A while back there was a thread about a Yamaha keyboard that was to have a singing head.

If you have a Power Mac you can have the singing head today (without the head).

"Vocal Writer" sings Midi Files with Lyrics for $99

This is not an ad. I don't have a Mac and I'm not involved with it I just found it while looking for the old program I used to have.

Go to the link below to hear samples on any computer using the Quick Time Pluggin.

I must say it's very impressive.
