Hey, Don, I used an old Auto Orchestra for years. You held the bass note with your left foot and triggered the minors, Dim, 7ths, etc. with the heel of your right foot.
You can do the same thing with a variety of Ketron keyboard arrangers or modules. In fact, the Ketron is the current version of the old Auto Orchestra. Last I checked, they had the same 13 note bass unit I have upstairs with the old Auto Orchestra.
Get hold of Frank (Frankieve) here...he's a Ketron dealer and a really good guy to deal with.
Welcome, by the way!
