So I think it would be cool if we were able to upload and download our MIDI files. It would be a more creative way of sharing our sounds (even though its just the map of a sound) and gives the person downloading more freedom with the sound, and they can make it "their own" thing easier.
What say you?
How about Freemelody.org?
Freesound is not for music.
