Rikki, thank for the find, you really dig in. (smile)
Bernie, my thoughts are from the Technic days when GM voice were not a good choice. And, you are right, we should be given a choice.

Let me share my game plan:
1-I accept everything on the Sx900 as is, for now.
2-Match songs with styles, save them to Regs. Eight songs to one bank.
3-Studied, in depth, what and how the Regs saves things.
The ideal band for a song like Misty is not used for Rock Around the Clock. The instrumentation is not only different, the instruments sound different. With that in mind I am creating an ideal band for different types of music, one bank of 8 regs. for each style of music.

1-Reg #1 saves, style, tempo, Rt1,2,3, left hand, and whatever I feel is important.
2-Regs #2 thru #8 one of the ideal bands I created. Regs #2 thru #8 only save instruments, volumes, Variations, no style or tempo. The Reg #1 sets me up, and I can use my ideal band. #2 thru #8.
Procedure: Select the ideal band, then create the #1 reg (Song, style, tempo, ect.

Variation:
1-Reg #2 thru #8 can be used to select a style which compliments the first style.
2-Reg #1 may select the intro. Reg #8 may select the ending. Reg #8 is the strongest band sound.

I have not found way to save the left hand without including the style in saving.

I am open to any ideas which can help and improve game plan.
