How many of you are using ProChannel EQ to “roll-off” low end frequencies on your tracks?
The big question for me in this regard is: what slope should typically be used? A gentler slope = a less extreme sound, but also less reduction of low end frequencies.
I would love to hear thoughts on this.

only ears can decide this brother.

it depends on the material also,i listen to my songs sometimes along with a good low end spectrum display and look at the low end from 100hz down to about 20hz Listening through only the sub sometimes and determine what sounds good using several slope settings..

It's funny but even when I roll off everything under 300mHz with a steep curve, the Blue Cat frequency analyzer still shows activity all the way down to 10Hz, but the Vonexgo one shows no activity. So I don't know what's going on down there. As for slope I tend to go no higher than 18 for a roll off. 

I think it depends one why one is using a roll off of the low frequencies.

If you're getting rid of mud but you have some useful content there a sharp quick roll off makes sense. If its just getting rid of unneeded frequencies that don't have a lot of content a more gentle curve would be wise.  For example a guitar has few frequencies in the bass range. One can roll that off with little concern about loosing useful content. But you don't have to be harsh to do so.  However say its a bass guitar you my want to get rid of everything below 50 Hz. This may not leave you room to be gentle. Thus a more severe curve may prove to be the way to go. 

Of course it could be just the opposite.
Judgment and listening has to be your ultimate guide.

Been doing it since the old Sonar EQ. Depends on the application and other tracks. I use low-end rolloff to make room for certain instruments (kick drum, bass guitar/bass synth) to not compete for the low-end with other instruments. I also use it for cymbals/high-frequency percussion to make them more transparent sounding and less heavier.

yeah, sharke, i hear ya.  and the cakewalk analyst shows all kinds of activity.  i'm never sure which one is closer.  i thought for a while the analyst was picking up lfos in synths (i.e. i suspected a bug) but i turned off all lfos and just used a sin wave sample in rapture i still got activity. :/

I always use it, or at least.... TRY to use it in the way that John describes so eloquently above. Obviously, an accurate monitoring environment is critical in making these decisions, but I am not blessed with this. 
However, with ARC2 I'm now able to get closer to what's right than what's wrong. If anything, I would rather be bass light than bass heavy as nothing sounds worse to me than overcooked and muddy low frequencies. So until I have the environment to 100% trust what I hear... And that includes my ears, that is the route I take, right or wrong.

Personally I like to use 6db per octave slope for both high and lows, although sometimes I use the same as the waves SSL channel strip which is 18db per octave for high pass (low cut) and 12db per octave for low pass (high cut) I assume that's what the real boards use since its supposed to be an emulation? Not sure how that would translate in the ProChannel EQ though (emulation wise)

The ProChannel hi and low cut filters have slopes ranging from 6db/octave to 48db/octave in 6 db increments - so lotsa choices there..
