    I'm currently using Cubase 5 at the moment and finding that when I want to drastically cut low end or hi end frequencies, I'm not provided which much choice. Cubases' EQ slopes aren't steep enough for cutting out unwanted frequencies and the filters are shit. It pisses me off, because Steinberg don't appear to offer much when it comes to processing, whereas Logic offer a range of single purpose filters, as well as a decent set of EQ's with multiple slope choices.
    Anyway, can anyone reccomend some decent EQ's or filters similar to Logic's, preferably free!

    Also, I've heard that linear phase EQing needs to be taken into account when filtering with steep slopes, so as to avoid resonant spikes... Can anyone shed any light on this?

    EQ is an EQ, not a filter. Have ago with some of the other EQ's in the effects. If they ain't doing to job try izotope alloy or izotope ozone eq

    But surely you can use an EQ to basically the same effect? :/ Most EQ's have slope functions allowing you to cut both low and highs, the same as a low-pass or high-pass filter.

    An EQ is just a bunch on filters put in one interface : http://en.wikipedia.org/wiki/Equalization_filter

    You should be able to control the rolloff of your filter. This is measured in dB/decade which means decibels gain reduction per change in hz (freq). look for 24db/dec or 48db/dec if you want ONE steep filter.

    You can also layer multiple less steep filters and get the SAME EFFECT. Mathematically filtering is an additive process so 2 12db/dec filters = 1 24db/decade filter.

    If you want a really good EQ (set of filters) get FabFilter's ProQ. Get the bundle if you want, they're all good.

    I have been using multiple filters in series also, but I was going to ask this too.
    Anyone know a free filter like 96db slope and no resonance/colour? Just a super clinical high pass filter to cut low end off stuff without rolling off anything much above that point.

    That's good to know, I may just stick to doing that then 'cause I can't really afford any of the Fabfilter plugins.

    So, in terms of frequency, how much is a decade measurement? Also, when cuttoff slopes are referred to 'poles', is that basically an alternative measurement to the the dB per hz thing?

    the pole is the characteristic point that defines the filter. It is the point on the filter's graphical representation (x,y=frequency,resonance). It is the thing you click with your mouse.

    one decade: http://en.wikipedia.org/wiki/Decade_(log_scale)

    @ subprime: if you use super steep filters to highpass your tracks you run risks of making your low end sound boxy. Better to be gentle down there, and do a mild highpass (6 or 12 db/decade) well below your fundamental. I know people that use a low shelf below their fundamental, and it is pretty clean on the low end to my ear.

    What's so good about the Q filter? :/

    idk if you are referring to what i said about FabFilter ProQ or if this is something else, but FFPQ is great, you can select to have 3 linear phase EQs, each with different latency, or you can select a zero latency mode, the interface is amazing to use, you can solo individual poles, etc. and it has a spectral analyzer you can overlay on the filters, which can be set to display preEQ signal or post.
