defMON wiki

This is the home of defMON — a music editor for the Commodore 64. There is no official support for the program, and even no official manual, but at least there is this wiki that allows defMON operators to act in a collaborative fashion for the sake of accumulation of information. Occasionally the author of the program may add some info as well, but that should be considered a bonus.

Contributions to the site are encouraged. Just register and go ahead!
