Can anyone tell me how to access all the drum tones on this accordion? I only know how to turn on an off the drum sound when I am playing but am aware there are many more drums sounds to explore. I have the entire list of drum tones and it appears there are 127 of them but I do not know how to get to these sounds. My friend who plays violin is coming over in a half hour and she had been asking me about how we can layer in more of a soundscape. I might have to learn to do that on my bk-7m which I don’t know how to use yet but for now I just would like to access the drum sounds on the accordion. Thank you!
