... and if you use the block registration, you and also assign F1-F10 to be your RIGHT hand voices per Registration recalled.
Each Registration can have it's own USER VOICE LIST ....
... or each STYLE can have it's own VOICE LIST TO STYLE (voice list for the right that depends on what style you use) ....
.... or each STYLE can have it's own VOICE TO STYLE (voices assigned to Arranger A, B, C and D so as you play a style and switch Arrangers, the voices change - activate on STYLE MODE - MODES 2/2).
Thanks,
AJ
