qmidi's Issues

SEG FAULT in Windows 10 in the MidiIn callback (Only in Release)

Hi, first off, thanks for this awesome library.
I had a hard time looking for the problem, because it was only occuring in Windows and in Release mode.

It was solved adding the return to the clear method of the MidiMessage class.

QMidiMessage *QMidiMessage::clear() { _status = MIDI_UNKNOWN; _channel = 1; _pitch = 0; _velocity = 0; _control = 0; _value = 0; _deltaTime = 0; _sysExData.clear(); _rawMessage.clear(); return this; }

So weird :D

Let me know if you're up for doing more stuff with this library! my email manuwind5 at gmail dot com

front() called on empty vector

When using the example application, with "Forward Messages"

Compile error

Hello,
i tried to compile this package using qt5:
qmake -project which created QMidi.pro file.
edited QMidi.pro file by adding
QT += gui core widgets
and appending
./libs/rtmidi/ to INCLUDEPATH += . line.
When i run make
i got output which i put to pastebin link.
