HI Totomo
Yes.... What you've illustrated here is quite correct.
It's always amazing to some of us that keyboard players will go out and spend hundreds, even thousands of dollars/ pounds/ whatever, and then can't be bothered to look in the manuals, whether online or on paper to enhance their enjoyment of their chosen keyboard.
I know when I learned to play the church organ years ago, before I was even allowed to play the instrument, I was taken on a very thorough and informative tour of the workings of it, so that I understood exactly how it worked.
Same with a keyboard. There's so much 'under the hood' but if as an owner you're not interested enough to even look, you'll never get the best from it. Crafting it to your own requirements is very rewarding.
