PB window closes while trying to use a midi keyboard
I'm trying to use Piano Booster with a cheap MIDI keyboard, recognized as AKM320. But when I select this option on Midi Setup > Midi Input Device, and click the OK button, the Piano Booster main window closes.
With the PC keyboard, the program works well.
I'm using Ubuntu Studio 15.10, and Fluidsynth as MIDI Output.
