Midi out no output in loopbe

I’m trying to send midi data to another application on the same computer with Loopbe midi but i don’t get anything. I’have midi out active i i can monitor midi stream in maxmsp but no controller , or note, or program change appearing. On Nuendo midi out monitor is showing data only when i push STOP. No record enable, neither monitor on the track. I try with and without instrument without succes…

Did you already troubleshoot using a different virtual midi cable app?

Yes i’ve tried also with Loop Midi, if you know another one working for you with W10 or OSX , i’ll try it
