This is not a direct response to the question but it's related. Settings for the volume of playing the keyboard are made in the Mixer. Settings for the volume of the rhythm styles are set in Function. When I first got my WK-7500 it took me a long time to figure this out. I didn't understand it from reading the manual, and when I called tech support they couldn't understand my question. Now that I know how to do this I get better results. After I have good balance between Main Voice, Layer, Split and Rhythm I store it as a Registration Memory. One possible solution for Cman is to store two or more Registration Memories in the same bank, and then go back and forth as needed. You can also check Function>Performance>Touch and make sure it's set to 2.

Thanks so much for the quick reply. This info is so helpful. The attached page (162) from my owner's manual gave me hope that I could send and receive on all 16 channels. When I went to page 36 I saw that the B channels must be for recorded songs, not live performance.

This is for live performance by two keyboard players, not for recording. I would like to transmit MIDI note on/note off from my WK-7500 to an external keyboard by playing the Casio, without using a computer. I would like to transmit right and left hand notes on two different MIDI channels. I would like the external keyboard to receive the messages on high numbered channels so that I can use 1-8 for playing the other keyboard. I have a USB to MIDI interface, and in testing it I found that it's working for transmitting Channel 4 from Casio, and receiving Channel 4 on external. The available sounds on the external are better for the particular music I'm creating.
