I've been tweaking the rotary controls in my YC88.  I'm having an issue slowing down the horn speed on the "Studio" rotary.  Each time I make adjustments I try and save the settings but the changes do not stay.  Each time I switch my sounds in the favorite banks, they revert back.  Is there a step I'm missing in saving the adjustments?  Also, when you make these changes to rotary speed, acceleration, and deceleration, is it universal for all organ models or do you have to save changes at the individual sound level?  Thank you.
