I can't imagine anyone still needing MIDI-OX for those old versions of Windows. MIDI-OX 7.0.2 is available for download as always for Windows 7, 8, 10, 11.
Agree, of course, but in the (far) background are (a very few) HW folks still, using old stuff like Win XP even. They send private (question) messages, not wanting to read "You should update" messages.
