Here is what I purchased. When I put my songs together anymore I just use this. I do the lead vocal, transfer the song to my MR8 HD/CD then I hook up my vocal harmonizer as to where I mute the lead vocal, sing and let the vocal harmonizer do the rest. You can control pitch here. There is a little learning curve here but not to bad. Here is the link.

Music is an expression that is a universal language, Never criticize anybody to harshly. They need time to grow but when they do, they do. Always be kind in what you say and do because the man upstairs is watching.
