Not to take anything away from Donny's playing and entertaining talent, remember he uses a lot of mp3's for backing, so the keyboard is not as important most of the time.
Wrong my friend,
......I use it ALL depending on the gig, 4hrs, 1 hr, 8 hr doubles, etc,..on a NH gig I "NEVER" use anything but live style play,.....styles all night many times or combined with mp3 backing tracks that I have created and recorded many on the arrangers or in combo with SMf files also, & multitracking too,.. DJ'ing also with no Kb at all sometimes too,...who cares? You gotta have it all and be a good singer too and be ready to use it at a moments notice...a one trick pony ain't gonna cut it in todays world of music.
