Sorry Donny, I worked in an organ store, and took some organ lessons from the teacher, who became a close friend, and he did not play over a style. The drums were the only automatic thing. Bass, right hand, left hand, and auto drums, no style.
I attended a work shop with organist Hector Olivera. He spent 25 minutes setting up one song. Nothing automatic, just instrument and volume changes. On occasions he changed some chords.
But – as time progressed, they began to play over styles/rhythms.
