[Jackaudio] Jack2 MIDI on Windows

Probably a long shot because most of y’all are on Linux, but I’m on Windows and trying to use Jack2 on Windows to connect MIDI applications and failing horribly. In QJackCtl the option to select a MIDI driver is just greyed out? I’ve been able to use loopMIDI for a loopback MIDI device to connect programs, but that sidesteps Jack completely which is not what I want. In my testing scenario, I have Pure Data (Pd) running the audio/midi test patch, and Virtual MIDI Piano Keyboard (VMPK) as well, a piano keyboard. I can use loopMIDI to connect the two and Pd will successfully send random MIDI notes to VMPK which it will then play as audio. But again, I want to be using Jack for this instead so I can manage things in one place. How can I route MIDI data between these two applications via Jack on Windows?
