Hi all,

who can help me?

My problem with the MIDI stuff is this:

I try to move the MIDI output to a static methode like 
MidiData::getMidiList(...). The header file looks like this:

class MidiData {
public:
	static DeviceManager *midi;
	static bool midiInUse, midiStopPlay, devReady;

	static bool initMidi();
	static void closeMidi();
	static void getMidiList(TabTrack *&trk, MidiList &ml);
	static void stopPlay();
	static void playMidi(MidiList &ml);
};


It compiles without errors but linking fails. Here the output:
