Midi mapper not working. I have been using PT pro 14 for years and today it says midi mapper won't work with some versions of Windows. I have Windows 10 but have never had a problem before and I use the software regularly. Help!

Do you have another MIDI driver available?

Normally you can go to Prefs MIDI Devices and select MS GS Wavetable synth.
A lot of the time this works better anyway. I haven't used MIDI Mapper since Windows 3.1

PWC:
Just for the record, as you're probably sorted now, Microsoft MIDI Mapper was removed altogether in Windows 8 onwards. (Just one of the many things Redmond didn't bother to tell us users.)

Here you can find an excellent discussion of history, implications and workarounds:-
