Hey John, it’s not a specific setting, basically anything with the envelope switch in “down” mode will give you similar controls to the Moog LPF.
So I was wondering how hard it would be to make an envelope filter effect using just an envelope and a filter, and it turns out, not very hard 
Probably not clear what’s going on there, I have an envelope modulating the filter cutoff, with a high Q. This is the simplest envelope filter you could possibly make. Took a few seconds.
Sounds pretty awesome with a chorus on it as well:
It’s been almost a year since I created this topic. Just thought I’d come back and check in with it.
I still haven’t acquired an envelope filter. Too many pedals, too little time.
I’m still lusting after either a Proton v4 by 3 Leaf Audio or Micro-Tron IV by Mu-Tron. They are both so smooth and pleasing to the ear.
However, I will probably end up starting with an MXR Bass Envelope Filter.
Much more affordable than either and when it comes to the Proton, much more available. So few Proton’s are made that people on TalkBass usually post them for trade instead of for sale. Using them to acquire other very rare pedals that don’t typically come up for sale. The rare pedal market is a weird place.
Over the years I’ve owned 2 Bass Wah’s (Morley and Jim Dunlop) and the following Filters
EHX Bass Balls, Ashdown Filter, Boss AW-3, EBS , Dreadbox Kinematic and whatever else I can’t presently remember
My two current filters are the 3Leaf Audio Proton v2 and the SGFX Supa-Funk . Both I like a lot , probably prefer the SGFX it’ seems to not “fuzz” out and can get a nice wet funky bounce
Filters are definitely a personal touch thing, always try before buy where possible
I would like to try a Moogerfooger and also a Seamoon funk machine
I ended up with the source audio C4 for this because it’s possible to have the filter frequency track the note being played. It gives the option for every note to be equally funky rather than setting a window of most funky.
