I was thinking how cool would it be to have a vocal App that would replicate middle 3 part echos of The Prophet Song. or Now I'm Here vocal opening. Unless there is a vocal App that does a similar thing? Likewise with Guitar Apps, it would be cool to have a Red Special App that replicates the 3 part red special guitar harmonies or create the Deacy amp sound. I currently annoy my girlfriend with The T-Pain auto tune App, lots of fun when people come over.
