Send midi to Ableton with Digitakt

Hello hello…
Some help please.
I work with Mac and Ableton 11.
I use overbridge to connect my Digitakt.
I want to use some mdi tracks on my digitakt to play with vst or to change some parameters during live performance… but it doesn’t work. Ableton receive any midi from digitakt.
I think it’s strange because when I record digitakt, Ableton record midi CC from digitakt.

If someone have an idea …
Thanks
