Voiceband for the iPhone

In my humble opinion, this is the coolest iPhone App ever. As they write on their website: "Voice Band introduces a revolutionary new way to make music - with your voice!".

Just sing into your iPhone and Voice Band transforms your voice into ten different instruments in real time. This App allows you to play along with your favorite songs in your iPod library.

It also includes a recorder which lets you build a song, playing one instrument at a time. When playing the guitar, you can use the built-in effects processor with distortion, reverb, and delay. Check it out at the wavemachinelabs.com/(..)/voiceband/. I will post my songs soon (if i dare).
