Good points bernie. And good video Chas, I've watched it before. I've gone thru the same progression of drum machine to arranger. I feel if your doing all you can live IE:Singing and playing the keyboard what's wrong with filling the song in with a track. It's like I'm playing with a band. I use about 80% edited Styles on my BK9 and because of the wonderful ability of being able to put jump markers into SMF's I also use those, again very edited. The jump markers give me the ability to extend a song if necessary. That was the main drawback of me using them in the past. It's when it gets to the point of lip syncing or faking playing that I don't like it.
