I'm not 100% on this, but the Meatball and its clones (Meat Wad, The Grinder, etc) have an attack and decay setting, plus an expression pedal control over the filter.
I'm drooling over the Barge Concepts The Grinder. If/when I get one, I'll review this feature, as I've owned a BMS before.

But it doesn't do the attack delay to my knowledge.
