;;;; The Song Voice Mode Select the specific drum set to be edited by placing the cursor on the drum set number and selecting via the [-1] and [+1] buttons or by using the SHIFT-Number entry method. Only certain drum instruments can be edited, and these are indicated by dots on the appropriate keys in the graphic keyboard display at the top of the display panel. Use the [OCT DOWN] and [OCT UP] buttons to access the full range of drum instruments, and press the corresponding micro-keyboard key to select an instrument for editing. When a drum instrument which cannot be edited is selected, the controls on the display appear "grayed" and cannot be accessed.
