Songs made in OpenMPT
I haven't used this program much compared to the others, but it's really fun especially once you change the default keybinds that i don't like (although other people swear by them oop).
Unlike Furnace (which is a specialzed chiptune tracker) and Renoise (a DAW/Tracker hybrid), OpenMPT keeps it simple and doesn't have as many features but has a very straightfoward way
of doing things that i really like :).
BTW this was one of the very first music programs I've ever used, even before Furnace and Renoise. It helped that it was really accesible and free (Furnace wasn't a thing at that time)
