I come from years of playing Yahamas, so I know there's going to be a learning curve on my new Casio CGP 700. But something's got me completely befuddled, and I've tried to find the answer in the manual and through trial and error but to no avail. I'm used to being able to change "styles" (Yahama) on the fly - and when I do, it's one button. Change the style, and the tempo is automatically adjusted to the default for that style. But, unless I'm really missing something, when I change a "rhythm" (Casio) on the fly - or even when the instrument is idle - it keeps the current tempo. To set it to the default tempo, I have to push the up and down buttons simultaneously which obviously adds a step to the process, making on the fly changes more challenging. I'm also confused with Music Presets. (Maybe that's the equivalent of Yamaha's styles?) It seems like selecting a Music Preset puts the machine into a mode with some sort of auto chord arrangement, unless one deselects "auto chord" (another step). Anyway, making my way around rhythms and music presets is baffling so far. Can someone tell me what I'm doing wrong? Surely Casio doesn't add steps to make changes in the sounds, rhythms, and styles, does it? If so, I'm going to be quite disappointed.
