@timstoponder: Hi! So basically this is how you set your preset tones for Casio Ctx3000 1. Choose a base tone 2. Press upper layer 3. Then choose a tone that you partner with your base layer 4. Press and hold store + choose the number below registration 5. You can repeat the process and save up to 8 presets I hope it helps! :) #casioctx3000 #casiopiano #pianotutorial #pianobeginner #keyboard
