How is this related to MIDIJam?
MIDIJam is the original 3D MIDI file visualizer, created by Scott Haag. midis2jam2 is a separate project that remasters it for modern computers, with new instruments, graphics, and settings.
What's a MIDI file?
A MIDI file isn't a recording. It's a set of instructions for playing music: which instrument plays which note, and when. That's how midis2jam2 knows exactly what the band should play.
Where do I get MIDI files?
Many websites offer free MIDI files of popular songs, game soundtracks, and classical pieces, and most music software can export them. If it ends in .mid, midis2jam2 can play it.
Is it really free?
Yes, and it always will be. midis2jam2 is free and open-source software, licensed under the GNU General Public License v3.
What can I run it on?
Windows, macOS, and Linux computers, plus Android phones and tablets through Google Play.
Can I change how it sounds?
Yes. Load any SoundFont you like, or send the music to a physical MIDI synthesizer instead.
