Here is a tutorial on creating a custom CP4 piano Performance using the S6 piano (APIANO3) for the Main Voice and the CFIIIS piano (APIANO2) for the Split Voice and saving it to a Performance location for instant recall.
I have just finished part one of my CP4/40 tutorial about the Performance mode in the CP4 and CP40. Although I refer to the CP4 in the video, it is also applicable to the CP40 since the operation of the two instruments is virtually identical. Look for part 1 in the Resources section of this site under CP4.
