Game Jam Music and Sound Generation

If you’re like me and lack the time or the skills to make music you could use algorithmic music generators.

A few that I like:

And some more generators I found at :

I use Windows and tend to prefer cgMusic as it is very user-friendly and you can tweak more specific random seeds and more generative options.
cgMusic also used by which generates an album and an mp3 immediately.
It can also be used commercially, according to Maciek’s comment at his codeminion blog link:

@alfwein Actually, I’ve been getting a lot of questions about the possibility of using cgMusic commercially and generally I was allowing it. The only thing I ask is that it is clearly stated in the credits that cgMusic was used during music production. Also it would be great if I could get a copy of the game, to see how the music was used 🙂
Anyway, this credit is important as copyright law is very unclear when it comes to algorithmic compositions. I would like everyone to avoid potential problems – after all the program can give two people identical results if the same random seed is used.


Wondering how to use the generated MIDI songs for your work? Generate and get the midi.
Then one can use TMIDI player from
to change instruments used of generated MIDI by any of the above, then play it and record it with Audacity ( ) to a mp3 or ogg etc.
For good sounding midi you need a better MIDI synthesizer, Microsoft GS wavetable synth won’t do.
I use CoolSoft’s Virtual MIDI Synth
Now the Virtual MIDI synth needs a SoundFont (the actual sounds of the instruments), here is a good collection of them
Personally I like OmegaGMGS2 by Rick Simon (~270MB)
