In Ableton I have a strange issue with the MPK49 If you look in the preferences menu there's (unknown mididevice) next to the input and output ports of the MPK49
Even though the MPK49 is recognized by my Mac (See screenshot: http://imgur.com/di3EHtr)
Somebody knows what could causing this ?
I also have to pull the usb cable in and out to make it work in Ableton. (every time when I start Ableton)
