What is the most forgiving envelope filter?

The most musical amd natural sounding envelope filter I've ever used or owned, and the one I will now be sticking with, is the Xotic Robotalk 2. Hardly gets a mention but IMHO it's the best there is...

It is up only, but personally that has never been a thing for me. My first EF was a Boss t-wah which did go either way, but guess what, I only ever set it to 'up'.
The dip switches control filter voicing and sensitivity range for active/passive.

But all the more reason to just run some nice OD right ahead of the filter. Set your own dirt just the way you like it.
While you can get good sounds doing this, IME it still doesn't quite match the sound of natural filter drive. I just got a vintage EHX Doctor Q that has it, and of course the Musitronics Mu-Tron III is famous for it.

I liked the Robotalk 2 a lot, but not quite enough to keep it. Setting the two filters differently (especially the decays) yields sounds I've never heard from one box. You can also make it sound like a very cool envelope phaser.
 
Oh man... If I had foot-control of several parameters on my envelope filter, I might never leave the house!
LOL, while I try to find a spot where I never have to move knobs even if I switch something like up/down. I'm stupid lazy about multifunction things: the less I have to do to change functions, the better.

Ha! See, I'm torn: On the one hand, I love that there are so many cool and critical sounds in my palette that I can get from a single envelope-controlled filter, and yet I hate that i need to bend down and move some controls around to get from one sound to the next. Okay, maybe I don't "hate" it...I think I'd rather push some buttons and turn some knobs than call up a preset; in some ways I prefer the purity of the manual approach, especially for creative musics. Perhaps the ideal is to have 4 or 5 identical envelope filters, each one set up with one of my favorite (but different) sounds!
