Hey guys,
because I haven't found another way to do it, I made my own solution for that issue.
I did a Tutorial-video, which you can watch on YouTube.
My motherlanguage is German, I hope you can follow the steps anyways. (Check the video-description for each step)
If not let me know and I'll do a second Tutorial in English.
If you guys have different solutions for importing MIDI-Files to your KSP/ BSP please let me know.
I hope I can help some of you with my solution.
Here is the link to the video.
