A QML version is now in construction. It's only a technology preview and should not be used for non-testing purpose.

Building QMidiPlayer

Please follow the instruction found in the file "INSTALL".

Warning: building QMidiPlayer for Windows is somehow a formidable task. Go ahead if you are ready to deal with metaphysics.
