My issue
With custom MIDI songs that I've imported, I've noticed that the tracks start to desync from each other, especially with larger/more complex songs. It seems that tracks with more stuff going on get slowed down while the rest of them carry on as normal. I can't attach the specific files I used, but I've noticed this issue is most prominent with a MIDI of Gusty Garden Galaxy (that I got from VGMusic.) Is this something that's avoidable or is it just a consequence of larger files

Thanks for the example file hint, merged with #62
