Another addon question to my one above — to switch between “Processor A, and Processor B” you suggested I use :
#define KEY_MACHINE (KEY_USER1 & KEY_KILL)
Which sucessfully acts as a ‘toggle’ — but that is problematic (as I must know the original state of the machine to keep track of weather the screen is displaying the parameters for A or B).
Is there a sysex or bit I can send to definitively switch the unit to the Processor A or Processor B screen?
