I saw a You Tube video where you can have a particular performance open up when you turn the CP88 on. For instance I have my own C7 piano sound that is on page 18 that I'd like to have open and not have to scroll through to find it. I did the new OS update and reloaded my custom sounds to different pages and would like to re-assign. I can't find the video and forget how to do this. Can you please share the way to save a certain sound to open when the unit is turned on? I'll write it down this time!!!! Thank you.
