Thanks Don. It's been quite a while since I sold the PA3X. I was never able to get a voicing change in the middle of a measure with anything but a STS change or a manual voicing change. Songbook and Performance changes seemed to be delayed for me. I guess I still want to play like the old organs with pistons that worked instantly like the Technics Panel Memories do. My Roland Combo organ works that way but the little Roland BK-5 is more like the Korg stuff with voicing changes at the start of the next measure.
