That is a very interesting video which has introduced me to a product which I knew little about.
This is the future. It looks like a lot of fun and it might even allow me to write my first opera!<grin>. I was knocked out by this and if pg music are smart they should get on board and develop "Singer In a Box"!
The software price is very reasonable so I'm going to give it a try and see where it takes me. The only downside I can see is that the workflow seems somewhat laborious but should speed up with practice.
