Any FabFilter Pro-L users help with a newbie question?

Just got FabFilter Pro-L.    I have a bass line that has a few notes that hit a bit too hard.    I want to limit those peaks, for example those going over -7db.   I don't want to make things louder, just cut off those peaks (in fact make it quieter).  How do I use Pro-L to do that?   It has a gain slider, but this makes things louder.  If I move the gain with ALT held down it seems to cut off the peaks, but there is no volume decrease.    What am I doing wrong?
 
 

Thanks bitflipper.    The ceiling is the Output, right?    So when lowering the output, this lowers everything by the amount I'm lowering.  And if I use Gain+Alt, this should cut the peaks off that level of the output whilst leaving the rest of the sound unaffected?   At least this is how it looks from the graphical output I'm seeing ...
So if I have for example a piano track where just one note is way to hiugh, I can cut off just its peak using Gain+Alt, and leave the rest of the sound the same as it was?

Great, all clear, thanks for your input.
 

Zo's right about that, for a bus anyway. Zo usually is. But the immediate problem is specifically a bass track, and the peaks are almost certainly low-frequency and can be easily limited by a broadband limiter without impacting harmonics. I've used Pro-L for just this purpose, and it works great. I've even used it for leveling a rock vocal, and it worked surprisingly well for that, too.
 
My only caveat is that with bass it isn't always rogue peaks that are the problem, but often specific rogue notes. For that, a multi-band compressor or dynamic equalizer might indeed be better.
 

I don't understand, if it's just a couple of notes, in a few places? Why not use an envelope? The other tools, limiters and compressors are intended for other things.

Bit , how do you find the Limiter in PRochannel versus the Pro L or Sonnox ....? never used it but i'm in a midlle of a new install and wanted to replace my Master "Safety" Lim by one on the PC ....

Sorry, Zo, I don't use ProChannel, as I am on 8.5. I have never used the Sonnox, as I avoid dongles. I can only compare Pro-L to limiters that I have used: Ozone, Barricade, Elephant, and whole bunch of lesser plugins.
 
I like Pro-L a great deal, for its efficiency and visual aids that make it appropriate for remedial and thickening applications on tracks and sub-mixes, as well as on the master. But on the master, I mostly reserve Pro-L for more aggressive material and still prefer Ozone for everything else.
 
In the OP's particular situation, I would turn to a dynamic equalizer such as Pro-MB or MDynamicEQ, because a) I can apply it to specific notes (and optionally their harmonics), and b) the degree of gain reduction will be a function of the signal level rather than an arbitrary threshold.
