Bug from the forum: http://mixxx.org/forums/viewtopic.php?f=3&t=1704
Can confirm with fresh Mixxx 1.8.0 final installation / MacOS 10.6 / 10.5
Mapping controllers with the Midi Learning Wizard does not work.
This is a regression from 1.8.0 beta2
mixxx --mididebug shows that Mixxx actually receives messages from the controller, but the Wizard shows nothing.
Error message in the terminal:
Warning: [PM 0. VCI 300 DJ Controller]: QObject::connect: Cannot queue arguments of type 'MidiMessage'
(Make sure 'MidiMessage' is registered using qRegisterMetaType().)
