I may have stated it wrong, but all is well with saving something to a registration. It is experimenting by trying out different voices to hear how they will sound that is a several step process with the synths. It will start with arpeggio, so I go to that screen and switch to harmony and play with those. Then, if I try a different synth, it starts out on arpeggio again and I have to go back to the screen and change it to harmony. Seems like the default for synths is arpeggio?
