This unit seems to be the next incarnation of the Roland Discover 5m and Ketron Midjay. It utilizes newer technology to allow singers and solo performers to embellish their performance.

This is certainly not a new concept...just the latest technological self contained unit...and it sounds pretty darn good. Heck...back in the 70's I would pre-record background harmonies and keyboard parts on sound on sound tape decks, and then play them through my pa as I sang a played guitar. People thought I was lip syncing at the time.

Donny continues to share technology as he finds it on the web. I for one, appreciate his discoveries without judgement for his motives. Technology will continue to advance whether we like it or not. Someone still has to create the music. It's up to the live performer to sell their reproduction of it.
