Yes, it does work. Although I find I get most of what I need on my arranger (PA1x Pro) I still use some MIDI files so I don't have to worry much about chord changes and doing fills, etc. It also breaks up some of the styles I use for some variations. Most of what I do is praise and worship sionce I do ministry. I am basically the one man band who does ministry, but I did use a copuple of MIDI files for a Christmas Open House gig at a local bank last week. I didn't have to use any of my gear though, because I have a good relationship with the local music store. They set up a Clavinova CVP-307 free of charge as advertisement. A very nice instrument with real usable styles and great sounds.
