There is no option for "MadMapper In" on Windows.
Windows doesn't support "virtual MIDI devices".
You have to use a MIDI cabling software that acts as a hardware but just redirect MIDI messages to another virtual device (IN & OUT).
You can use LoopBE it works fine.
Or google for "virtual midi cable windows"
If you just need "sync" you don't need MIDI, you can use Ableton Link (you won't receive MIDI notes or MIDI ccs but just the tempo - bpm & phase - information).
To do so, in the master tab check the "Ableton Link" button, and do the same in Ableton Live: https://www.youtube.com/watch?v=0MbcimSV2VY
