To save to registration memory, press button on other side. Memory I think. No need to keep pressing memory and 1-8 button simultaneously. As long as you press 1-8 less than 1second after pressing memory it will save. It will blink to indicate saving. Read manual for NEW playlist function which improves use of more than 8 registration. With 2 pedals you can press one to change registration from 1 to 2 to 3 etc without using hands. The next pedal to move 8 to 7 to 6 etc....
Great thanks so so much ! However I wish you had used the SX700 because that's what I have in the church and it's just hectic setting it up because it's still new . But I believe by God's grace we will get it right.👏👏🙏🙏
