The MIDI event handling in InstrumentTrack was complex and buggy. It has been simplified now such that processInEvent() tries to handle note on, note off and key pressure events. The actions taken should result in equivalent calls to processOutEvent() by NotePlayHandle instances. The processOutEvent() function sends according MIDI events to the attached instruments. All unhandled MIDI events are directly forwarded to the instrument in processInEvent(). It's possible that some corner-cases are not handled yet with the new code and we have regressions now. Furthermore renamed midiTime/midiEvent to MidiTime/MidiEvent to match coding style. Closes #72.
