Hello! I posted here a long time ago about this topic in a now retired thread. Here is my latest video that demonstrates my generative/reactive music player:

" >Latest Generative Music Video There are still bugs left to fix but I think that it sounds better and is more varied now than before. Old thread Enjoy!

That sounds really great! I think to produce something by my own as well - I think every game has to have its characteristic music and if you take something that already exist it wont ever be unique and therefore not characteristically.

I can really recommend to try yourself. It is very fun :)

I started by reading the book "The Complete Idiot's Guide to Music Composition" and tried to automate the melody and harmony generation methods described in there.
