Editing MIDI file loop points for GBA music

Hoping for someone to point me in the right direction. Is there any sites that are useful for resources on editing MIDI files? I’m trying to make a GBA game rip and increase the amount of loops some songs have but not sure where to look

Not sure if you’ve had any luck figuring it out already, but Garageband is simple (and free I think?) for editing MIDI if you’re on Mac. Otherwise there’s lots of PC software for editing MIDI, you could also use Cockos Reaper which I believe is donationware, however might be a little less intuitive to use, will still get the job done.

I’ll definitely check them out! I use a PC for future reference
