@Drakonis I use differents softwares and plugins hosts to embellish the generated midifile. Thank you for your comments.

I noticed the title, because I also have a generative piece of music called "Fractal Serenity" (I am making a 3D music video for it: http://www.youtube.com/watch?v=gOROyAQBgDA ). After listening to and enjoying this music from you, I found the "SonicMood" software, and bought it! Thank you for the tip! I like your choices of instruments, and the slight reverb on this, warm and gentle. Did you use GarageBand for the final music recording?
