Most commercial (Din) Midi gear that I've explored have pretty much the same circuit as in the above post. Some have some series L and some bypass C.
If you are thinking of 1/8 inch TRS plugs/sockets then some extra protection is generally added in case of a patchbay mishap with Eurorack or other gear.
Otherwise the linked schematic for a 3.3v board should be fine with MicroMod,
