MIDI don't work

[wilfors]

Hey guys,

I recently tried out to vj. Yesterday i connected my Akai mpk mini to arena and it work like a charm.
Later on i restarted my computer and all of a sudden the midi controlls were gone and when i try to link them again nothing happens and i dont recall changing any settings. Whats going on? Im dying over here.

The Akai MPK Mini is USB-powered so make sure it is getting enough power on the USB port. For instance, don't connect it to an unpowered USB hub with other USB-powerd devices such as a portable hard drive or there won't be enough current available.

Is it showing up under your Midi devices in Arena preferences and is the Midi Input checked?
