Imitone - The voice to midi controller!
I don't know if this will interest anyone, but I thought this was pretty damn cool!
I'm one of the people who almost constantly humms when I'm alone, there are very few times when I don't have a melody stuck in my head. I play instruments and I always found it to be a very giving and amazing thing to be able to create music, so when my buddy tipped me off to imitone I was pretty stoked.
What the application/plugin does is to translate the pitch of your voice into a midi signal that can be interpreted by a sound editing program (garage band, fruity loops etc.), enabling even those who can't play the keyboard or any instrument at all really to create music that is enjoyable to listen to.
They have a kickstarter open and even if there are just 4 hours left until it closes, I still wanted to share this with everyone. The way I see it, even if you don't have an interest in creating music or anything like that, this could still be a fun application to mess around with.
EDIT: Corrected typos and such.
