I'm sorry, it's just that I can't make a good instrument out of it ;~;
Let me just say this: I don't like Klystrack; I do not like its own built-in synthesizer, and everything else about it.
What I DO like, is that it can import MODs and XMs. So I wrote a .mod in MilkyTracker and then opened Klystrack to import the .mod I created. Although the .mod is slightly butchered, it still sounds accurate to the original source.
