Thanks @Boii1, I'll take a look. Can you provide an example of a midi file that's causing this issue? Wondering if this is happening because you're providing a file with fewer than 4 tracks.

I am having the same issue. My midi file is more than 4 tracks, maybe this could be a problem???

I also encountered this issue. This is the sample file.

Maybe the cause of reduce error is because the midi file has fewer than 4 tracks while the tool forces 4 tracks to be assigned.
