mpMidiUserClient going crazy

Upon pluging my beloved A4 and trying to use the Overbridge, I noticed in my Console, a strange message repeating over and over and killing some CPU.

This seems to be a process related to the kernel?

The message is as follow, and google has brought no results at al ?!

mpMidiUserClient NULL!

I’m running OSX 10.9, and the A4 is plugged to my screen / USB hub. However the same behaviour happens when plugged directly…

i get the same here , using with digitone , digitakt.

not sure if problem…

I recommend that you report the problem to Elektron according to these instructions:
