Hi Jokeyman123, I am familiar with one-touch preset mode, and I think you may have misunderstood my question, or maybe I wasn't clear enough, unless I'm missing something. I suspect that you're talking about the tone of the chords played DURING rhythm accompaniment. That's not what I'm talking about. I'm trying to change the tones used for chords played in the simplified chord mode that is activated once ACCOMP has been turned ON, but BEFORE any rhythm has actually been started. In this mode (assuming a simplified chord fingering modes is selected, e.g. CASIO CHORD), pressing a single key on the left side plays a chord. It's as if you've pressed all the keys in the chord at once. But the chord is played in an organ sound and cannot be changed. I want to be able to change it.
