A Certain Format Does Not Work with Musescore

A lot of formats I find don't work with Musescore and every program I have found and compiled does not seem to be able to handle them aside from two, but they don't convert abc files to midi notation. I have compiled a ton of abc files over the years using the Starbound Composer or Maestro, which seems to be compatible to every abc formatting I've seen. Unfortunately, I've stored files as abc files and have lost the midis to many files and am unable to convert my abcs back. I was hoping Musescore would be able to with this plugin, but it severely butchers the songs. Here is an example of a song that it is unable to be converted properly into Musescore from the abc version of it. I used the midi I found to convert it via the Starbound Composer. The midi works fine when put into Musescore but not the abc. Please expand the compatibility of the plugin to allow this version of the abc formatting to be compatible. It would save me and many others who have used the two programs a lot of time, especially since to be able to get the missing midis, we would have to recreate them, which is pretty much impossible since we all suck at making music. Thank you for your consideration!
