No "to Max 1/2" or "from Max 1/2" midi devices available on Windows 10.

I have a fresh installation of Max/MSP 8.1.10 on Windows 10 that I'm trying to get talking to other applications on my computer via MIDI. There's no listing for the Max-created from/to MIDI ports in MIDI Tester, MIDI setup window, notein/midiin's menus, and they are not available as midi sources/destinations from other Midi applications.

I'm pretty new to working on Windows still, is there something special I need to do to activate those virtual devices?

that midi ports are Mac only.
It is actually mentioned in reference of midi objects.
But it is anyway not really a handy thing , because
depending on order of applications start, one would see the ports or not
if other app started before Max, which creates the ports.
For that reason it is much better to use IAC Midi driver on Mac
or for example loopmidi on Windows.

or

see which works better for you, I personally prefer loopmidi

Gotcha; I've used Max on Macs for ages, and the documentation for midi makes no mention about these virtual ports not being available on Windows. I'll look into loopmidi, thanks.
