate by -6dB, at 400Hz by -12 dB, and so on. You can see this on the LPF section of any standard EQ curve -- everything doesn't suddenly drop to minus infinity at the corner frequency, it "slopes" downwards.
On a spectrum analyzer, you shouldn't expect to see exactly the same slope, unless you started out with white noise. Rather, what you should see is the same signal as you'd get without the filter, but with the level above frequency x starting to fall off, the higher you go. Try enabling and disabling the filter and comparing the spectrum.
This is why there's no point low-passing a pure sine sub: a pure sine is a spike on your spectrogram. If you stick a LPF on it, you still get a spike on your spectrogram, at the same frequency. It might just be a bit quieter, that's all.
2. Also when splitting up your bass frequencies, what do you guys usually do. Say i am using massive, would you pull in two or three instances of massive and eq each one, or just eq one instance of it?
I would do the former, so that you can use a different patch for your sub and for your mids and process them separately.
3. When creating a sub for the track, should i create a completely new instants of massive for the sub or just use my already existing basslines for the sub?
For a sub I'd use something less heavyweight than Massive, for a start. But apart from that, I'd use a pretty much clean patch, with the same MIDI clip as you're using for the mid line.
