I stopped using arranger automatic functions in live work many years ago, but I do use my Ketron for speck work and initial conceptuals on film scores.

It works GREAT! I choose a workable tempo and, instead of using the stock intro's and endings, I use the drum track, the break function and embellish the intros, exits, etc. with a left-handed bass intro or ending. I always keep a keyboard on top with a really good finger bass setting. Sometimes, on live gigs, I use the arranger with the Hammond on top, with at least the auto bass off. That lets me embellish passing chords, sweeten endings and retard things like walks between cord changes.

I think this would work for a traditional arranger player. Just put a 2nd keyboard on top, stop the drums at an appropriate time and finish with a bass finish and right hand embellishes.

Practice is easy. Find a nice groove, turn off arranger functions, hold sustained right hand chords and concentrate on the bass line and embellishes. After you get comfortable, add additional right hand embellishments.

Maybe while we are all waiting out the virus, this would be a time passer and it could improve your over-all performance.

Play on!
