This is a small program I'm working on. It's main function is to modify parts of MIDI files, with the ability to batch process (So you can apply the changes to 100's of files at once).
The main purpose of this, is that a lot of music ripped from games, like GBA, and NDS have the wrong instruments set upon rip. This will make the process easy and quicker, to correct some things.
I will also be using it to convert MIDI to a custom format for Project Collidascope, although this feature will not be made public.
