On some arrangers, you can use a sustain pedal to hold the chord until you decide to change.
That frees up both hands to do whatever you wish.

Thanks Don,
I’ve never really checked it out, 61 notes is probably a limiting. 88 note controller on the horizon. Haha ( in my dreams, and hubby’s nightmares)

Maybe that’s what the guy I mentioned was doing, using sustain pedal to hold the chords.
I was just so dazzled by his expertise at the time, I couldn’t work out what he was doing.
