I’m sorry but your request to create tutorial for every single DAW is out of our scope. I would agree with you if the uTool or the player device does not detect the song properly. But in your case the midi file shows the same length in other applications like Windows media player as well in uTool which means somehow the midi file more than 6 minutes long.
If you send me a midi file I can take a look but unforutnately I cannot tell you how to create and export the file.
