I see your code in

QMidi/examples/qtplaysmf/playsmf.cpp

Line 34 in 84a2d65

for (QMidiEvent* e : events) {

and i try to change tempo (BPM) in real time playing, But not working.
So can you recommend me how ?

If you just want to change speed, it should be more or less easy to do that -- just apply some sort of scaling factor to the ms times. Otherwise, you'll need to modify the Tempo events.
